West Oxfordshire Design Guide

1 Introduction The purpose of this Guide is to describe the qualities and characteristics that make West Oxfordshire special – its landscapes, settlements and buildings – and to describe the ways in which good design can protect and enrich the character of the District. Design is central to a wide range of issues, from the colour of a front door to the layout of a new housing area. Whatever the context, being ‘fit for purpose’ should never be enough. Outstanding design makes places special, is life-affirming, and forms a material legacy by which future generations will know and judge us: for this reason it should be the aim of all those involved in the change or management of West Oxfordshire’s built and natural environment.

The Guide provides advice to supplement policies contained in the West Oxfordshire Local Plan. The overall aim of the Plan is:

“To protect and enhance the natural and built environment in West Oxfordshire in order to pass a worthy legacy on to future generations whilst at the same time securing new development of a good environmental standard which will provide the necessary residential accommodation, jobs, infrastructure and facilities required to meet the social and economic needs of the local community as well as visitors to the area”.

The West Oxfordshire Design Guide has been subject to public consultation and has Supplementary Planning Document (SPD) status, making it a material consideration in the determination of planning applications.

Local design characteristics This Guide is intended to encourage a high standard of design, and to promote new development which respects and fits in with the character of West Oxfordshire. The Guide sets out the characteristics which make West Oxfordshire unique and which can be used to influence new designs that reflect and enhance local character. The towns and villages of West Oxfordshire have a distinctive character that is worthy of special protection. They may contain ancient listed buildings or comparatively recent structures, as well as lanes, squares, greens, gardens or parkland. This Guide is concerned primarily with the impact private buildings make on the streets and open spaces which constitute our villages and towns. It sets out detailed advice about the prevailing settlement types and their historic form of development; including plot sizes, boundary treatments, and the shape of buildings and their relation to the street. The topographical relationships between these settlements and their landscapes are also described and analysed, providing a framework for any future development.

“ The towns and villages of West

Oxfordshire have a distinctive character that is worthy of special protection. ”

Innovation in design An appreciation of the existing historic environment is essential when creating new development sympathetic to its surroundings. However, in practice this does not require replication of historic building styles. Many architectural styles have evolved over time and may be interpreted in a contemporary manner. In some situations modern, innovative designs may positively enhance a traditional or neutral setting. In a largely traditional context, it is essential for contemporary proposals to demonstrate exemplary design quality.

The Council is committed to promoting sustainable development, including the preservation of energy and resources and the reduction of pollution. New development should further these aims, considering such factors as building orientation, re-use of materials, insulation, solar shading, water conservation and innovative heating and power generation systems.

Design and Access Statements should address these issues and provide an assessment of the environmental impact of the proposed new development (see Chapter 5).

2.2

West Oxfordshire Design Guide

The character of West Oxfordshire West Oxfordshire is a predominantly rural district.

It embraces large areas of unspoilt countryside and a diverse pattern of landscapes, including rolling uplands, river valleys, historic parkland, remnants of ancient forests, low-lying farmland and riverside meadows. It contains within its borders scattered villages and some larger settlements. The architectural and landscape character of West Oxfordshire is chiefly determined by the local oolitic limestone underlying much of the District. However, there are significant variations in traditional architectural forms in different parts of the District.

Today a wide range of architectural forms and synthetic materials are available. These, when used alongside traditional forms and natural materials, may appear alien and out of place. Unless special care is used in the design and choice of materials for new buildings, the character of our historic settlements will be progressively eroded and ultimately lost to future generations. Good design, which responds sensitively to its context, should overcome these problems.

Roughly one third of the district forms part of the Cotswolds Area of Outstanding Natural Beauty (see page 3.2 for further information together with a map).

Architectural character areas Just as the landscape of West Oxfordshire does not remain consistent throughout the District, so it is with the architecture and building materials. Marked regional variation exists. For this reason, guidance specific to each character area is crucial if this differentiation – and the richness of the District as a whole – is to be honoured.

Four distinct character areas have been identified in West Oxfordshire: the Thames Vale, the Limestone Wolds, the Ironstone Valleys and Ridges, and the Northern Valleys and Ridges. Each area is topographically and geologically distinctive, as well as exhibiting clearly discernible variations in its architecture and materials. The areas are identical to, or are amalgamations of, the 12 landscape character areas identified in the West Oxfordshire Landscape Assessment 1998. They are discussed in detail in the following pages.

The use of materials Burford

Local character is particularly marked in West Oxfordshire, where the local oolitic limestone is the dominant material. It has been cut into smooth ashlar facings for the walls of important buildings, laid as coursed facings for walls or as coursed rubble for lower status houses, cottages and barns. Limestone was burnt in kilns to make quicklime. When slaked with water, it formed the base for lime mortar, lime plaster and a weatherproofing external limewash.

i. Thames Vale This area lies to the south and east of Witney on the north bank of the Thames. Most of the area is below 85 metres, and changes in ground level are barely perceptible. This area includes the Vales of Bampton and Eynsham, The Lower Windrush Valley and Eastern Thames Fringes, and the Western Thames Fringes Landscape Character Areas.

The flat, predominantly agricultural landscape is made up of floodplain pasture and vale farmland, and overlies heavy clay, river gravels and silts. The character of the landscape is largely determined by the process of enclosure. Large fields of regular shape with a strong structure of hedgerows are crossed by long, straight roads, with the occasional willow-lined ditch. There are significant blocks of oak woodland, and gravel extraction has created large wetland areas in the Lower Windrush Valley.

Distinctive building features include timber framing, and materials relating to the clay that underlies the northern part of the area, such as brick and clay tiles. The vernacular houses and cottages are typically long and low, with steeply pitched roofs.

ii. Limestone Wolds The central area of the District lying between the 85m and 200m contours is formed by the dip slope of the Cotswolds. It is made up of the Enstone Uplands, Eastern Parks and Valleys, Upper and Lower Evenlode Valleys, Wychwood Uplands, Upper Windrush Valley, and the Shilton Downs Character Areas.

The area has a highly distinctive open rolling landform. The northern and western part of this area of the Limestone Wolds is included within the Cotswold AONB, which stretches from Bath to Stratford. The undulating landscape is cut into by the rivers Windrush, Evenlode, Glyme and Swere. These create picturesque winding valleys with contained views. Historic Parkland (including Cornbury, Blenheim, Rousham, Ditchley and Heythrop) and fragments of the ancient Wychwood Forest, form landscape elements of exceptional importance.

Fields tend to be large and regular. Dating from enclosure, they are bounded by dry stone walling or hedgerows.

Distinctive building features include the famous, creamy limestone which, together with the extensive use of limestone slates for roofs, creates built environments of strong local character and consistency. Long fronts, narrow gables, steeply pitched roofs and dormer windows are typical.

iii. Ironstone Valleys & Ridges This small area in the north-east of the District has a diverse character and a complex, hilly landform.

The distinctive orange marlstone and red soils result from an underlying geology rich in iron bearing rocks and clays. The landscape features a patchwork of fields, hedgerows and woodland, and trees are unusually abundant.

The settlement pattern is sparse, with the scattered villages and hamlets typically occupying the sides or bottoms of the hidden intimate valleys that cross the area. The main settlements are Great Tew, Sandford St. Martin and The Bartons.

Distinctive building features include the striking orangey-brown lias limestone. This material is used in larger blocks than the neighbouring oolitic limestone. Because it is soft and easy to cut and carve, its details and form tend to be simpler and more massive than those carved from the finer, harder stone. Stone dormers, stone copings and thatch are also more abundant here.

Walling materials

• Lias limestone rubble in wide bed sizes. The stone may have a blue or green appearance when fresh, but oxidises to a deep, warm gingerbrown when exposed to the air, hence the name ‘ironstone’.

• Lias ashlar dressings, label mouldings and chimneys.

• Oolitic field and boundary walling, laid in very narrow beds.

• Red ‘Oxford’ brick used for chimneys, dressings and some outbuildings.

iv. Northern Valleys & Ridges This small area in the north-west of the District has distinctive open rolling countryside with high ridges overlooking the valleys below. The area has a variety of exposed geology on the valley sides. The local stone includes grey oolitic limestone, and ginger to light brown lias limestone.

Chipping Norton, the principal settlement, occupies a high valley side setting. Most of the other Northern Valley settlements, however, have more sheltered sites, or lie in valley bottoms. Field size varies greatly here, and generally decreases from the open and elevated topography into the folded valleys below.

This topographical and geological diversity is reflected in the building materials and their use.

Although oolitic limestone predominates, ironstone also appears for dressings, and sometimes for complete buildings. Stone walling appears in a variety of forms, featuring squared or rubble stonework, sometimes arranged in courses, sometimes not, and in a range of bed widths.

Dormers carried up within stone gables flush with the face of the main wall, and Welsh slate on later houses, are notable features of the area.

3 Biodiversity and landscape character Traditionally, nature conservation has entailed the isolated protection of designated sites and endangered species. However, recent Government guidelines (PPS9: Biodiversity and Geological Conservation) recognise that these assets are integral to the fabric of the wider natural environment and, specifically, to biodiversity (the variety of life on earth).

The three main objectives listed in PPS9 are: •

to promote sustainable development - by ensuring that biological and geological diversity are conserved and enhanced as an integral part of social, environmental and economic development, so that policies and decisions about the development and use of land integrate biodiversity and geological diversity with other considerations;

•

to conserve, enhance and restore the diversity of England’s wildlife and geology - by sustaining, and where possible improving, the quality and extent of natural habitat and geological and geomorphological sites; the natural physical processes on which they depend; and the populations of naturally occurring species which they support;

•

In 1994, the Government published the UK Biodiversity Action Plan (B.A.P.) with an overall aim of ensuring that there is no net loss of biodiversity. In response to this plan Oxfordshire produced its own ‘Action for Wildlife’ Local B.A.P. framework. Several Local Habitat Action Plans for Oxfordshire have also now been produced.

Information on Oxfordshire’s Biodiversity and Habitat Action Plans can be found at: www.ukbap.org.uk/lbap.aspx?id=454#5 www.oncf.org.uk.biodiversity/biod_framework.htm The management of biodiversity, as well as being important in its own right, has profound implications for the maintenance and enhancement of local character. This forms a core component of the West Oxfordshire Local Plan, with Policy NE3 stating: “Development will not be permitted if it would harm the local landscape character of the District. Proposals should respect and, where possible, enhance the intrinsic character, quality, and distinctive features of the individual landscape types”. Within this context trees, hedgerows and other forms of vegetation often represent significant and distinctive components, noticeably varying across the District and greatly influencing local landscape character.

to contribute to rural renewal and urban renaissance by -

- enhancing biodiversity in green spaces and among developments so that they are used by wildlife and valued by people, recognising that healthy functional ecosystems can contribute to a better quality of life and to people’s sense of well-being, and; - ensuring that developments take account of the role and value of biodiversity in supporting economic diversification and contributing to a high quality environment.

West Oxfordshire Design Guide

3.1

Vegetation character areas The management of flora and fauna should aim to reinforce or restore those landscape characteristics which contribute to local distinctiveness and biodiversity. In general, intervention should aim to restore diversity and structure to the landscape; for example, through the planting of trees and hedgerows, and the creation of habitats in order to reinforce the characteristics of a particular landscape type.

In terms of vegetation type, West Oxfordshire can be divided up into three broad character areas – the Limestone Wolds, the Clay Vale, and the River Meadowlands – each featuring a distinctive combination of key and significant species. It should be emphasised that these divisions represent the landscape character of the District expressed in its simplest terms. A more detailed analysis of the landscape, geology and wildlife of the District is contained in the West Oxfordshire Landscape Assessment (copies of which can be viewed at the Council Offices) and the Oxfordshire Wildlife and Landscape Study: www.oxfordshire.gov.uk The West Oxfordshire Landscape Assessment also includes detailed information on landscape condition - which areas are in poor condition and need enhancing; and which are in good condition and need preserving - together with a ‘Landscape Enhancement Strategy’ map for the whole District. Meanwhile, the Thames Valley Environmental Record Centre (TVERC) website includes a map showing target/ opportunity areas for biodiversity enhancement in the District: www.tverc.org Roughly one third of the district forms part of the Cotswolds Area of Outstanding Natural Beauty (the largest AONB in Britain, totalling over 2,000 sq km).

The primary purpose of AONB designation is the conservation and protection of natural beauty, wildlife and cultural heritage: aims framed up and given a statutory footing in the National Parks and Access to the Countryside Act 1949. The Act distinguishes AONBs from the National Parks, where the objectives of outdoor recreation and public understanding and enjoyment are deemed of equal importance.

The Cotswolds AONB was designated in 1966, with revisions to its boundary confirmed in 1990.

Historic landscape types

Historic parkland

Landscape character is founded on indigenous landform and vegetation, but has been largely created by human interventions over many centuries. The survival of evidence of historic land management methods, the ridge and furrow of medieval open fields and the variety of later enclosed field types, has left clear signs of the complex evolved landscape history of the District.The historic imparked woodlands, including fragments of the ancient forest of Wychwood, are especially valuable assets in the District. An understanding of these landscape types is crucial if the biodiversity and local character of the District is to be maintained. The identification and study of these has led to a number of projects whose aim has been the restoration, conservation and enhancement of these assets.

West Oxfordshire (in particular the north-eastern portion of the District) is unusually rich in historic parkland. Some landscapes, such as those at Woodstock and Cornbury, were ‘imparked’ (enclosed from ancient woodland) in the Middle Ages, to create hunting grounds for royalty and nobility. A second wave of development in the 17th century saw the creation of the landscapes at Ditchley and Chastleton.

However, the majority of the District’s historic parks, including those at Rousham and Heythrop, were laid out in the 18th century. These historic parks are inextricably linked to the rise of the great estates and the establishment of large country houses.

Woodland At one time much of West Oxfordshire was covered by the royal forest of Wychwood. By 1086 it covered at least 180 square miles. Since then, however, vast tracts of the forest have been cleared, leaving behind fragmentary copses and woods. Many West Oxfordshire villags, including Finstock, Ramsden and Leafield, originated as clearings in the forest and owe their distinctive straggling form to haphazard growth as the land was gradually cleared. The remnants of Wychwood are highly important, both for their natural and their historical significance. The parishes of Cornbury and Wychwood, together with Swinbrook and Widford, contain sizable areas of ancient woodland.

3.4

In West Oxfordshire, Blenheim (successor to the medieval Woodstock Park) is pre-eminent and is designated a World Heritage Site. Designed by Lancelot ‘Capability’ Brown and others, it covers an area of 1,000 ha. Other major figures from landscape history are well-represented in the District, including William Kent at Ditchley and Rousham, and Humphrey Repton at Sarsden and Great Tew. The creation of the great 18th-century designed landscapes, which may possess both picturesque and formal qualities, entails three main forms of human intervention. The first of these is physical landscaping and the creation of formal features such as terraces, parterres and pools, or informal features such as manmade landforms and lakes. The second involves the planting of trees and other vegetation, either in formal avenues or blocks, or in naturalistic clumps. Finally, there is the addition of built elements, in the form of buildings, bridges, monuments, follies, and eye-catchers.

West Oxfordshire Design Guide

Lowland heath Heaths are areas of open, relatively barren land, often resulting from forest clearance. They are characterised by poor-quality, free-draining soils that are high in acid and low in nutrients. This relatively hostile environment leads to the creation of highly distinctive habitats that support a unique combination of plants and animals.

The enclosure of medieval open fields and forest clearance by major landlords had occurred from the mid-17th century. The pace of enclosure quickened from 1750 when Acts of Parliament came into effect.

Open fields and common land were systematically enclosed and land ownership consolidated. The final acts of this process were the mid-19th-century clearances and enclosure by the Crown Estate of Wychwood, west of Cornbury Park.

The process of enclosure has left a variety of field patterns, defined by hedgerows and dry stone walls. The enclosure fields are smaller in the valley landscapes and larger on open land and the exposed wolds, and more regular than the medieval assarts and closes.

Certain tree species – such as pine and silver birch – readily establish on heathland. Historically, cutting such trees for firewood, or allowing animals to graze, restricted tree growth and protected low plants, such as heathland grasses, heathers and gorses. The decline in such practices has seen much heathland reverting to woodland. There are several important remnants of lowland heath in West Oxfordshire, including a notable area at North Leigh Common.

Meadowland

Historic field patterns Significant areas of medieval farmland within the District were cleared from the forest as ‘Assarts’.

Much arable manorial land was worked in strips in common fields. Ploughing patterns led to ‘ridges’ where the ploughsoil accumulated between furrows defining the narrow plots – or furlongs – into which open fields were divided. ‘Headlands’ at the end of the strips were where the plough was turned. Manorial landholders also had access to common pasture and woodland. Small and often irregular ‘closes’ around the edges of settlements are also characteristic of this period, and historic field names sometimes relate to the original owner of the land (‘Burtons Crofte’) or its location (‘Towne Close’).

Meadows form a distinctive low-lying landscape type and fall into two principal categories. There are those areas adjacent to rivers that experience regular winter flooding; and those in which river water is persuaded to flow through an area of land by means of a series of manmade ridges and ditches. Historically, meadowland has been used as pasture for the grazing of cattle; the flood water having the effect of keeping frost out of the ground, thereby allowing the early spring growth of grass. The alluvium deposits left on meadowland by the receding waters, meanwhile, provide highly fertile soils able to support a rich and distinctive array of flora and fauna. Much of the Thames Vale area in the south of the District is characterised by this landscape type.

West Oxfordshire Design Guide

3.5

Biodiversity and new development The stated aim of the West Oxfordshire Local Plan is:

“To protect and enhance the natural and built environment in West Oxfordshire in order to pass a worthy legacy on to future generations”.

Specifically, it is incumbent upon the District Council to help achieve the targets set in national and regional Biodiversity Action Plans (B.A.P.s). New development, great or small, residential or non-residential, can have profound consequences for local landscape, habitats and wildlife. It is therefore important that such issues are considered prior to the submission of an application. When considering development proposals, the council aims to ensure that there is no net loss of biodiversity. Schemes should: • Aim to maintain and enhance, restore, or ideally add to the net biodiversity and geological conservation interests; • Avoid direct loss or damage to priority habitats or species; • Mitigate/compensate for any unavoidable loss or damage to habitats or species; • Incorporate beneficial biodiversity and geological features within the design of the development; • Encourage habitat creation.

For new development, be it a single dwelling or a large scheme, the existing landscape, vegetation and wildlife context must be carefully considered.

Established plant and animal communities must be conserved during and after construction, and provision must be made for such assets long into the future.

There may be biodiversity enhancements through the creation or restoration of habitats - particularly indigenous habitats - which support rare or protected species. Planting schemes should reflect not only the broad landscape character as set out in the Vegetation Character Areas map, but also the specific local context as described in the West Oxfordshire Landscape Assessment and elsewhere. Further to these

3.6

considerations, specific attention must be paid to the following habitats and wildlife:

Trees and hedgerows As well as being important natural components in their own right, contributing much to the appearance and character of the District, trees and hedgerows also form vital habitats for wildlife, and can provide important corridors between isolated habitats. Some hedgerows and trees are protected by law, so if your application involves the removal of a part or the whole of a hedge or tree, you should first contact the District Landscape and Forestry Officer. If the application involves planting, careful attention should be paid to the species used. Whilst local, native species will often be the most appropriate choice, non-indigenous ornamental species (for example) may sometimes be an appropriate alternative. Again, the District Landscape and Forestry Officer can provide guidance.

Watercourses and ponds Watercourses - including ditches, streams and rivers - together with ponds, support a wide range of wildlife.

Water Voles and amphibians (most notably the Great Crested Newt) are protected by law, so if your application affects a watercourse, pond or surrounding habitat, you should first contact the Species Officer at English Nature or the County Ecologist (see overleaf).

Bats It is illegal to kill, injure or disturb bats or their roosts, both occupied and unoccupied. As well as occupying natural sites, such as trees and caves, bats roost in roof and wall spaces. For this reason, work in these areas, including the blocking up of bat entrance holes, can disturb them. If you are concerned that your application may affect bats, you should contact the Species Officer at English Nature or the County Ecologist. If your application covers an unoccupied building or may affect a tree or trees with cavities used by bats, it may require a survey by a qualified professional, which should then be made available to the planning authority. English Nature can supply a list of licensed bat surveyors, and DEFRA provides information about licences and legal protection: www.defra.gov.uk

West Oxfordshire Design Guide

Birds All birds and their nests are protected by law. For this reason, no work that can disturb them – including building work, tree felling and hedge clearance – should take place in the breeding season (which generally runs from the beginning of February to the end of August). Certain species, such as swifts and house martins, have adapted their nesting habits to take advantage of manmade structures; in particular older houses, cottages and barns. Swifts, for example, occasionally nest in rubble walls, and their nest sites are thus vulnerable to repointing, which might block up nest holes. By identifying such habitats at an early stage, it becomes possible to offset any damage or loss by, for example, leaving gaps in the pointing to encourage the continued use of the site by swifts.

Badgers Badgers and their setts are protected by law. Badgers have large territories and travel widely to feed. For this reason, even development at some distance from a sett can have implications for badgers. If your application affects a badger sett in any way, please contact the County Ecologist.

N.B. A variety of other plant and animal species are protected. A full list is contained at: www.ukbap.org. uk/lbap.aspx?id=454#5.

For further, detailed guidance, or if you are unsure about the status of a species, please contact the Species OfďŹ cer at English Nature on 01635 268881 or the County Ecologist on 01865 810469.

4 Development within existing settlements The settlements in the District are covered by Local Plan policies which describe the circumstances in which any development will be permitted. Most new development will occur in sustainable locations within the towns and larger villages where a wide range of facilities and services are already available. In the open countryside and the smaller villages, without a range of local services, new development will only be allowed in special circumstances, for example to meet an essential operational need or the conversion of existing traditional buildings.

Where development is permitted, the character and context of the site must be carefully considered before design proposals are developed. The character of the settlement will be determined by a complex series of interactions between it and the landscape in which it is set, including processes of growth or decline through history, patterns of change in the local economy and design or development decisions by landowners and residents.

As a result, the settlements of West Oxfordshire have a wide variety of scale, patterns, spaces and building types.

Some villages have a distinctive loose-knit form, allowing for a variety of views – both within the settlement and out over the countryside beyond. Others have an enclosed character with very limited views. Open spaces within settlements, greens, squares, gardens - even wide streets - contribute signiďŹ cantly to the unique form and character of that settlement.

West Oxfordshire Design Guide

4.1

Settlement pattern The towns and villages of West Oxfordshire exhibit four principal settlement patterns:

Nucleated Nucleated settlements are compact, with less dense development on the periphery of the central core.

Historically, the core may have been formed by a church or manor house (as at Stanton Harcourt).

The tight-knit form of nucleated settlements makes them particularly vulnerable to loss of character if development takes place beyond the fringes of the settlement.

Poly-Focal Poly-focal settlements have more than one original core or ‘end’. Historically, these may have developed around several manorial holdings or farmsteads some distance apart, subsequently attracting further development around them. In villages such as Great Rollright and Filkins later infill in the gaps has blurred the distinctions between the once-separate cores. Open land surrounding and penetrating between cores is a vital component of the character of poly-focal settlements.

Linear Linear settlements have a distinctive ribbon form, and develop along both main roads and the smaller side roads that branch off these routes. Development in linear settlements may only be a single house deep on each side (as at Long Hanborough) thereby allowing significant views into the landscape beyond. Recent development within linear settlements is often in the form of parallel closes, as at Over Norton.

Dispersed Dispersed settlements are characteristic of West Oxfordshire, with original manors or separate farm groups forming key elements. Around and between these groups accumulated loose patterns of cottages and scattered houses, (as at Combe and Wootton).

Open land is also a key component of dispersed settlements. Later infill can give a previously dispersed settlement a less gappy, and more nucleated form (as at Kingham).

4.2

West Oxfordshire Design Guide

Settlement location The settlements of West Oxfordshire are found in one of four principal location types:

Low-Lying/ Floodplain The low-lying or floodplain settlements are generally found in the Thames Vale character area. This landscape is open, expansive and flat, and the settlements here lie mainly between the 60 and 75 metre contours.

Natural constraints on development include rivers and manmade water courses, and the associated river floodplains (rather than factors relating to landform, such as steep gradients).

Enclosed/Valley The enclosed or valley settlements occupy the mainly open, rolling landscape of the Limestone Wolds, together with the Ironstone Valleys and Ridges and the Nothern Valleys and Ridges. All are visually contained by their topography. This containment takes one of three forms: river valley, as at Wootton; dry valley, as at Fulbrook; or bowl-shaped, as at Tackley. The settlements lie across contours on enclosed hillsides, but do not tend to spill over hill tops.

Hill Terrace/Spur The hill terrace/ spur settlements are generally located on open hillsides. This location type is not visually enclosed; rather the settlements tend to occupy open, flat hill terraces, and are contained within contours.

Growth can be linear, along a hillside as it is at Long Hanborough and Minster Lovell (Charterville); or more nucleated, on a hill spur, as at Churchill and Combe.

Open Wolds The open wolds settlements all occupy the Limestone Wolds character area, in landscape that is open, expansive and gently undulating. The settlements here are neither visually enclosed nor contained within contours; rather they range loosely over the landform.

The open wolds settlements vary greatly in elevation, with parts of Brize Norton lying below 80 metres; and parts of Enstone lying above 150 metres.

5 Buildings and their setting Buildings and landscape form two of the key elements of the physical environment. They can be organised in one of three general patterns. Two of these are traditional and familiar; the other is the result of twentieth-century processes, and has led in some cases to the creation of unsatisfactory visual environments.

The Rural System:

Landscape Containing Buildings

  

Here, the wider landscape provides the setting for the buildings: for example a house in parkland or a group of farm buildings in an agricultural setting. The buildings do not define space, but appear as objects in the landscape.

The Urban System:

Buildings Enclosing Space

In towns and villages, buildings enclose space to create a visually pleasing environment with a strong and distinctive ‘sense of place’.

Well designed enclosed spaces create the perception of safe and secure environments. The buildings themselves define public space: for example a street, alley, square or courtyard.

The Suburban System: The Unresolved Space

Here, the buildings are not contained within a clear landscape setting, yet are too loosely grouped, or are of insufficient height, to define and enclose space effectively. This ‘highway led’ approach has resulted in layouts with overly wide roads of arbitrary configuration and large areas of hard standing, which together form development that is wasteful of space and often lacking in identity.

West Oxfordshire Design Guide

5.1

Development density Development density can be thought of as a spectrum, ranging from the uninhabited rural landscape at one end to the built up town centre at the other, with intervening densities ranged between. In West Oxfordshire, six distinct levels of density can be identiďŹ ed.

The Open Countryside:

Isolated Rural Development:

Low Density Development:

The apparently natural landscape is actually the result of years of intervention by the local population. It consists of an intricate pattern of woods, ďŹ elds and pasture, cut through by rivers and tracks.

Boundaries and enclosures are formed by the manipulation of vegetation to form hedges, or from the extraction and use of available materials such as stone.

Isolated cottages or farm buildings are established features in the landscape.

They are located for reasons related to land holdings or agricultural activity.

Opportunities for new development of this type will be rare. Consequently, when they do occur they should receive an especially high degree of design attention to ensure that they are entirely appropriate to their setting.

Low Density development occurs at the edges of existing settlements or where settlements adjoin parkland or open space. Buildings may be grouped or free-standing; however, the landscape setting remains dominant. New development following these principles may be appropriate for the transitional zones between a settlement and the open countryside beyond.

New Rural (see pages 5.6 - 5.7) 5.2

West Oxfordshire Design Guide

Suburbia: Here, the buildings overwhelm the landscape context, but do so too loosely to enclose space properly. Although this type of development exists in the District, further development of this kind is not desirable.

Medium Density Development:

High Density Development:

This is the characteristic form of the centres of most villages and small towns in the District. Here, space is enclosed by mainly two storey blocks, which form a distinctive pattern of streets, lanes and irregular greens and squares.

The centres of the larger settlements in the District are generally formed by three and four storey buildings, grouped into informal blocks and bounded by the streets and urban spaces of the town. These central areas are characterised by mixed usage and have a distinctive urban atmosphere.

Design process and Design & Access Statements Design and Access Statements must accompany all applications for Listed Building Consent (other than internal works to domestic properties) and all planning applications in: Conservation Areas, Sites of Special Scientific Interest, The Cotswolds AONB and The Blenheim World Heritage Site.

Statements should not just describe the completed scheme, but show the ways in which the design has evolved through the processes described below, leading to the final proposals. The Statement must demonstrate how people of all ages and mobility will be able to use the buildings and places that are proposed. The Statement must show how the buildings and spaces will be arranged on the site, what they will look like, and how they will relate to their surroundings. It should be written in plain English avoiding jargon, and be succinct and well-illustrated. In addition, applicants for Listed Building Consent must be able to justify their proposals.

They will need to show why works which would affect the character of the listed building are desirable or necessary (PPG15). Full information to allow the assessment of the likely impact on the listed building and its setting must be provided.

Sources of guidance The general requirements for DASs are set out in paragraphs 56-110 of DCLG Circular 01/2006. This can be found at: http://www.communities.gov.uk/ pub/715/Circular0106DCLGGuidanceonChangestothe DevelopmentControlSystem_id1500715.pdf (The Circular recommends that applicants follow an assessment-involvement-evaluation-design process.

This closely mirrors the design process described below).

The CABE advice Design and Access Statements: How to write, read and use them can be found at: http://www.cabe.org.uk/AssetLibrary/8073.pdf Development proposals are generally based on a wish to change or adapt the environment. Proposals can range in scale from a small extension for an existing house to a major expansion of a town. These pages set out the principles which should be followed in preparing a design for a wide variety of situations. All schemes, even the most modest, should have a design brief which sets out the objectives of the proposals, explains the function of the new development, examines the cost implications, and identifies all of the potential sites and opportunities.

The ASSESSMENT of the site requires an accurate dimensional and levels survey of the land and buildings which are the subject of the proposals. It should also include information on the setting, the landscape context, any surrounding historic patterns of development, and local building styles and materials.

The assessment will identify constraints or limitations to development, such as archaeology, ecological protections, drainage or flooding issues, access, safety or traffic matters which have been identified. The extent of the surrounding area to be surveyed and the detail with which this is done will depend on the sensitivity and scale of the development. The physical, social and economic characteristics of the site and surroundings, the existing planning policies along with how people in the locality will be affected must be considered.

Issues relating to crime reduction can also be addressed by consulting with a police architectural liaison officer.

surroundings. DESIGN is a skilled process, and there is no substitute for the services of an architect or other appropriately qualified designer. Officers of the Planning Service will be pleased to offer advice or comment on proposals at this stage.

The final design drawings can be prepared when any problems identified at the sketch design stage have been resolved. The drawings typically include a location plan at 1:2500 scale, with a block plan at 1:200 or 1:500. Survey plans of the land or buildings affected and layout plans and elevations of the proposals should also be provided at 1:100. Applicants for planning permission should also demonstrate how they have taken account of the requirement for good design in their proposals, and a Design and Access Statement may be required to accompany your application.

Government guidance now encourages applicants to carry out professional consultations and COMMUNITY INVOLVEMENT at the earliest possible stage. Keep a record of the groups and people you have discussed the scheme with, and note the ways in which these discussions have directed or informed the design decisions.

Once the site’s context has been assessed, the local community and the right professionals have been consulted, identifying options for development should be a fairly simple task. EVALUATION of the information collected can now take place and any conflicting issues can be resolved.You should record what decisions have been taken and why. The evaluation will consider issues such as the suitability of the site to fulfil the brief, and any inherent benefits, constraints or hazards. Since this Guide recommends that new development should share some of the characteristics of the area in which it is located, design approaches based on the site context should be identified.

Initial sketch designs should now be prepared exploring ways in which the requirements of the brief can be achieved in relation to the inherent opportunities or constraints of the site and its

Housing density: general principles Measuring density There are a number of methods for measuring density: Dwellings per hectare is the most commonly-used measurement of development density. However, it is an unreliable indicator of the likely form of a new scheme; of the size of individual units or of the scheme’s impact upon local services. For example, the three schemes illustrated below share the same density dwellings per hectare measurement, but they differ radically in their appearance and character:

Net site density includes only those areas that will be developed for housing and directly associated uses.

This includes: i access roads within the site; ii private garden space; iii car parking areas; iv incidental open space and landscaping; v children’s play areas.

It excludes: i major distributor roads; ii primary schools; iii open spaces serving a wider area; iv significant landscape buffer strips.

Source: PPG3 (OPDM)

Plot Ratios: the total area of the building floor area x number of storeys/ area of the site Here, the volume of an individual unit, together with its footprint in relation to its building plot, is described.

In West Oxfordshire the following values represent the recommended maximum height and plot ratios for the three principal density types: Maximum Height

Maximum Plot Ratio

New Rural

2 Storeys

40%

New Urban (Medium)

Source: Andrew Wright Associates

Consequently, the density measurement of dwellings per hectare should not be taken in isolation as a guide to the form or quality of a residential development.

Furthermore, it should not be used as a tool for regulating urban design.

By incorporating further measures of development character - such as plot ratio and habitable room measurements - the form of the proposed scheme, the size of individual units and the scheme’s impact upon local services can be more usefully assessed.

5.6

New Urban (High)

Habitable Rooms per hectare: the number of rooms that people actually live in Here, a two bedroom house with one double and one single bedroom, a living room, kitchen and bathroom, counts as having 3 habitable rooms, as small kitchens and bathrooms are not included in the measurement. By using this, it becomes possible to assess in detail the effect of the scheme on the demand for local services (e.g. education, health, open space etc).

West Oxfordshire Design Guide

Through the use of a range of measurements of urban character, together with careful design, it becomes possible to ensure that the development is responsive to specific urban characteristics:

Density and local character Development density alone (dwellings per hectare) is a blunt and essentially limiting tool for the creation of distinctive areas of local character. A range of additional strategies, besides density, should be used in order to differentiate one area from another, and thus to establish and enrich local character. These strategies might include: • carefully responding to specific contexts within, or adjacent to, the development area (i.e. existing development, landscape, vegetation etc.); • creating a variety of building layouts within the scheme (differentiation of the arrangement of built forms);

A one acre scheme with ten five bedroom detached houses

• using specific building types to enhance local distinctiveness (differentiation of the built forms themselves; of the architecture and building materials); • distinctive non-residential provision; • differentiation of surface treatments and of road/ footway layouts; • differentiation of parking provision;

A one acre scheme with ten two bedroom detached houses

• differentiation of hard and soft landscaping, and boundary treatments.

Layout principles Many mid-twentieth century layouts feature cul-desacs surrounded by perimeter roads.

These tend not to create a sense of place and have no relationship with their surroundings.

Any new layout should be designed around a pattern of connected streets and public spaces that can be easily understood, so that people know where they are. The heart of a street network should focus on busy pedestrian places which have an identifiable and accessible location, defined by a concentration of facilities (e.g. shops, offices, small-scale workspaces, civic functions, schools, clinics, squares or parks) and by increasing building heights, providing greater enclosure.

Road layouts in residential areas often suffer from being too car-biased. In this illustration pedestrian desire lines take precedence over vehicle turning geometry. (Here the kerb corners are formed using ‘quarter cheese’ kerbstones).

In layouts with a more open character, some deflection of pedestrian routes may be permissible where, for example, a strong urban landscape character is proposed. In this illustration the road has been designed as an avenue or boulevard.

West Oxfordshire Design Guide

5.9

NEW RURAL The essence of the New Rural approach is that the buildings are contained within the landscape.

They do not, either through their scale or layout, overwhelm their landscape context. The success of such schemes depends on the careful integration of the development into its setting, so that the built and natural elements of the design together form a single, coherent design composition. This approach can be applied in a variety of contexts, from a single infill plot, to specific parts of large development areas. With infill plots the context for the building or buildings may already be well established. In such situations it is essential that the new design follows the existing spatial pattern.

Where the context is undistinguished or ambiguous, the opportunity may exist to create from new a distinctive New Rural character. The approach is particularly well suited to the fringes of larger developments, where it can provide a sensitive interface with the landscape beyond.

Layout In larger development areas and existing villages the layout is loosely structured, with buildings grouped informally or laid out in an irregular pattern behind verges, gardens or areas of landscape. Occasional buildings front directly onto the road. For smaller schemes or infill sites, the layout should accord with that already existing.

Building types The buildings may take a variety of plan forms, designs and styles, generally within the limitations of the evolved vernacular tradition. They are predominantly free-standing and of two storeys.

5.10

West Oxfordshire Design Guide

Pedestrian and vehicle routes The routes through New Rural schemes contribute to their distinctive character, and generally take the form of lanes of varying width with an informal alignment. This informality is not arbitrary, but depends upon topography, desire lines and the intensity of use. Routes are usually surfaced in materials that contribute to their informality, or that match those already existing. Smaller developments are served by shared use surfaces (i.e. with no footpath) and narrowed carriageways with passing places. Road layouts in larger development areas should constrain traffic speeds, and provide good links both within the site and into adjoining areas.

Landscape Since the essence of the New Rural approach is ‘buildings in a landscape’ the contribution of the landscape design to the overall scheme must be as great, if not greater than, the design of the buildings if this aspiration is to be met.

With smaller sites and infill plots, efforts should generally be made to retain existing features, such as trees and hedges. The West Oxfordshire Landscape Assessment contains details of the natural characteristics of the area, and the notes found in Chapter 3 of this Guide (‘Biodiversity and Landscape Character’) provide information on recommended plant species.

Landscape design is a key factor in the reinforcement of local character. In New Rural schemes, local tree and plant species should predominate. They play an important role by adding variety, affording privacy and containment, and providing a link between one house and the next. Although informal rural principles prevail, there may be opportunities for more formal planting arrangements, such as avenues.

Boundary treatments The boundary treatments in New Rural areas follow local patterns.Verges with hedges, or dry stone walls fronting gardens, form the main boundary treatments for development of this type within the District. In the case of infill sites, the careful design of boundary treatments is essential if the scheme is not to look out of place.

West Oxfordshire Design Guide

5.11

NEW URBAN; 1. Medium Density: The success of Medium Density schemes depends on the effective enclosure of space by the built forms. In the case of new development areas, the aim is to create a distinctive and easily understood environment with a traditional urban feel. This will generally be achieved with densities of between 35 and 55 dwellings per hectare (14 to 22 per acre).

Design cues, particularly in the case of smaller sites within an existing village or town, may be taken from the character and appearance of the area in which the development is located.

Layout In larger development areas, the built forms should generally be arranged to provide a coherent and clearly deďŹ ned pattern of streets, lanes, squares, courtyards and open space. Frontages should generally overlook the street, but may vary in their depth back from shared surfaces (though they should be no closer than a minimum of 500mm in order to avoid interference by porches, opening windows etc.) Parking may be in the form of garages or car ports to the sides of properties, courtyards located within the core of blocks, or by on-street provision. Courtyards, where used, are enclosed, providing direct and easy supervision from the surrounding houses, and may be accessed via narrow gaps in the street frontage.

Building types Detached, semi-detached and terraced forms predominate. Occasionally, three storey buildings can provide visual emphasis and serve as landmarks.Variation in building types, materials, scale, and architectural style, may be used to create visual interest and contrast. Given the increased proximity of buildings in Medium Density schemes, careful attention must also be given to the position, type and size of windows, and to internal room arrangements in order to ensure privacy.

Back to back distances must provide adequate privacy between habitable rooms.

5.12

West Oxfordshire Design Guide

Pedestrian and vehicle routes Routes through Medium Density developments should have a high degree of visual legibility, and provide a permeable network linking the scheme both to local amenities and to surrounding areas.

The pattern of streets provides direct, safe and attractive routes for pedestrians, cyclists and drivers.Variations in direction and alignment of streets create an evolving and varied townscape, whilst promoting safety by slowing drivers. The main streets are bounded by footways and have a recognisable character that is well defined by the clear building lines. Side streets and lanes provide additional permeability. They should have a subtly different character to the main streets and may feature shared surfaces. Road layouts should cater for all users, not just motor vehicles. Pathways should be carefully designed to avoid ‘dead spaces’, unrestricted public access to the rear of properties and other opportunities for criminal activity.

Landscape Well-designed open spaces should be obviously useful and visually appealing. Grassed parktype spaces provide areas of soft landscaping that add variety, character and amenity to new development. Expected open space provision in development areas will be based upon an assessment of existing provision. Play areas are an important amenity and should also be well designed, visually appealing and easily accessible.

Trees and vegetation can have a significant role in defining and enclosing space in Medium Density schemes and can have a marked effect on their character. Trees and planting should be used both as formal elements to line squares or streets, and informally in green spaces or back gardens. They can be used to ‘soften’ the streetscape and to reduce the visual impact of parked cars.

Boundary treatments Front boundaries are enclosed by elements from an urban palette, including railings and walls. Gaps between buildings are kept to a minimum and are generally close by walling. Where gaps do occur (e.g. for access to a courtyard) the entrance is designed as an integral part of the streetscape.

West Oxfordshire Design Guide

5.13

NEW URBAN; 2. High Density: High Density layouts are appropriate for the centres of larger new developments, or for the extension of existing centres. Schemes of this kind serve as the physical and social centre of the surrounding area. The design should create a highly attractive, marketable and prestigious environment which will encourage high levels of social activity.

High Density areas should contain both a high concentration of non-residential provision, such as shops, pubs, schools, nurseries, community buildings and public transport links, together with the highest residential densities – typically, in the range of 40 - 75 dwellings per hectare (16 - 30 per acre).

Layout In High Density areas the blocks may be significantly taller and larger than those of Medium Density areas, and may be of mixed use. They should feature a high concentration of entrances that open directly onto the street. The High Density and mixed use qualities give rise to issues of privacy, amenity, access and parking; all of which must be carefully addressed and resolved during the design process.

The blocks in High Density areas are arranged to provide a clear streetscape with a strong ‘sense of place’. Building frontages are generally directly related to shared surfaces, or footways. Servicing, parking and rear access to properties is provided by enclosed courtyards accessed through designed openings in the street frontages. The mainly residential use of upper floors of the buildings promotes good visual supervision of the streets, squares and courtyards below.

Building types The buildings should generally be 2½ - 3½ storeys (with significant variation in roof type to provide visual interest). Taller buildings can be prominently sited as landmarks. A wide variation in buildings types, materials, and architectural styles may be used to create visual interest and contrast.

5.14

West Oxfordshire Design Guide

Pedestrian and vehicle routes The pattern of routes and spaces should be legible, permeable and provide feelings of safety and well-being. The pattern should draw people together in a friendly and attractive environment.

There must be space for public events, markets, art and performances. Streets should generally radiate out from the centre with a clear priority given to pedestrians in the central area. Roads that form direct routes into the core should be distinct from the minor routes skirting the centre.

The form of the development should be dictated by urban design criteria and then ‘plumbed in’ for traffic circulation. Provision for rear and courtyard servicing should be carefully designed; particularly for retail and community uses. The distinction between public and private spaces must be clear and well defined. Pedestrians and cyclists must be able to move freely through all parts of the layout, with readily accessible parking available to different types of users at different times of the day. Pathways should be carefully designed to avoid ‘dead spaces’, unrestricted public access to the rear of properties and other opportunities for criminal activity.

Landscape To complement the character of the area, the landscape treatment should have a strongly formal urban quality. For the pedestrian realm, a landscape palette of the highest quality, incorporating a carefully considered blend of landscaping elements (both hard and soft) together with a coordinated approach to street surfaces and furniture, lamps, seats, bins, paving and signs is of profound importance. Street trees should form a major element to enhance public areas and to provide softening effects and focal points.

Boundary treatments Front boundaries are enclosed by complementary elements from the chosen urban palette, including railings and walls. Gaps between buildings are kept to a minimum and are generally closed by walling. Where gaps do occur (e.g. for access to a courtyard) the entrance is designed as an integral part of the streetscape and is kept narrow.

Rather than forming a strong and continuous edge (see New Urban case study 2) here the houses merge softly into, and are contained by, the landscape. The retention of mature existing planting has reduced the scheme’s impact on the wider landscape, and softened the visual transition between the two.

The scheme, within the Conservation Area, required a detailed understanding of the historical context, and a series of carefully-judged interventions in order to re-assert something of the area’s original character and meaning.

1

Fundamental to the coherence of the scheme was the opening up of the hotel archway. This was blocked up in the 20th century and originally gave access to the stabling and galleried range to the rear.

2

The contrast between the monumental, open hotel frontage, and the narrow intimacy of the plot extending behind the hotel, could not be more pronounced. Surface treatments play a key role here: this was originally an enclosed courtyard space, rather than a through-street.

9 Sustainable building design Although the earth’s climate is in a state of continuous natural change, most scientists agree that the speed and intensity of this change is largely due to human activity, and in particular the heavy use of coal, oil and natural gas. There are two main problems with the use of fossil fuels. Firstly, by-products of the burning of these fuels, such as carbon dioxide, concentrate in the atmosphere and lead to global warming. Secondly, fossil fuels represent a fast diminishing natural resource.

The solution to both of these problems is to reduce the reliance on fossil fuels; both by being more energy efficient, and by finding alternative and renewable sources of energy. Although climate change is a global problem, there is a widespread recognition that action taken at the local level has important consequences for global well-being.

Sustainable building design will help to reduce greenhouse gas emissions and enable adaptation to climate change. It is an important step towards Sustainable Development - now a statutory duty for local authorities, enshrined as ‘the core principle underpinning planning’ (PPS1). Recent revisions to UK Building Regulations Part L (energy efficiency) require a 20% improvement in current energy standards in buildings: this has profound implications for design.

A sustainable building is one that: • minimises the use of scarce resources such as certain building materials, fossil fuels and water; • is economic to run over its whole life cycle and fits well with the needs of the local community; • is energy and carbon efficient, designed to minimise energy consumption, with effective insulation, heating and cooling systems and appliances; • values and sustains or improves existing site character, topography, vegetation, watercourses and built features; • minimises the need for unsustainable transport and encourages travel by cycle or on foot; • minimises the production and costs of waste disposal, and which looks to re-use on-site materials such as waste soil; • minimises flooding and pollution; • is designed to make recycling and composting easy for its occupants.

Sustainable building design principles should be considered at the beginning of the design process, as some features - such as Passive Solar Design - cannot be retro-fitted. This chapter sets out sustainable building design considerations for the following elements of the design process; site and layout, buildings and building materials.

Madley Park, Witney

West Oxfordshire Design Guide

9.1

The site and layout

Location and setting

Energy saving layout design

Traditional buildings in the District were generally located in sheltered rather than exposed locations and were thus easier to heat. They were close to primary resources such as water, with easy access to the work of the occupants.

The siting and orientation of buildings relative to the existing landscape (together with the treatment of that landscape) can save up to 30% in cooling and heating costs. The amount of direct sun heating up surfaces can be reduced, and reected light prevented from carrying heat into the building from the ground or other surfaces. It can also reduce wind velocity and slow air leakage from the house.

Development in a sustainable location both beneďŹ ts from and supports existing local services and infrastructure, and is thus less reliant on fossil fuels than is development remote from local services.

The Local Plan embodies the principles of sustainable development by locating most new development in the largest settlements in the District, where the need for travel to local services and infrastructure is minimised. Within development areas, layout design should be as cycle- and pedestrian-friendly as possible, to further encourage reduced reliance on travel by car.

A sustainable development approach is one which values and sustains or improves the character of the site. Existing features, such as topography, vegetation, watercourses and built structure should be retained wherever possible. Inert materials which arise from the development should, in the ďŹ rst instance, be retained and re-used on the site, not disposed of elsewhere.

To maximise solar gain, the majority of housing within a layout would need to face within at least 45 degrees of south, and preferably within 30 degrees.

Overshadowing by neighbouring buildings and trees should reduce the loss of useful total solar gain by no more than 5% (through the spacing and location of dwellings rather than the loss of existing trees).

Maximising solar gain at the layout design stage also maximises the potential for solar power generation (which may be added to the scheme at a later date).

In general it is both easiest and most cost-effective to incorporate sustainable energy strategies such as Combined Heat and Power (CHP) and Geothermal Energy - at the design layout stage.

During summer months, shade created by trees, together with the effect of grass and shrubs, will reduce air temperatures adjoining the house, and provide evaporative cooling. As people may spend more time outside, natural shade becomes more important. Deciduous trees on the south side of a property can be used to admit the winter sun; evergreen plantings on the north side can slow winter winds. Planted channels can funnel cooling summer breezes into a property.

Careful evaluation of existing vegetation will identify those species that can contribute to an energy conserving landscape. Established plants should be retained wherever possible as they will require less effort to maintain, and will generally be larger and better established than new plantings.

See below for detailed information on Passive Solar Design (PSD).

9.2

West Oxfordshire Design Guide

Sustainable landscapes and open space Increasing average temperatures will lead to a greater demand for outdoor spaces (both public and private) and existing spaces will be used more intensively with lifestyle changes. Although predicting such changes is difficult, the experience of those living in warmer climates can give us some clues.

As outdoor spaces are used more, there will be a need for more hard wearing natural surfaces.

Landscaping that mimics Mediterranean marquis or lowland heath land for example can be hard wearing and appropriate to an urban environment.

Alternatives to traditional lawns may be needed for hotter, drier summers. Gravelled or paved areas can be used as an alternative to lawn (as long as a high proportion of permeable surfaces - to avoid aggravating soil erosion and run-off - can be provided). However, it should be remembered that lawns are highly valuable in biodiversity terms.

Changes in temperature and water balance can have significant implications for soil, and require the careful planning of green spaces. For example, increased water storage can reduce flooding and subsidence. Other strategies, such as the increased vegetation required for Sustainable Drainage Systems (SUDS) must not be at the expense of soil condition (by for example allowing subsidence).

Adapting to climate change, a landscape checklist: • Provide deciduous vegetation to give summer shade, taking care that the foundations of nearby buildings are sufficient to prevent movement; • Introduce soil management strategies to protect against flooding and subsidence; • Water in water features should be recycled or re-used, for example for watering vegetation rather than putting into drains; • Solar energy can be used to power pumps to recirculate water in water features; • Provide wormeries for compostable waste (although this is only applicable at the domestic scale). Large scale composters could be considered for business/industrial operations; • Incorporate an appropriate range of public and private outdoor spaces in developments, with appropriate shade, vegetation and water features; • Ensure the design of surfaces takes account of increased use, permeability and the potential for causing dust and soil erosion; • Consider gravelled or paved areas rather than lawns (so long as a high proportion of permeable surface can be provided); • Ensure the selection of vegetation takes account of future climate change; • Provide rainwater collection/ grey-water recycling for gardens and landscaped areas.

West Oxfordshire Design Guide

9.3

The site and layout

Surface water and Sustainable Drainage Systems (SUDS)

Biodiversity Many local plant and animal communities enjoy statutory protection and those found on or adjacent to the site must be conserved at all stages of construction. Planning Conditions, Statute, and Construction Codes and Standards must be adhered to at all times, and damage to trees and contamination or pollution from oil or chemicals must not take place. There is a need not only to conserve biodiversity, but to seek net gains in biodiversity as a result of new development (see chapter 3).

SUDS (sustainable drainage systems) mimic natural drainage patterns and can ease surface water runoff (so encouraging the recharge of groundwater) and can help to avoid soil erosion. SUDS represent a drainage strategy that should be considered on all sites. SUDS include rainwater harvesting, green roofs and water butts; ďŹ lter strips and swales (vegetated landscape features with smooth surfaces and a gentle downhill gradient to drain water evenly off impermeable surfaces).

SUDS can also provide signiďŹ cant amenity and wildlife enhancements, as well as pollutant trapping and degradation processes (this secondary use must not compromise the system’s primary role as a drainage system). Soakaways and permeable and porous pavements avoid aggravating run-off and allow water to drain directly into the ground (though the primary purpose is the conveyance of water away from buildings). In practice, all pavements, driveways, footpaths, car parking areas and access roads could have permeable surfaces.

Sustainable energy

Waste and recycling

In the UK five sustainable technologies in particular offer viable alternative means of energy production: Solar (see p 9.7), Wind, Ground Source Heat Pumps (GSHP), Biomass and Combined Heat and Power (CHP see Waste & Recycling). The scale and density of a development can have a huge impact on the viability of sustainable energy schemes. (For example, CHP schemes are far more viable at higher densities, while biomass systems can be better suited to rural locations). Renewable energy measures should not be taken at the expense of landscape character or the quality of the built environment.

The Council operates a waste collection service that includes the provision of bins for general waste, and containers both for glass and for paper/ card/ plastic and tin. Collection is from the kerbside, but also from communal bin stores or other specified collection points. Waste and recycling provision has profound implications for site layout, and must be considered at an early stage in the design process.

Wind energy The UK has 40% of Europe’s total wind energy, but this is largely untapped and only 0.5% of our electricity requirements are currently generated by wind power. Wind-flow must first be assessed to gauge viability. For planning permission, visual impact (across West Oxfordshire generally, but in the Cotswolds AONB specifically) will form a key environmental consideration. Further information: www.bwea.com and http://www.lowcarbonbuildings. org.uk/micro/wind/

Ground Source Heat Pumps (GSHP) Heat pumps transfer heat from the ground into a building (via buried pipework) to provide space heating and, in some cases, to pre-heat domestic hot water. For every unit of electricity used to pump the heat, 3-4 units of heat are produced. Air source and water source heat pumps are also available. Further information: http://www.lowcarbonbuildings.org. uk/micro/ground/

Wormeries for compostable waste can be provided (although this is only applicable at the domestic scale). Large scale composters could be considered for business/ industrial operations. Rainwater collection/ grey water recycling systems can be used for watering gardens and landscaped areas. Detailed guidance on waste and recycling provision, bins and bin stores, can be found in Appendix 17.

Combined Heat and Power (CHP) With CHP one of the by-products of power generation - namely heat - is recycled for a variety of purposes, including community heating and space heating. Because it uses what is typically waste heat in order to heat buildings it can increase fuel efficiency to 70-90% (compared to the 30-50% with conventional generation). CHP is especially suited to larger community heating schemes. Further information: www.chpa.co.uk

Biomass energy Biomass is organic matter of recent origin. The CO2 released when energy is generated from it is balanced by that absorbed during the fuel’s production. The process is thus carbon-neutral.

Biomass is also called ‘bio energy’ or ‘bio fuels’. Bio fuels are produced either directly from plants or indirectly from industrial, commercial, domestic or agricultural products. Further information: http:// www.lowcarbonbuildings.org.uk/micro/biomass/ and www.tvbioenergy.co.uk

West Oxfordshire Design Guide

9.5

The building

Building aspect

Passive Solar Design

Building form, room arrangements and the location of doors and windows in relation to the path of the sun and prevailing winds can have a significant impact on the resources needed for heat and light. For example, a building with its living rooms on the warmer south, south-east or south-west sides could exploit opportunities for large window areas on these walls to maximise natural lighting. By contrast, room functions on the cold and shady north side could take advantage of these conditions for cool storage, services, or to draw in cool air. Window sizes can be smaller on the cold side to reduce heat loss.

Passive Solar Design (PSD) makes use of the sun’s energy for heating and cooling living spaces. Further information on PSD can be found at: http://www.greenbuilder.com/ sourcebook/PassiveSol.html.

The layout of new development should balance the benefits of minimising heat loss in winter with the risk of excessive solar gain during the summer. The site layout should take advantage of landform and landscape for shelter to minimise heat losses in winter and provide adequate shade in summer. For example, deciduous trees help minimise heat loss but also provide shading in summer but lower sun angles permit solar gains in winter.

9.6

In the case of Passive Solar Heating, the goal is to capture the sun’s heat within the building’s elements and release that heat during periods when the sun is not shining. The principal features of Passive Solar Heating are south facing windows and Thermal Mass.

The building envelope should be designed to benefit from passive heat in winter, but reduce heat gain in the summer. Summer heat gains can be reduced by lighter or more thermally reflective surfaces, especially roofs. Passive Solar Cooling makes use of natural ventilation, and typically employs such elements as openable ventilation windows, wing walls and thermal chimneys.

Openable windows can aid natural ventilation when located in the path of prevailing summer breezes. Wing walls are vertical exterior wall partitions placed perpendicular to adjoining windows, which enhance ventilation through windows.

Thermal chimneys create or reinforce the effect of hot air rising, in order to draw air out of buildings and induce air movement for cooling purposes.

West Oxfordshire Design Guide

Thermal capacity and insulation Thermal Mass refers to materials, such as masonry and water, which can store heat energy and be used to prevent rapid temperature fluctuations.

Traditional local stone buildings have thick walls of substantial mass and high thermal capacity: they heat up and cool down slowly, insulating the residents from rapid thermal variations.

Modern buildings, by contrast, have thin walls and low thermal capacity. To address this, Buildings Regulations require high levels of thermal insulation.

The structure should have the optimum Thermal Mass for a comfortable internal environment with the least use of energy.

For high occupancy uses (e.g. houses and hospitals) this usually means high thermal mass. Many types of insulation are made using processes which produce toxic waste and gasses, or are manufactured in other parts of the world, leading to heavy energy use in transportation. It is worth considering local natural insulation, such as wool batts, which are produced from the byproducts of textile production.

Solar panels

Convection ventilation

Despite the UK’s cool climate, solar energy still represents a highly viable means of sustainable energy production. The sun’s energy can be harnessed in two main ways: by using photovoltaic (PV) panels, which utilise light to produce electricity; or by using solar powered heating panels, which directly heat water. Solar technology is well-established, with a wide range of products on the market. Panels can be linked in almost inexhaustible configurations, and for optimum performance should be located on south-facing, unshaded roof aspects.

Natural processes can be exploited to provide free ventilation. Since hot air rises, cool fresh air may be drawn into a building at low level on the shady side. When heated by solar gain from south facing windows air will be drawn upwards and vented naturally at high level, helping to draw in more fresh air at low level. Atria, conservatories and porches can be used to enable natural ventilation and the conservation of heat.

Further information: www.est.org.uk/solar/index_ solar.html

Higher temperatures may lead to pressure for mechanical ventilation and cooling to be added to buildings in the future, even if not installed initially.

Developers should consider using alternative methods to traditional air conditioning so that comfortable temperatures can be maintained while minimising additional greenhouse gas emissions. Larger floor-toceiling heights will generally help in allowing later addition of any cooling mechanisms. Higher ceilings trap hot air above the heads of people using the room, making the room feel cooler.

West Oxfordshire Design Guide

Re-use or conversion of existing buildings The re-use or conversion of existing buildings takes advantage of the high levels of embodied energy in their fabric.

This would be lost in demolition and redevelopment; processes which themselves would use even more energy.

It was thought until recently that the embodied energy content of a building was small compared to the energy used in operating the building over its life. Most effort was therefore put into reducing operating energy by improving the energy efficiency of the building envelope. Research has shown, however, that this is not always the case. Embodied energy can be the equivalent of many years of operational energy. Consequently, buildings should be designed for long life and adaptability, using durable, low maintenance and easily separable materials. Avoiding an overly large house will also save materials.

Detailed information on the reuse or conversion of existing agricultural buildings can be found in Appendix 8.

9.7

Building materials

Timber

Local materials

The UK is currently the largest importer of illegal tropical timber in Europe, with approximately 60% of all UK tropical timber imports coming from illicit logging operations in some of the world’s most important rainforests.

The use of locally-produced sustainable materials reduces energy use in transport, and promotes local enterprise and employment. By contrast, many cheap products are manufactured in other parts of the world, and because of large energy inputs in transport, cannot be seen as sustainable (information on local procurement can be found at:. www.futurefoundations.co.uk/ charter/08_neighbourhoods.php).

Due to an increase in the design of ‘green’ buildings, and the promotion of timber as a renewable resource, the use of timber within the construction industry is likely to grow. As a result of this increase in demand there is also an increased likelihood of illegal logging, poor forest management and deforestation.

Timber used in construction should be drawn from sustainable sources. The CIOB (Chartered Institute of Building) ‘Procuring Legal and Sustainable Timber’ guide explains the procedures that need to be adopted by construction organisations to achieve these environmental objectives: www. constructionbooksdirect.com.

9.8

Embodied energy is a method of factoring in all the hidden energy costs of producing a material.

This gives a truer cost of the building material. Some general estimates of embodied energy for various materials (the higher the number the higher the environmental ‘cost’): Material Timber Brick Glass Steel Plastic Aluminium

Embodied Energy 1 2 3 8 30 80

West Oxfordshire Design Guide

Manufactured materials and pollution Many modern building materials and products are manufactured using very high energy inputs and processes which produce toxic waste and gasses.

PVC is excluded from the EU’s and WWF-UK’s purchasing policies because it contains phthalates and releases highly toxic chemicals when incinerated. PVC is not a sustainable material and will degrade with exposure to ultraviolet light.

As a general rule, the sustainable designer should avoid materials which emit formaldehyde, organic solvents,VOCs and chloroflourocarbons, which contribute to the recent ‘sick’ buildings phenomenon.

Most finishes and adhesives contain VOCs which ‘outgas’ and adversely affect indoor air quality. Lower VOC and nonVOC products are available.

Low biocide paints avoid the fungicides and mildewcides typically added to latex paints to extend their shelf life. These additives are potentially harmful to indoor air quality. Natural plant/mineral-based finishes and adhesives are available from several companies (such products can cost more and can spoil if not used quickly). Some very energy-intensive finishes, such as paints, often have high wastage levels.

Re-use of materials

Water services

Wind and rain

Efforts should always be made, where possible, to re-use and refurbish rather than demolish or replace.The re-use or recycling of manufactured building materials, such as brick, timber or slate, is highly sustainable because it reduces the strain on natural resources and eliminates the need for new energy investment.

The supply of water is likely to become more restricted because of climate change, while the demand is likely to increase. Initiatives such as ‘Water Cycle Management for New Development’ (www.wand.uk.net) should be considered as part of project design, implementation and management.

Materials that are local, and that have a high recycled content and low embodied energy should be favoured, and preference given to materials manufactured using renewable energy sources.

Standard sizes should be specified; the use of energy-intensive materials as fillers should be avoided; off-cuts, construction waste and materials arising from demolition should be re-used or recycled.

The use of water from the mains should be minimised. New homes should be built to the highest practicable BREEAM Ecohomes standards with regard to reducing internal water use. Further information can be found at: www.breeam.org/

Climate change is likely to result in stronger winds and heavier rain, so roof and local drainage systems must be designed to cope with the increase. Loose items, such as roof tiles, may need to withstand higher winds, while rain may be driven harder against walls and roofs.

The design of openings and the choice of materials must allow for this.

Redundant structure should be avoided, and efficient building envelope design and fittings used in order to minimise materials use. Materials that can be re-used or recycled easily at the end of their lives using existing recycling systems should be favoured.

Strategies to minimise water use include water efficient toilets (and waterless urinals), taps, showers, dishwashers and washing machines, as well as the installation of water re-use systems.Water saving can also be promoted by installing water meters.

Rainwater should be harvested for irrigation, garden watering (in butts), car washing or toilet flushing. Such systems reduce household water demand, ease pressure on the mains water supply, and can reduce the risk of flooding by storing rainwater and buffering run-off.

The risk of flash-flooding will also increase, while at the same time Building Regulations now require level thresholds for disabled access. Both of these factors increase the risk of ingress of water at ground level.

The size of guttering and down pipes could be increased. The use of secret and parapet gutters and internal down-pipes should be reduced. Water could be thrown clear of buildings using spouts and gargoyles, and storm drains on the ground. In areas of low flood risk, the size of upstands could be increased.

Targets for water consumption: Housing - 30 cubic metres per person per year; Offices - 1.05 cubic metres per person per year.

Listed Building Consent is required for any work that will affect the character or appearance of a Listed Building or structure, either externally of internally, regardless of that building’s grade. Demolition, extensions, and internal or external alterations all require Listed Building Consent. The administration of Listed Building Consent is the responsibility of the District Council, and applications for Listed Building Consent should be made on forms available from the Planning Service.

Listing gives statutory protection to buildings deemed to be of special value because their age, rarity, architectural merit or method of construction. It protects these buildings from unauthorised alteration or demolition.

There are roughly 500,000 listed buildings in England.

The older a building is the more likely it is to be listed.

All substantially complete buildings built before 1700 are listed, as are most of those built between 1700 and 1840. After 1840 the criteria become tighter with time, so that post-1945 buildings need to be of exceptional importance to merit inclusion.

Listed Buildings comprise a small but immensely important part of the building stock of West Oxfordshire. They serve as examples of local building types from the 12th century to the present.

Included are buildings of the evolved vernacular tradition, together with those influenced by national or international styles, including Gothic, Jacobean, Classical, Georgian,Victorian and 20th-century design.

Listed Buildings provide examples of technology and innovation in construction. A unifing theme in West Oxfordshire is the use of local materials; including most notably limestone and ironstone, longstraw thatch and stonesfield slates, lime mortars, renders and limewashes. Despite historic imports of brick, tile and slate, local materials predominate.

Proposals for new listings can be made to: English Heritage Eastgate Court 195-205 High Street Guildford GU1 3EH Tel: 01483 252000 Email: General enquiries: southeast@english-heritage.org.uk For listing enquiries: hpoperations@english-heritage.org.uk Visit: www.english-heritage.org.uk

Unauthorised external or internal work carried out to a Listed Building is a criminal offence that may lead to prosecution or enforcement action, and ultimately an unlimited fine or up to twelve months imprisonment (or both). There is no time limit for this action, and liability for illegal works may pass to the new owners of a Listed Building.

Anyone wishing to redevelop a site on which a Listed Building stands will need both Listed Building Consent for the demolition and planning permission for the new building. Planning permission alone is not sufficient to authorise demolition. Similarly, anyone wishing to alter a Listed Building in a way that would affect its character, and whose proposed alteration amounts to development for which specific planning permission is required (as distinct from a general permission given by the General Development Order), will also need to apply for Listed Building Consent.

Applications for Listed Building Consent should be accompanied by survey drawings recording the existing form of the building. The survey drawings should adhere to Architectural Drawing Conventions set out in ‘Recording Historic Buildings’ RCHME 1991 ISBN 1 873592 04 3. Proposed alterations to Listed Buildings for which consent is sought should be clearly shown on proposals drawings which make a clear graphic distinction between existing retained building fabric, demolitions and new work. Applicants for Listed Building Consent must be able to justify their proposals.

They will need to show why works which would affect the character of the listed building are desirable or necessary (PPG15). Full information to allow the assessment of the likely impact on the listed building and its setting must be provided.

There are approximately 3,200 Listed Buildings in West Oxfordshire. A copy of the List of Buildings of Special Architectural or Historic Interest is available for inspection at Planning Reception. Listed Buildings fall into one of three categories:

Grade I (2% of Listed Buildings nationally) These buildings are of exceptional national importance.

There are 43 in West Oxfordshire, including Blenheim Palace (which also forms part of a World Heritage Site), Cornbury Park, Chastleton (pictured right), Kelmscott Manor and many of the district’s ancient parish churches.

Grade II* (4% of Listed Buildings nationally) Buildings of outstanding interest. There are 211 in West Oxfordshire, including many of the best examples of the local variety of Cotswold architecture; for example, Strong’s House in Taynton, and Wychwood Lodge in Ramsden. The agricultural and industrial heritage of the District is also well represented by Church Enstone Tithe Barn, the Blanket Hall in Witney and Bliss Tweed Mill in Chipping Norton.

Grade II (94% of Listed Buildings nationally) Buildings of special interest. There are 2934 in West Oxfordshire. These form key elements of the historic character of the settlements and landscape of West Oxfordshire, and range from grand houses to simple cottages, farm buildings to factories, telephone boxes to milestones.

Appendix 3 - Scheduled Ancient Monuments Scheduled Ancient Monuments are nationally important archaeological sites protected by the Ancient Monuments and Archaeological Areas Act 1979. The Department for Culture, Media and Sport is responsible for the Act, and is advised by English Heritage. Scheduled sites include standing structures such as crosses, barns, bridges and dovecotes.

In West Oxfordshire there are 142 Scheduled Ancient Monuments, including well known sites, such as the Rollright Stones and Minster Lovell Hall, as well as comparatively recent monuments, such as a 19thcentury pottery factory near Leafield.

Scheduled Monument Consent (SMC) Scheduled Monument Consent is required before works can be carried out which might involve any of the following: demolishing, destroying, damaging, removing, repairing, altering, adding to, flooding, or covering over the monument. If the land is being used for agriculture, consent is also required for the following: ploughing at a greater depth, sub soiling, drainage, planting and uprooting of trees, or other works below previous plough depth. Scheduled Monument Consent is also required for any archaeological excavation.

Applying for Scheduled Monument Consent The application form can be downloaded from the website of the Department for Culture, Media and Sport, or requested by phone or post: Visit: www.culture.gov.uk/historic_environment/ Scheduled_Ancient_Monuments.htm Department for Culture, Media and Sport Historic Environment Designation Branch 2-4 Cockspur Street London SW1Y 5DH Tel:

How Scheduled Monument Consent affects other types of permission

Breaches of Ancient Monuments legislation: the penalties

Applicants for Scheduled Monument Consent must investigate if planning permission is also required.

However, if a structure is both Scheduled and Listed, Scheduled Monument Consent takes precedence, and Listed Building Consent is not required.

It is an offence to begin work of any description before Scheduled Monument Consent has been formally granted. The penalty for carrying out prohibited work is punishable by ďŹ nes of up to ÂŁ5,000. It is now an offence for anyone to use a metal detector on a monument without premission. A further, more serious offence is to remove, without permission, an object found by a metal detector on a Scheduled Monument.

Scheduled Monument Consent is not required: 1. If the site of a Scheduled Monument is farmed and the work involved has remained unchanged for the last ďŹ ve years; 2. For works URGENTLY necessary in the interests of health or safety, subject to notice to the Department for Culture, Media and Sport; 3. In cases of special urgency requiring immediate action. The Department for Culture, Media and Sport MUST be informed as soon as the works have been carried out.

Appendix 4 - Conservation Areas Conservation Areas are places of special architectural or historic interest, which have a particular character or appearance worthy of preservation or enhancement. Groups of buildings (both listed and unlisted), walls, trees and hedges, open spaces, views, and the historic settlement patterns all combine to create an individual sense of place. It is this character, rather than the individual buildings, that Conservation Area status seeks to protect. The ďŹ rst Conservation Areas in the District were identiďŹ ed in the late 1960s.

Since then, there has been a rolling programme of designations. There are currently 49 Conservation Areas in West Oxfordshire. Conservation Areas are designated under the provisions of Section 69 of the Planning (Listed Buildings and Conservation Areas) Act 1990.

Today, a wide range of architectural forms and synthetic materials are available. These, when juxtaposed with traditional forms and natural materials, are often inappropriate. Unless special care is taken in both the design and the choice of materials for new buildings the character of our historic settlements will be progressively eroded and ultimately lost to future generations.

Effects of Conservation Area designation The designation of a Conservation Area does not imply that no further development or change will take place. However, where new building is to be allowed, it ensures that it is fully in sympathy with the character of the area; either by making a positive contribution to the area’s character or appearance, or by leaving the character or appearance of the area unharmed. In Conservation Areas, the preservation and enhancement of the area is a consideration in all planning decisions.

Planning applications made for development should show how the proposals will preserve and enhance the character of the area, and should demonstrate that the proposals are sympathetic to their surroundings.

Special attention should be given to design, scale and use of materials, so that the existing character of the area is not damaged.

The historic settlements of West Oxfordshire owe much of their charm to the consistent use of local materials (most notably oolitic limestone) and the unfolding pattern of historic building styles. Buildings appear to have grown together organically, creating a visual context into which new development must be sensitively inserted if it is not to damage the appearance of the existing settlements.

Listing and Conservation Areas Listed Building Consent is required for any alteration that affects the character or appearance of a Listed Building. Demolition, extensions or internal or external alterations, all require consent regardless of the grade of the building (i.e. grade I, grade II* or grade II). It should also be remembered that within Conservation Areas many other buildings and structures, though not listed in their own right, can nevertheless combine to form an environment of charm and historic character.

Development Control advice

Trees

The demolition of most unlisted buildings in a Conservation Area is controlled, and ‘Conservation Area Consent’ is usually required for work of this kind.

Some ‘permitted development’ rights are restricted within Conservation Areas. These rights allow certain types of development to take place without planning permission (for details, please contact West Oxfordshire District Council).

Owners of trees in the Conservation Area must give six weeks notice to the District Council before lopping, topping or felling. This applies to trees with trunks more than 75mm in diameter, but not to fruit trees or saplings.

The West Oxfordshire Local Plan contains policies for development in Conservation Areas. Within Conservation Areas the existing buildings, land uses, historic settlement patterns and open spaces should remain largely undisturbed. Where development is acceptable, the following advice is offered in relation to Policies BE5, BE5A & BE6.

Extensions to existing houses and the conversion of appropriate structurally sound buildings, which are worthy of retention or make a positive contribution to the local scene, will also be allowed in some circumstances.

New buildings and extensions should be well designed in themselves, and in sympathy with the character of the area. They should respect the form, siting and scale of the surrounding buildings. New development should incorporate, where appropriate, existing features of importance, such as trees, hedgerows, ponds, stone walls, paths and tracks.

Views into and out of the Conservation Area, as well as views within the settlement itself, should be carefully assessed. New development should be designed to ensure that these are not harmed.

The conversion of redundant historic buildings should respect the original character of the building and its setting. Historic or architectural features of merit should be protected or retained. Large extensions, or an accumulation of extensions, can easily obscure the simple form of traditional buildings and should be avoided. Some buildings with a particular visual or historic character may be harmed by new development, however well designed. In these cases development may not be allowed.

A4-2

Trees and hedgerows which make a contribution to a Conservation Area should not normally be removed unless dead or dangerous. Where removal is necessary, suitable replacements should be planted, as discussed with the Planning Department.

Conservation Area Character Appraisals Conservation Area Character Appraisals are concise, illustrated documents designed to describe the main features of a given Conservation Area which contribute to its special interest and quality. The documents are intended to provide information for local residents, planners and developers, and to provide an internal resource for the District Council.

Each document has sections describing the location and setting of the Conservation Area; the historical development, settlement pattern, architectural character, boundary treatments, landscape and views; and includes a catalogue of the listed buildings together with a map of the area.

The final document is intended to complement the approved policies in the West Oxfordshire Local Plan.

It is also intended to help with planning applications.

There is a rolling programme of Character Appraisals.

Appendix 5 - Alterations and extensions The following advice should to be used as a guide to the type of design approach likely to receive favourable consideration when submitting applications for planning permission. Although orientated towards older, traditional house types, the advice applies equally to all types of domestic property, irrespective of age or size.

Most houses need altering or enlarging from time to time to meet the evolving needs of successive owners.

However, many existing buildings in the District have a scale and character worthy of retention.

The following pages are intended to acquaint applicants with design standards which the District Council will seek to attain in respect of alterations and additions to any type of dwelling.

The District Council recognises that most houses have the potential to provide the increase in space, standards and amenities required by modern living. What matters is the way in which this is done.

Apart from general planning and highway considerations, it is expected that in all cases the basic size of the existing property will be respected and that alterations and extensions will take into account the scale and character of the original house.

Buildings which are allowed to ďŹ ll their private garden area can provide sub-standard living conditions, and such extensions are unlikely to be permitted. Similarly, extensions which lead to a loss of daylight to neighbouring dwellings should be avoided. This point will always be taken into consideration when dealing with such applications.

West Oxfordshire Design Guide

A5-1

Applications for Planning Permission It is helpful if, in all cases relating to the alteration of an existing property, the drawings submitted to the Planning Department are in accordance with the Guidance Notes. The drawings should incorporate the following information:

Gaps and spaces Gaps between buildings and spaces around buildings are important: some should be retained, and others filled in.

• Plans and elevations of the existing property.

Where the proposal relates to a semi-detached or terraced dwelling the submitted plans should include elevations of the neighbouring properties; • Plans and all elevations of the property as proposed, together with sections where appropriate;

The effect of a building group can be severely damaged by poor extensions, or by extensions which are too large or are not in harmony with the adjoining properties.

• Full details of materials, both existing and proposed; • Location plan to 1:2500 or 1:1250 scale, taken from Ordnance Survey Sheet; • The appropriate statutory fee.

Garages

It is strongly advised that in all cases expert advice should be obtained before submitting an application.

These can be obtrusive in a rural setting, and if added to small cottages can destroy their scale and alter their character.

More detailed written guidance is available from the Planning Department.

It is better to disguise garages if possible, by turning them 90° and siting them away from the property, or by building car ports instead to lighten the effect.

A5-2

West Oxfordshire Design Guide

Character

Plan form and roof

The character of any house depends on a number of elements such as: • Size and shape of the plan; • Roof pitch; • Window openings; • Materials; • Surroundings and background.

Taking an existing plan form. . .

The SPAN is an important dimension.

Span

assymetrical and irregular; small square windows; rough rubble stone work.

symmetrical and composed; elegant vertical windows; smooth faced stone work.

If the house is extended under a pitched roof of similar span and pitch to the original, it is usually a visually successful addition.

Not like these...

Older properties often have interesting backs which add to and compliment the character.

Retain these if you can.

Consider where appropriate either carrying the roof down to enclose the extension:

These are poor extensions, the ‘completeness’ of the property has been lost, the elements of the original building have not been recognised in the extensions.

Or building a linked extension:

West Oxfordshire Design Guide

A5-3

Windows

Dormers

Older cottages usually have small windows with large amounts of wall round them. Too great an increase in the size of the openings can destroy the character. . .

Dormer windows should always be small and related to the scale of the building and pitch of the roof: Rather than be of signiďŹ cantly different proportions or pitch:

Especially if the new windows don’t match each other, the door openings are blocked up and the chimney stacks are removed.

Porches Porches, too, should relate to the scale and proportion of the original building; roof coverings should match those of the main roof if possible.

existing In other words, if the windows are like this:

Either match them exactly when adding on or, to increase the light in the rooms, add new windows.

Of the same size or in scale,

But not wider and deeper and with heavy lintels.

To really make them look right, set windows in stone walls a minimum of 100mm behind the outer face of the wall.

A5-4

Materials

Conversion of agricultural buildings

The materials used to build an extension are important. Try to match the colour, tone, size and texture of the original material, whether it is stone, brick or rendering.

Where planning permission has been given for the conversion of an agricultural building, detailed proposals which seem to extensively alter the basic character, or which amount to a re-building, will not be acceptable (see also Appendix 8).

The character of a barn is derived from its original use as a working agricultural building.

Try to retain the original form and alter it as little as possible externally. . .

When matching rooďŹ ng materials, always match the details of the original roof construction as well.

Existing building: Simple verges – no barge boards; Simple eaves – no overhang; Extension to match.

Rather than cluttering the building with additions and elaborate alterations.

Roof Avoid raising the roof, altering the pitch or installing windows in the roof. Dormers will almost always be inappropriate.

Walls Retain existing openings, particularly any arches or lintels. Avoid creating new windows or doors. Where openings need to be blocked up, use a contrasting material or inset from the wall by 25mm. In the case of large barn doors, dark glass or boarding may be appropriate. Minimise external pipework. Avoid modern materials (e.g. plastic front doors) or overly ornate details.

Large extensions will not normally be acceptable. Try to use the form of any other buildings in the group. This is especially important for the provision of garaging.

West Oxfordshire Design Guide

A5-5

Permitted development This is development strictly limited in extent, which does not require planning permission (although consent may be required under Building Regulations).

This is complicated matter. In cases of doubt please consult the Planning Department for advice, including for confirmation of whether or not planning permission is required for the development proposed.

Two settlements in West Oxfordshire - Great Tew and Taynton - are subject to the extra protection afforded by an Article 4 Direction, which entails the openended removal of specified permitted development rights. Article 4 Directions also cover a range of lesser sites and parcels of land in the District.

Full information to allow the assessment of the likely impact on the listed building and its setting must be provided.

Sources of guidance The general requirements for DASs are set out in paragraphs 56-110 of DCLG Circular 01/2006. This can be found at: http://www.communities.gov.uk/ pub/715/Circular0106DCLGGuidanceonChangestothe DevelopmentControlSystem_id1500715.pdf (The Circular recommends that applicants follow an assessment-involvement-evaluation-design process).

The CABE advice Design and Access Statements: How to write, read and use them can be found at: http:// www.cabe.org.uk/AssetLibrary/8073.pdf

Listed buildings Alterations to buildings listed as of Architectural or Historic Interest will probably require Listed Building Consent even if they fall within the terms of ‘Permitted Development’ for normal planning control.

Design and Access Statements Design and Access Statements must accompany all applications for Listed Building Consent and all planning applications in: Conservation Areas, Sites of Special Scientific Interest, The Cotswolds AONB and The Blenheim World Heritage Site.

Statements should not just describe the completed scheme, but show the ways in which the design has evolved. The Statement must demonstrate how people of all ages and mobility will be able to use the buildings and places that are proposed. The Statement must show how the buildings and spaces will be arranged on the site, what they will look like, and how they will relate to their surroundings. It should be written in plain English avoiding jargon, and be succinct and wellillustrated.

In addition, applicants for Listed Building Consent must be able to justify their proposals. They will need to show why works which would affect the character of the listed building are desirable or necessary (PPG15).

West Oxfordshire Design Guide

Appendix 6 - Repairs and alterations to traditional buildings Traditional but often unlisted buildings are vital components of the character of Conservation Areas.

Seemingly small but inappropriate alterations to these buildings can easily damage the appearance of the wider area.

Boundary treatments, such as stone walls or native hedging, which are characteristic of the area, should be retained. Coniferous hedging and timber panel fencing often appear incongruous and out of place in traditional settings.

The repair of traditional windows and doors is often a better and cheaper alternative to wholesale replacement. Draughty and ill-fitting windows and doors often only need stripping of old paint layers.

For reducing noise and draughts, secondary glazing and draught proofing are very effective alternatives to sealed unit double glazing. Traditional window designs are fundamental to the character of local buildings.

When replacement windows are installed these should match the original designs. Modern top hung night vents and large sheets of fixed glazing are rarely appropriate. Timber windows and doors are generally appropriate. Modern substitutes such as PVCu and aluminium do not look the same, and generally have poor environmental consequences. Modern Georgian style doors with integral fanlights have no historical basis and should be avoided.

Damp in traditional buildings

Paint is the traditional finish for external joinery.

European hardwoods such as oak and elm were usually left unfinished to weather naturally. Timber stains and varnishes are modern introductions, and need to be chosen with care to avoid inappropriate colours.

The repointing of stone walling and brickwork should always be undertaken with great care, as the visual character of a building or boundary wall can be destroyed by ill-advised work. Hard cement-rich mortars and raised ribbon pointing should be avoided.

Bagged mortar joints are the traditional finish in the District. Roughcast render on stone buildings is a traditional finish, and should be retained where existing. Removal of stucco or render finishes can expose poor quality porous stone to unacceptable weathering. External finishes of this kind were often an essential part of the original architectural concept, and they should be retained or restored wherever possible.

Traditional building techniques involve the use of materials that are porous and which allow moisture in solid wall construction to ‘breathe’ (i.e. to evaporate naturally from the external stonework or render). Local limestone laid in lime mortar, with lime plaster internally and perhaps lime render and limewash externally, allows the structure to breathe and is flexible enough to accommodate structural movement.

However, many traditional buildings have been unwisely repaired or ‘improved’ using hard and impermeable modern materials which trap moisture, making natural evaporation impossible. The results are often severe dampness and condensation. Where proprietary ‘damp proofing’ installers are called in, the problem is frequently misdiagnosed. This occurs because of the use of electrical resistance meters designed for timber rather than masonry. Surface meter readings on walls can be misleading as salts deposited on an inner surface will carry electric current even if the wall itself is relatively dry. Invariably recommendations are for even more impermeable materials, which at best may mask the problem. The most accurate test of moisture content in masonry is the laboratory oven-balance method described in the Building Research Laboratory Digest 245.

Stone or brick walling should not be painted as this can lead to damage of the walling materials, as well as resulting in dramatic visual alteration.

West Oxfordshire Design Guide

A6-1

Chemical damp course injections, tanking and even dry lining are common prescriptions wherever the basic characteristics of a traditional building are misunderstood.

In the worst case, sealing the external and internal surfaces leads to a dramatic rise in the moisture levels within in the structure.The removal of internal plaster to a height of 1-1.5m and the application of a waterproofing plaster system masks the effects of injection systems. In thick irregularly filled stone walls it is generally impossible to form a completely waterproof layer.Where the layer is incomplete, moisture will be forced up under increased pressure. In time this can lead to a ‘tide mark’ as the moisture is driven ever higher, causing structural damage to any timber fixings, joists or window seats.

Simple ways to avoid dampness in traditional buildings:

A

• Ventilate and heat the building properly. Ensure that the roof is in good condition. Check that gutters and downpipes do not leak. Many problems are caused not by ‘rising’ but ‘descending’ damp.

• Ensure that downpipes discharge to drains or soakaways some distance from the building. If they empty direct to the ground, the water will track back into the building. (A) • Ensure that the external ground levels are as low as possible and well drained. Consider the use of a ‘French drain’. http://www.ihbc.org.uk/ Technical%20Papers/French%20Drains.htm

B

• Prevent the saturation of external walls by flush pointing using a lime based mix. This will also promote the evaporation of any moisture within the wall. Cement-rich mortar should not be used as this will trap moisture and may lead to frost damage. (B) • Where modern gypsum plasters have failed in damp conditions they can be replaced with lime plaster which will reduce condensation problems. Pozzolan additives for lime plasters help them set in damp conditions. Hard cement renders can be replaced with lime renders. Lime renders should not be sealed with an impervious paint. Limewashes would be used to resist penetrating rain and can be mixed with oils, tallow or other ingredients to reduce water penetration. Silicate masonry paints may also be suitable. (C)

Appendix 7 - Traditional details Modern buildings with traditional details The traditional stone buildings of West Oxfordshire can be used as a source of design ideas for new buildings. Traditional character is defined by a number of features, including the size and shape of the plan, the roof pitch, the window openings and the materials. Illustrated on this page are some new houses that have been designed with modern materials, but which have a well defined local character.

This house has a simple rectangular plan with a narrow gable.

The walls are of artificial stone in a colour and texture to match the local limestone. It is laid in courses of different heights, and the mortar colour matches the masonry.

The roof is covered with artificial blue slates, and the gable has a flush red brick chimney. The recessed door and window openings form a simple regular pattern. The double glazed windows are balanced and symmetrical in each opening. They have a single horizontal glazing bar.

David Wilson Homes

Simple individual house types can be combined to form terraces and groups.Variety can be achieved by, for example, expressing differences in natural levels, and any variation in the width of individual houses will result in differences in ridge height. In this example a lowered eaves line and half dormers together add interest to the terrace.

A.Corfield, Architect

Recently completed new houses in a traditional village setting.

These feature artificial stone slates, vertical sliding and side hung casement windows, as well as decorative porches.

Front garden areas are defined by traditional dry stone walls; elsewhere the buildings themselves mark the edge of the road or pavement. In this example parking is provided to the rear of the houses.

Appendix 8 - Conversion of agricultural buildings Traditional agricultural buildings contribute to the beauty of the West Oxfordshire landscape. The best possible use for these building is the one for which they were originally designed. However, when they become redundant, appropriate new uses should be found to secure their conservation and active use.

This may or may not involve conversion or change of use. Where the Council does permit conversion the primary purpose is to secure the retention of the building and its contribution to the character of the surrounding area. Whilst Policies generally encourage the re-use of existing buildings, the conversion to residential use generally involves such dramatic alterations that the original character of the building is damaged.

A

The process of conversion should begin with a thorough understanding of the architectural character of the building. The varying functions of agricultural buildings led to different shapes, sizes and details, all of which must be recognised and protected in any conversion.

Barns were built for the storage and processing of grain. They are generally rectangular in plan with central cart openings on each side. Walls do not generally have other openings (except perhaps for ventilation slots). Roofs are solid. (See A)

B

Granaries were built for the storage of bagged and processed grain, are smaller than barns and are set upon vermin proof bases (staddle stones) above ground level. (See B) Cartsheds and stables have openings that directly correspond with their original functions. Sometimes these activities took place in different parts of the same building resulting in a more complex form. (See C)

Conversion principles



Walls: • Existing openings should be retained; • Where openings need to be blocked up, a contrasting material should be used, or the infill inset from the wall by 25mm; • The creation of new windows and doors should be avoided; • External pipework should be minimised.

Roofs: • Unbroken roof slopes should be retained; • No alterations should be made to the pitch of the roof; • The insertion of windows (both rooflights and dormers) should be avoided; • Where rooflights are used, they should be flushfitted with internal gutters and non-reflective glass, and should not be on outward-facing pitched roofs; • The form or ‘silhouette’ of the building should remain substantially unaltered; • Chimneys are residential features, and should be avoided.

Materials: • Existing materials should be retained and re-used; • Artificial slates and tiles, reconstituted stone, concrete, aluminium and plastic should not be used; • Original features and details, such as buttresses, lintels, owl windows and datestones should all be retained.

A8-2

West Oxfordshire Design Guide



Interiors: • The open nature of most barn interiors, together with any visible roof structures, should be retained; • Internal divisions should be limited, and the cutting of internal frames and joints avoided.

Curtilages: • The open nature of farmyard or courtyard groupings should always be respected; • The relationship between the building and the surrounding landscape should be retained; • Residential features – such as car parks, lighting, gardens, sheds, patios, washing lines etc. – will have a detrimental affect on the agricultural character of the building’s setting and ideally should be avoided, or their impact minimised; • Boundary features can reinforce rural character, and can take the form of stone walling or timber post and rail fencing.

Residential conversions: • Residential conversions are generally the most difficult to undertake successfully because of the need to provide upper floors, doors and windows that were not features of the original design; • Further problems include the loss of elevation unity and building integrity when farm buildings are subdivided; • There is a general presumption against residential conversions in small villages and in the open countryside.

West Oxfordshire Design Guide

A8-3

Commercial uses: • Commercial uses are often more appropriate than residential uses, as small workshops, offices or studios (i.e. B1 uses) can be created with minimal interventions to the building or its surroundings; • However, issues relating to parking, noise, fumes and traffic will first have to be carefully addressed.

Recreation and tourism • Recreation and tourism can also represent appropriate uses for traditional farm buildings. The open and expansive interiors of barns give them the potential for community uses such as halls, meeting rooms and community centres (again, this can be achieved with only minor amendments to structure and setting); • Some traditional farm buildings can be developed as attractions in their own right (incorporating, for example, farm shops, cafés, workshops, exhibitions on farming life etc); • Some farm buildings may also have the potential to provide overnight accommodation (as e.g. holiday lets or camping barns).

9 - Street scene and the public realm The finest streetscapes and public realms generally have the minimum amount of street furniture and surface markings. That which is essential is sited to reinforce an underlying sense of visual order. Improvements to streetscapes and the public realm should enhance local distinctiveness and reinforce those qualities which make an area special. The most modest schemes are usually the most successful in reinforcing a sense of place and making streets attractive for people. In order to achieve high quality streetscapes and public realms: •

Use a townscape analysis to identify the visual, spatial and historic qualities that make an area special;

•

Observe and respect local detail in surfaces and street furniture;

•

Limit formal design to formal spaces. Informal or vernacular spaces should follow their functional tradition;

•

Provide for regular management and maintenance.

Street management No single authority or agency has control over – or responsibility for – the presentation and management of the street. The impact of roads and traffic on the historic environment can be minimised if works are coordinated.

Street audits, carried out jointly by highways and urban design/ conservation staff, will identify surviving historical materials and details. Investing in quality will provide enduring value for money. If resources are limited, doing less of a high standard is better than compromising by doing more of a lesser quality. However, all investment must be protected with adequate provision for maintenance.

Ground surfaces Paving forms the foreground of almost every street scene. Quality in the design and construction of footways and street surfaces is vital to the character of an area. It provides the context within which the buildings are seen.

• Relate ground surfaces to the local context; • Keep paving simple and avoid discordant colours; • Maintain and restore historic paving and detail such as kerbs.

The paving slabs are laid using a traditional bonded pattern found historically throughout the District (as here in Witney).

Stone kerbs are flush with adjacent road surfaces which feature stone setts. Concrete block paviours had bonded yellow lines applied before laying.

Other traditional surfaces: Pebbles embedded in lime mortar base; and pitched limestone paving.

New surface treatments: footway and flush road surfaces using coursed and bonded concrete paviours and aggregate embedded bituminous road; paving bordered by wood chip and planting.

Traffic management Traffic calming measures should be fitted with sensitivity into the street-scene, as though they were part of the original design of the area. Adopt a minimalist approach. Physical measures should involve minimal visual interference with the established streetscene.

A9-4

West Oxfordshire Design Guide

Street scene and the public realm The streets and roads of West Oxfordshire are increasingly cluttered with a proliferation of traffic signs, bins, bollards, guard rails and street furniture.

This results in streetscapes that are both unsightly and lack character. Coordinated action is needed to reverse this decline.

Retaining historic features keeps the streets’ individuality and helps create a sense of place. It can contribute to regeneration: well-designed, well-ordered and well-maintained streets are an expression of a confident and caring community.

Rural environment dominated by intrusive signage which is too high and projects over hedgeline; unnecessary multiple footway. Footway appearance dominated by rumble strips and painted surfaces.

West Oxfordshire Design Guide

A9-5

Street furniture Retain historic street furniture which reinforces local character, but identify and remove superuous or redundant items.

Minimise signage, and locate signs on existing lamp posts or buildings, or at the back edge of the pavement; use a single dark colour for all items.

Reduce guard rails to a minimum and use designs that relate to the townscape, such as traditional post and rail fencing.

Avoid standardised lighting and choose the design and light source most appropriate for the area.

Wherever possible, eliminate the need for bollards through good design; where unavoidable use designs and materials appropriate to function and context.

A9-6

West Oxfordshire Design Guide

Boundary treatments Boundary treatments should be carefully chosen to reinforce local character. Metal railings were a common feature during the 19th century and can be appropriate to modern urban settings.

Traditional parkland fencing is well-suited to the edge of farm- or open land.

Traditional walling types can be adapted to modern urban settings. Note parkland-style tree guard.

Other types of boundary feature, including hedging, willow hurdles and slatted fencing, are especially well suited to the rural context.

West Oxfordshire Design Guide

Appendix 10 - Stonework In West Oxfordshire, the grey or buff-coloured oolitic limestone is the predominant walling material. This material was traditionally laid dry for field boundaries, or with lime mortar or loam for buildings. The stones were fitted together as closely as possible, so that very little mortar showed.

Walls were laid to give a face on both sides, the irregular ‘tails’ of the stones pointing into the middle.

Any voids remaining would be packed tightly with bonded stone fragments. This method of laying gives a much greater thickness than a modern wall.

Limestone is a sedimentary rock formed from seabed deposits in the Jurassic period. The stone should be laid with the sedimentary layers parallel to the ground.

If laid the other way, with its sedimentary layers parallel with the wall face, frost action will peel off the surface, and progressively weaken the wall.

Before laying, the stones should be sorted into piles of random lengths but the same course height: 3” (75mm) or 5” (175mm) are typical course heights. The larger stones were generally reserved for the base or corners (for use as quoins), and door or window edges (for use as jambs). The stones were generally laid level in regular courses, or, if the stones are very irregular, ‘brought to course’. Two or more thin courses would often be masked by a larger quoin or jamb stone. A skilful blending of different course heights creates a pleasing and harmonious visual pattern.

The mortar between the courses - the ‘bed’ - or between stones in the same course - the ‘perp’ or ‘perpend’ - should be as thin as possible. On average it should not be thicker than half an inch (10-12mm) in depth. Any projections on the stones which may enlarge the joint should be trimmed with a walling hammer or bolster (chisel). Stones should be selected to be compatible in shape with their neighbours.

Courses should be laid level on top. Any variation in shape will then be taken up in the top of the bed joint below.

The mortar must be slightly set before it is finished.

This can be done with a trowel, brush or corner of a butterfly walltie. Care should be taken to avoid smearing mortar on the stone faces. The joint should be finished with a flush or concave surface, slightly

recessed from the arris (corner) of the stones above and below. Projecting or ribbon pointing should not be used, since this will trap moisture in the wall.

The wall should have a unified and integrated appearance, with neither the individual stones nor the mortar pattern drawing attention to itself.

Mortar The preparation and use of mortar is of particular importance. The mortar colour and texture must relate to the chosen stone. Dense, cement rich mortars are not appropriate for limestone. When dry, the mortar should be of the same colour, but slightly lighter than the stone.

The ingredients for mortar are: Aggregate - crushed stone or coarse sand with a full range of particle sizes up to a maximum of 1mm. Fine, soft or loamy builder’s sands are not suitable. However, ‘concreting’ sand may be appropriate.

Lime - Lime putty is preferable, but if powdered lime is used this should be mixed with water to a creamy consistency and left overnight to mature.

Cement - Ordinary Portland cement or white masonry cement.

Recommended mortar mix: 1 part cement to 3 parts lime to 12 parts aggregate. Proportions to be by volume not weight. Accuracy in mixing is vital to avoid variations in colour.

For new buildings it is likely that only the outer skin of external walls will be constructed of stone.

Newly quarried stone is available which will allow the construction of stone skins of between 100150mm. The stone selected should be appropriate in relation to its colour, texture and range of available sizes. This should generally match the adjacent stone of the locality. See Appendix 9 for a list of local quarries.

A10-1

Artificial stone

Sample panels

The purpose of using artificial stone is to replicate the character and appearance of local natural stone. It is essential, therefore, to create as natural an appearance as possible using the artificial material.

To demonstrate the natural or artificial stone type, laying pattern, mortar colour and finish for a given building project, a sample panel using the material should be constructed, approximately 1.000m by 1.000m in size. The sample panel must be separate from the development, but in a position on the site where it can remain until practical completion, as it will serve as the standard against which all other stonework will be assessed.

Artificial stone is available in 100mm thicknesses, to allow the formation of an outer skin. Ideally, artificial stone should be available in a large range of course heights and stone lengths. If only a small range of sizes is available, the finished wall will have a repetitive and mechanical appearance. Artificial stone should be laid with stones of varying lengths in the same course height. The courses themselves should vary in a harmonious random pattern. The use of square stones (or ‘jumpers’) as random features should be avoided.

Larger stones can be used at corners and to define window or door openings.

The stones should be laid with a 10mm average bed joint and a 10mm average vertical joint ‘perp’. This practice follows the advice for natural stone. The joint profile should be slightly recessed, matching that of natural stone. The mortar should be similar in colour to, or slightly lighter than, the artificial stone. Difficulties frequently arise when using grey Portland cement or very dark sand. A pale buff to neutral colour is generally appropriate for artificial stone, but the exact shade will depend on the choice of artificial stone.

On some sites in West Oxfordshire, Euromix CPI mortar (reference M3WLY24) has been found to be appropriate for use with lighter artificial stone.

Possible artificial stone types Forticrete - Standard Split Face, Bathstone.

Bradstone - Weathered Cotswold or Southwold shades.

Rebastone - Split and Rustic walling, Oolite or Cotswold.

A10-2

When complete, the sample panel should be protected from frost and rain, and the mortar allowed to dry out before an inspection is requested. Until the sample panel has been approved in writing, no external stonework should be carried out, even below the damp proof course.

Appendix 15 - Paint and stain finishes on external timber Traditional finishes

Paint colours for traditional contexts

In West Oxfordshire, traditional finishes for external timber fall into three general categories: 1. Paint Finishes - on softwood and hardwood doors, windows and door frames from the 18th century and later.

2. Pitch and Tar Finishes - weatherproofing with a dull black appearance, mainly on frames and boarded surfaces of agricultural buildings.

3. Natural ‘bleached’ surfaces - Weathered patina of grey or silver on oak, elm and chestnut.

Compatible modern finishes Where finishes for modern work are required to match existing work in, for example, Conservation Areas; or where alterations to existing traditional buildings are to take place the following approaches are recommended: Paintwork - white/ off-white or other pale colour.

‘Burford Green’ (BS 12 B 17 or similar). There are specific guidelines for Great Tew and informal guidelines for Burford. For front doors and shopfronts, dark primary colours are recommended.

Dark Finishes - (to match the ‘pitch/ tar’ tradition), ‘Ebony’ stains such as those by Dulux, Jotun or Sigma.

Light Finishes - (to match ‘bleached’ timber tradition), ‘Light Grey’ (Ref. 625 by Jotun), or a light wash of black external stain diluted with white spirit, to give a pale grey colour.

The above recommendations are not exhaustive and suitable alternatives exist. However, there is NO traditional precedent for the use of modern red/ brown stains widely available in DIY superstores.

Their appearance is quite unlike anything known in the traditional palette. These materials are not suitable for use on traditional buildings or in Conservation Areas unless part of an approved design approach.

Appendix 16 - Art for public places Recently, West Oxfordshire District Council consolidated its approach to developing Public Art, by introducing a new policy (TLC7) in the adopted West Oxfordshire Local Plan 2011.

Public Art is usually created by visual artists and craftspeople for a specific site, working in collaboration with other professionals such as architects, landscape designers, planners, developers and arts officers. The artists, where appropriate, should work in consultation with the people who will be affected by the site and the installation.

Public Art is intended to be freely and physically accessible to the public. It may be owned by the community, though it can be located in private places and serve a community of interest. It can be permanent or temporary.

Commissioning public art Artists can positively influence building design, paving and landscaping features and explore issues of place, identity and community.

Commissioned art work can include: • Earthworks and landscaping, both hard and soft (e.g. paving, bridges, feature planting); • Street furniture – for example, seating or play areas; • Specialist treatment of some aspects of a building: mosaics, tapestries, murals, lighting, timberwork, etc; • Decorative stone carving; • Metal and glasswork; • Provision of space for artistic use; • Sculpture.

How does the public art policy work?

In line with adopted Local Plan Policy, the Council will normally seek a one percent contribution (or agreed cost equivalent) from the total development value of a proposal for an agreed art provision (as based on the ‘percent for art’ concept).

The Policy applies to public and private sector developments, (usually those which are large scale and include publicly accessible buildings and spaces).

Early consultation with the Council is recommended prior to an application being submitted.

In particular, this policy shall apply to the following forms of development: i. residential; • new builds of ten units or more; • significant conversions or refurbishment of existing buildings; ii. significant retail, commercial or leisure proposals, where the gross floor area is 1000m2 or more; iii. significant development proposals by utility operators and local authorities.

West Oxfordshire Design Guide

A16-1

What can the money be spent on?

• Commissioning of artists or craftspeople to participate in the overall design of the development or features within the development; • Commissioning of art works; • Purchase of materials or existing artworks for public display; • Consultation with the local community and relevant organisations; • School and Community Education programmes; • Dedication of space for the public exhibition of works of art; • Transportation, installation and maintenance of the art work.

How does public art benefit the community?

• It enhances the built environment; • It adds an individual and distinct character to the development; • Quality surroundings contribute to local identity and community pride; • Involvement of artists and the community can calm fears of environmental disturbance and help to convey the best intentions of the developer; • It creates work for local artists, safeguarding skills; • It assists in attracting investment to the area and stimulates the local economy; • It continues the long tradition in Britain of high quality design features; • Permanent public art is long lasting and forms part of our heritage.

Appendix 17 - Bin storage and recycling Bin provision The introduction of ‘wheelie–bins’ and recycling boxes has led to problems with the storage of these containers. Often, they are left on footways and public areas because convenient and accessible storage is not available within the property.

Consideration must be given not only to the provision of bin stores, but also to whether or not householders are likely to feel adequately encouraged to make consistent use of these areas.

Bin storage Flexible bin storage areas must be included in the design of all new and converted buildings.

For new houses, ventilated provision must be made within the building enclosure, garden or yard. A ventilated built or fenced enclosure must be provided for communal bin storage in the case of flats or multiple occupation residential properties and all new commercial or institutional properties. These must be easily accessible from the property they serve, and allow the easy return of the bins after emptying.

Collection points must be no further than 20 metres from the Refuse Vehicle access point.

The design of bin stores must take into account the likely future increase in the number of bins per household, as there is further separation of waste materials.

West Oxfordshire Design Guide

A17-1

Household waste: West Oxfordshire households are generally provided with one 140 litre bin and two 55 litre recycling boxes.

A 140 litre wheelie bin is 480mm wide, 555mm deep and 1070 mm high. The maximum load is 70kg.

Enclosures must allow easy access for users to ďŹ ll the bins and for collection crews to remove them.

They should have level non-slip surfaces for wheeling out the bin for emptying. The enclosures should be well ventilated and easy to wash out. The enclosure walls and surfaces should be designed to complement the surroundings.

Kerbside collection: The size, weight and turning dimensions of refuse collection vehicles may vary over time because of operational considerations.

Access roads to bin stores must meet the minimum width requirements as set out in the current Oxfordshire Highway Design Guide; there must be adequate turning areas for collection vehicles, and any surface likely to be crossed by refuse vehicles must be able to take that vehicle’s weight.

Communal bins: Communal bins have capacities of 660 litres and 1100 litres (the preference being for the larger size, again to help collection speed). The number and size of bins should be based on 140 litres of general waste per household. If access on to the development by the appropriate refuse collection vehicle is not possible then large communal bins may not prove feasible.

Recycling: As a general rule in West Oxfordshire, each household is provided with two 55 litre recycling boxes: one for glass and one for paper, cardboard, plastic and tin. Where a development contains flats it is not practical to provide boxes, but rather communal bins within a central store (one 360 litre bin for up to ten flats for glass and one for every three flats for paper/cardboard/plastic and tins, should be provided).

Access to the recycling storage would be the same as that outlined under the storage guidance for refuse containers. More comprehensive provision for recycling can be found at one of the District’s waste and recycling centres.
