Design and Access Statement

Lakeside House

1.0 Introduction This application is for the creation of a single family dwelling of similar footprint to a previously approved scheme.

The application site, Lakeside House is located about 1km to the South East of the village of Penshurst. It extends to approximately 6.6 Acres (2.66 Ha) and is accessed from a shared private drive from Poundsbridge Lane.

Grade II listed Swaylands House stands on high ground to the north of the application site, with panoramic views to the Medway valley beyond. The application site lies on lower ground approximately 250m to the south of Swaylands House. Although lower than Swaylands House, the land is still elevated with good views to the south and west over the Medway Valley.

The site is within the High Weald AONB and lies within the grounds of Grade II registered park and garden of Swaylands (list entry 1001280). The gardens were developed in the later part of the 19th century and early 20th century. Of historical interest is the rock garden which is of monumental and extraordinary scale. It includes steps connecting the main house and gardens to the boating lake, evidence of cascades, the supply of water to the lake, and pockets for planting - some of the original planting survives. On the south side of the boating lake is a boat house. To the west of the lake is a ha-ha wall which looks over a parkland landscape to the south west.

Above: Aerial view with the development site highlighted in red.

We are driven by the importance of building a home that respects its context in the High Weald AONB and the site itself, protecting its neighbours amenity and reflecting the highest standards in contemporary architecture.

The rock garden created by George Drummond, is one of the largest rock gardens created in the early 20th century and whilst overgrown the structure of the garden remains generally in good condition. It was created at a time when large scale rock and water gardens were fashionable. The rock garden, including the part in separate ownership of Swaylands House, was built from sandstone blocks cleared from a local quarry. The design for the garden was on a grand scale with towering walls, paths, steps, ravines and grottoes. The Grade II designation of the garden confirms its special interest as a designed landscape, and that it warrants preservation. Its special significance is afforded by its unusual scale, monumentality, quality of design and construction, and the degree of survival, albeit now in fragmented ownership.

k Trac

At the beginning of the 20th Century the lower pond of Swaylands was increased in size and a large rock garden was built around the pond. The water was of sufficient scale for a boat house to be added which is still visible on the site today and is proposed to be refurbished as part of the proposed works.

Access to the site The site is accessed via a relatively steep shared private drive off Poundsbridge Lane.

At the junction of the private drive with Poundsbridge Lane, the Grade II listed, roughly-dressed, sandstone boundary wall of Swaylands ends and the wall becomes lower and more random in nature like the rockery on the site allowing for flowering plant to nestle and flourish.

The pond has now been completely covered by bulrushes to the extent that no water is visible in summer. The application is accompanied by a Management and Maintenance Plan prepared by Askew Nelson. This suggests that due to the pond having a liner the bulrushes can be removed from the pond by hand, retaining small groups on the edge of the pond.

2.3 The history of the site Below is provided a general history of the site. More detailed information is contained within the Landscape Heritage Statement prepared by Askew Nelson that accompanies this application.

A Brief History of Swaylands William Woodgate, a local solicitor and member of a prominent local family, bought a farm and 33 acres of land from Penshurst Parish in 1835/36. The original Swaylands house, a villa shown to the right, was built from around 1837 for William Woodgate.

Guttering boxes on the original villa marked “1842”, suggest the likely date of completion. By 1859 Woodgate had sold Swaylands to Edward Cropper.

Cropper employed the architect George Devey to extend the house greatly and to terrace the gardens.

Edward Cropper died in 1877 and the estate was bought by George Drummond.

Between 1879 and 1882 Drummond made further additions to the house and in the 1890s he commissioned the Arts and Crafts architect, Sir M E Macartney to build a large pilastered conservatory at the north western end of the house.

When George Drummond bought the house it was described as ‘rather modest...he [George Drummond] spent the next seven years building wings, then tearing them down; creating an enormous place with its own theatre, ballroom, picture gallery, orangery and even an indoor cricket pitch.

George Drummond busied himself, during 21 years with his Head Gardener Christopher Hosier and Robert Hosier laying out what was supposed to be the biggest rock garden in the world - an expanse of 40 acres with lakes, waterfalls and huge chunks of sandstone brought from a quarry 5 miles away on farm wagons.

When he had first mentioned the idea of the rock garden to Sir Henry Streatfield, the owner of the quarry, he was told he might help himself. By the time the rock garden was finished the quarry was empty (The Drummonds of Charing Cross, Bolitho & Peel, 1967). The English Heritage Parks and Garden citation states that George Drummond eventually bought the quarry. The rock garden is first shown on the 2nd edition Ordnance Survey map 1897 shown below as a rocky outcrop in the top right of the map segment below. The lower pond is shown smaller than it is now, in a kidney shape. By 1907 when the 3rd edition Ordnance Survey map was published, the rock garden is shown in its complete extent. The rock garden was extended to the north, south, east and west, an additional pond created to the south with the rockery connecting upper and lower ponds. A boat house was constructed on the lower pond. The rock work is on a grand scale with paths, steps, ravines, grottoes, an arch, and a top-lit cavern leading through it, and was once planted with choice alpines.

Above: 2nd. Edition Ordnance Survey Map, 25” to mile, rev. 1895 publ. 1897. Note the rock garden at this stage appearing more as an outcrop of rock. There are no paths laid out around the rock garden and the lower pond is probably not yet within the garden. Approximate outline of the application site shown in red.

Remaining Chronology 1919

George Drummond sold Swaylands to Sir Ernest Cassel who converted the house to the Cassel Hospital, a hospital for nervous disorders.

1927

The stable block was converted into accommodation for nurses in 1927.

c.1939

At the advent of the Second World War, the government gave notice that Swaylands was to be requisitioned as a military hospital.

WWII

The rector of Bidborough mentions bombs falling in the rockery. Some of the shattered sandstone was taken away to repair the church tower in Bidborough.

1946

Middlesex County Council bought the estate in poor condition.

1949

Swaylands opened as a “Special Needs Residential School for Boys”.

1994

The school closed due to financial constraints.

1995

Gama International bought Swaylands in 1995. Continued deterioration of the house and grounds occurred during this period.

c2000

Swaylands was purchased by a series of property developers, and then by Heritable Capital Partners Limited with a view to redevelopment as apartments.

Towards the end of the restoration of the main house and gardens, Heritable Capital Partners Limited entered into administration (15th October 2008). Ernst & Young were appointed as administrators, and the restoration of the original house, construction of two additional new residential blocks and restoration of the gardens and grounds continued to completion.

Heritable Capital Partners Limited gained permission for the Swaylands site to be subdivided into two sites.

1. The main Swaylands site containing the Grade II listed Swaylands House and the other houses and residential buildings 2. The site to the south that was created is the site to which this application applies. Permission was granted in 2002 for the erection of a single dwelling house.

2.4 The setting today The site has not been adequately managed for many years; The rockery area in particular is overgrown. The ponds water is no longer visible as the whole area is covered with Bulrushes and is heavily silted.

The site has been in limbo for over a decade since the conversion and extension of Swaylands House, to residential apartments. The site forms part of the Swaylands Estate and benefits from planning permission for the erection of one dwelling house.

Planning permission SE/02/01110/FUL was proved extant through the Granting of a Certificate of Lawful Development, reference SE/12/02985/LDCPR.

2. Woodgate Manor apartments is over 150m from the proposed dwelling and therefore, we believe that there will be no impact on privacy.

3. There are various outbuildings to the south that will benefit from screen planting to the boundary, incorporated into the landscape design.

4. Swaylands School Farm is located to the south. It is nearly 50m from the proposed dwelling and therefore we believe that there will be no impact on privacy.

Following a meeting to present our proposed design, Swaylands Estate management kindly allowed us to walk around the grounds to understand the relationship between our proposed design, the parkland landscape and apartment buildings.

The adjacent photographs and those on the following sheets show how, from the residential apartments of Woodgate Manor and the main Swaylands House, our proposed design has little impact on the historic view over the boat pond, Swayland School farm and the wider landscape.

Residents of Swaylands take benefit from the extensive grounds and wonderfully maintained rockery. Some people do walk along the Swaylands side of the rockery at the boundary with the proposed site. Photograph 3 shows that privacy for the residents of the new dwelling needs to be considered and are addressed in the proposed landscape design.

Ga r

• It will be very difficult to see the dwelling from Woodgate manor due to the mature trees next to the apartments and at the rockery boundary.

Brick Cottages

• The proposed Corten Steel roofing of the dwelling means that the building will melt into the background rather than impose itself on the site like the approved scheme.

We believe that the right balance has to be achieved between retaining a visual connection between Swaylands, the lower pond, boat house and Swaylands School Farm and ensuring privacy for the residents of the proposed dwelling. The whole historic estate can not be re-united under one ownership, it has been split into three parcels and permission exists for a three storey house on the development site. ve

Swaylands Estate management kindly shared the above photograph taken in the early 2000’s when the site was previously cleared and the pond was clear of bulrushes. From this vantage point it would appear in this area, none of the original planting structure or paths remain. The proposed landscape design will however take historic evidence to re-instate the rockery garden and historic routes.

The upper pond rockery which is within the grounds of Swaylands Estate has been cared for and with the permission of Swaylands estate can also act as a reference in relation to the variety of alpine plants that can be re-introduced to the renovated rock gardens on the Lakeside house development site.

The above photograph, taken from a vantage point close to Westgate Manor, shows that the proposed dwelling will not be seen from the majority of apartments.

The creation of the legacy views mean that residents of Swaylands will still enjoy the historic vista from the top of the rockery. This does mean that in these areas the privacy of the Lakeside house site is compromised. We wish to balance this with privacy screen planting around retained trees T6 to T8 that is shown on this page. Further details can be found in the landscape document which accompanies the planning application.

Lakeside House Although the location of the proposed dwelling is on land higher than Swaylands School Farm, due to mature planting to the boundary that can be seen in the photograph below and the distance of the proposed dwelling to the neighbouring property (which is the same as the approved scheme) we do not feel that the proposed design will adversely impact the neighbouring property.

The proposed design will be more sympathetic to neighbours than the approved scheme due to the reduction in ridge height and unlike the approved scheme it will not principally face Swaylands School Farm or Swaylands.

2.6 Strategic Views The site itself is large with a lot of visual impact and interest.

1. On entering the site (once the Bulrushes are removed) there will be the most wonderful view across the pond with the boat house in the foreground and a layering of the vista. On coming to the site something else is spotted or focused upon every time, whether it be the mature trees, rockery, proposed building or the view down to the Medway river.

4 3 5

2. On approaching the dwelling we want to retain a level of permeability through the building to the rockery and mature trees at the boundary.

3. The mature Oak trees at the edge of the pond are located at the end of the rockery and provide screening of the house so that the dwelling will be slowly revealed rather than dominating the site.

2

4. There is an interesting view over the pond from the elevated position of the upper rockery with paths down to the lower rockery.

5. The site benefits from amazing views over the Medway valley.

Indicates outward looking views

Above: Site plan with strategic views highlighted.

The orientation of the site and the location of the neighbouring buildings mean that none of the strategic views we have selected for our proposed design look in the direction of the neighbouring properties.

Design and Access Statement

Lakeside House

3.0 Planning Policy The Framework sees achieving good design as a critical output of the planning process. The approved dwelling is not, in hindsight a sensitively designed and well-mannered building that integrates elegantly into the surroundings. Instead, it is a plain dwelling at odds with the historic parkland and rockery that materially damages its setting. This proposal represents an opportunity to achieve exemplar architecture that accords with the Framework.

The Framework also requires that the desirability of sustaining and enhancing the significance of the heritage asset and putting them to viable uses consistent with their conservation should be accounted for in planning decisions. The site is a significant heritage asset in its own right. The financial burden of maintaining the site, and enhancing it will be substantial over time.

Considerable financial means are required to protect the rockery into the future. A house of this type would bring the rockery into clear ownership and with precise controls on maintenance and repair.

That said, while the proposal does satisfy the objectives of good design and maintaining the heritage asset, there is a balance to be struck with Green Belt policy. Paragraph 145 of the Framework states local planning authorities should regard the construction of new buildings in Green Belt as inappropriate development. Paragraph 146 outlines further exceptions where they do not conflict with the purposes of including land within it from the definition of inappropriate development. This proposal does not fall within the exemptions and therefore is inappropriate development. Paragraph 143 applies.

Above: Approved site plan under approved scheme reference SE/02/01110/FUL

Planning permission already exists for a large three storey house on the site.

20007-DAS.pdf

Mr Robert Porritt

Design and Access Statement

Lakeside House

Paragraph 143 states “Inappropriate development is, by definition, harmful to the Green Belt and should not be approved except in very special circumstances”. Very Special Circumstances (VSC) that outweigh the identified (albeit modest) harm to the openness of the Green Belt are required. ADMP policy GB2 in respect of basements also applies. Criterions a) to e). deal with matters such as not exceeding the built footprint, for the basement to be situated entirely underground and for there to be no openings. The effect is that exposed elements of a basement need to comply with criterion e) of Policy GB1, which defines the exposed extent of the basement as inappropriate development. The volumetric impact of the proposal, including the basement results in 6.050m3. The existing approved dwelling extends to 4,150m3.

The starting point for considering whether VSC exist that outweigh the harm to the Green Belt is the established fallback position. The grant of certificate SE/12/02985/ LDCPR secures the fallback position for a dwelling on this Site. This confirms 4,150m3 of impact on the openness of the Green Belt. Planning permission for an iteration of the fallback position is at an advanced stage with work on the S106 agreement nearing completion under reference 19/00239/FUL. One way or the other, a house will be built on this site. This fallback position is afforded significant weight.

Above: Volumetric study of approved scheme under SE/12/02985/LDCPR

The contentious part of this development is the need to accept that the basement, while technically breaching policy and in volumetric terms adding circa 2,000m3 of built mass, is mostly buried. A volumetric comparison does not weigh the benefits derived from the exemplary architectural approach with the impact of the Green Belt and the heritage asset appropriately.

Above: Volumetric study of proposed scheme

May 2021

20007-DAS.pdf

31

Mr Robert Porritt

Design and Access Statement

Lakeside House

In Green Belt terms, the concept of openness encompasses both the visual and spatial aspects of the development. For land to be ‘open’ in these terms, it essentially means that it is free from development. Through the introduction of a partially raised basement and because the entire above-ground structure is inappropriate development, the proposal will result in definitional harm. However, the following factors constitute VSC that outweigh any definitional harm to the openness of the Green Belt:

The five VSC outweigh the definitional harm to the openness of the Green Belt. That assessment requires a nuanced judgement on the basement volume because mostly, it cannot be seen. Having regard to the limited visibility of the basement and the factors considered VSC in favour, a simple volumetric comparison alone does not support an argument that openness would be harmed. Weighing up the need for good design, preservation of the heritage asset and a solution less impactful than the fallback position, the case is made that VSC exist to justify the grant of planning permission.

1. The grant of certificate SE/12/02985/LDCPR secures the fallback position for a dwelling on this site. The value of the site means a house will be built.

2. Reduction in the above-ground built form, through a lowered ridge and fragmentation of the overall mass. The architectural approach preserves views from the Swaylands Estate into the landscape. This approach will preserve the heritage setting of the park and garden.

3. Incorporation of a basement plinth allows for a sensitive response to levels. Yet it is also a playful response to the rockery. Cut and filling of the Site would appear just that and levels are not controlled through the existing fallback position. That allows a considerable degree of damage to setting. Placing the house on a stone basement plinth and allowing parts of the house to rest over the existing rockery ensures an elegant solution to levels and the protection of setting.

4. A basement allows for the reduction in hard surfacing above ground and within the registered park and garden. Vehicles would appear as residential paraphernalia.

Basement parking removes cars from the landscape. That leaves the architecture and heritage asset to sit together without interference.

5. The architectural approach represents a bold, yet subtle design solution building on the concepts of the rockery and registered park and garden. It reinterprets the ideas of Kentish architecture and the immediate setting in a 21st Century manner. The result is exemplar architecture that sits comfortably within its environment, linking inside to outside and responding to and informing its surroundings.

The approved dwelling is not, in hindsight a sensitively designed and well-mannered building that integrates elegantly into the surroundings. Instead, it is a pastiche dwelling at odds with the historic parkland and rockery that materially damages its setting.

One way or the other, a house will be built on this site. The approval of this dwelling was wrapped up in the larger application for the main Swaylands house. The carving out of this plot of land from the larger estate and the dwelling to be located on it was not rigorously inspected. Therefore the approval offers the council and local residents little to no control over several highly important aspects that impact neighbouring properties and the historic context.

There is a limited opportunity to revisit the decision and seek approval for a new design that represents exemplar architecture that accords with the National Planning Policy Framework, is of reduced impact on Swaylands residents and is more sympathetic to the site context and history.

Approved scheme site footprint.

• Does not respect historic routes through the site.

Above: Lakeside house approved site plan under planning application SE/02/01110/FUL

• Allows for cars to pass between the upper and lower rockery.

• Creates formal gardens in the historic parkland setting • Is highly visible from Swaylands due to its heights and large brick chimneys.

• Large windows at 1st floor facing Swaylands means that it will be highly visible at night.

The site is a significant heritage asset in its own right. The financial burden of maintaining and enhancing it will be substantial over time. Considerable financial means are required to protect the rockery into the future. The proposed new design is far more desirable than the approved scheme whilst being more respectful to neighbours and the overall context.

• Significant harm to the heritage asset setting as large, raised decking runs parallel to the lower rockery wall.

• Proximity of the dwelling to the rockery creates an inharmonious discord between two forces Above: Lakeside house North elevation facing Swaylands approved under planning application SE/02/01110/FUL

competing for dominance.

Through a reduction in the above-ground built form, a lowered ridge and fragmentation of the overall mass the new architectural approach better preserves views from the Swaylands Estate into the landscape, preserving the heritage setting of the park and garden.

5.0 New AV Architects Proposal 5.1 Design Statement As creators of physical objects, it is our great responsibility to become observers of nature and our surroundings. Buildings provide for the basic human needs of shelter and comfort but, they also need to respond and interact with their natural environments. The best homes meet practical needs and stir the emotions through their artistic form and response to their context.

The approved scheme copies architecturally what has gone before and is falsely constrained rather than liberated and responsive to the sites physical and historic context. The environment where the dwelling is proposed is not untouched by human hand. It is the artistic, romantic creation of a previous owner of Swaylands, George Drummond in the early 20th Century. Rather than creating a dwelling which ignores the unique man-made context, our design celebrates the unique nature of George Drummonds vision with a home that playfully interacts with the rockery but, never loses sight of the importance of the wider landscape that lovingly interacts with the architecture.

With this in mind and with careful historical studies we propose to mould our addition to the natural environment through the creation of vertical and horizontal frames (as we have been doing every day for thousands of years). Our architecture is silent however, one can sense rhythm by passing alternating solids and voids in the facade. These facades mimic greenery in the earlier stages of growth, dividing solid and transparent elements to create continuously changing experiences via framed vistas through the building to the natural environment beyond.

May 2021

20007-DAS.pdf

Views that change with time and season create varied, intimate journeys through the built environment and out to the wider external landscape.

The proposed home is orientated to make the most of the vistas outward from the site but also the views within the site of the boat pond and rockery. With a more horizontal emphasis than the approved scheme and material palette of natural tones the building is intended to blend in and slowly reveal itself to the onlooker rather than being the dominant form on the site. This more responsive approach also means that there is reduced impact on the residents of the apartments at Swaylands above the proposed house or Swaylands School Farm below.

Proposed scheme site footprint.

• Blending and revealing as explored.

• Designed exclusively for the site.

The proposed design has a delicate touch, blending together the natural and created forms. The building and landscape become one to create not only a home but also a gallery of views and enclosed safe spaces for contemplation, reflection and art. The proposed building coexists with nature. Having a design “of its time” expresses how important it is to have a fresh voice and restore the natural beauty of the site through investment in the new, whilst renovating and respecting the creative force of those that went before us.

• Lower ridge height than approved scheme.

• Natural palette of materials • Created following site and historic studies.

• Restoration of historic routes and rockery.

The soul of this proposed building is an attempt to create an important symbiosis between human creation and the parkland setting. Like water allowed to engulf and swallow a vessel, the architecture is intended to drown in the wild grass and flower meadow to finally become at one with the surroundings.

5.2 Response to the site When developing the design for a new dwelling we consider our clients spatial requirements and whether it is a realistic proposition given the size of the plot and planning policy, then the next step is to consider how we create balance between:

• The desire to relate the dwelling to features of the site without lessening those site features in the process.

• How internal and external spaces we create could relate to sunrise and sunset and how this changes with the seasons.

• Where are the best views outward from the dwelling and what is the best vantage point height to take full advantage balanced with any conflict created with views back to the site from outside.

• Aspect and Prospect of the building from differing location.

During the research stage into the commission there have been two pieces of text written by others that we kept coming back to as inspiration for the design: In the Country Life article of 1906 about the rockery gardens the author wrote

21st December - Winter Solstice

The Sevenoaks District Council Conservation Officer Regina Jaszinski when considering a previously submitted design for a dwelling on the site wrote about the overall landscape design of the original Swaylands gardens

‘Not a tree or shrub that possessed interest or beauty has been destroyed in the making of the rock garden..’

The rocks have been placed around the trunks of mature trees which will have given an instant sense of maturity to the garden’.

‘Being located on the slope of a hill, the garden is designed as a sequence of large terraces, lawns and rock gardens that gradually reveal new views and glimpses as one traverses from the north towards the west and south.

The listed garden contains areas of distinct character on different levels, such as the formal terraces adjacent to the house, pleasure grounds including the large expanse of the former cricket pitch to the south-west, rockeries and two ponds, one of them formerly a boating lake’.

There has been a great deal of in-depth documentation written about the site from a heritage, ecological and arboriculture standpoint. All these documents were studied and their recommendations incorporated into our design thought process of how the proposed building would relate to the site context.

A full sun path analysis of the site took place to establish the movement of the sun through the sky across the site at different times of day and season. This was to help our thought process as to where rooms could be located to take the greatest advantage of vista, site features and natural light.

Design and Access Statement

Lakeside House

As approval already exists for a dwelling in a particular part of the site we considered whether this was the right location. It became apparent very quickly that it was the only suitable location for the dwelling which was contained by the pond and rockery to the east and the Ha-ha wall to the west.

53.00 52.00 51.00

Although relatively flat from east to west from north to south where the dwelling is proposed there is a 3.5m change in level from one side of the site to the other that seems to have been ignored by the previously approved scheme. As a designer there needs to be a decision as to whether the building is pushed into the ground on one side with a new retaining structure required or allow the building to float above the landscape.

2. The site benefits from an amazing view out to the Medway River valley and inward to the boating pond.

3. The plotting of these lines on the site create nodes that are used to develop the design concept plan.

The above design concept plan was created based upon: • Two pavilion buildings running parallel to each other. One taking advantage of the view out of the site the other the inward view over the boating pond.

• A circular form like a roundel is added with the idea that this will be the buildings principle entrance and vertical circulation.

• The decision is taken that the main accommodation block should run perpendicular to the rockery which has the benefit of making the entrance area a courtyard closed on three sides.

• The accommodation brief includes for a swimming pool which we feel should sit below the building, easily accessible but subtle and understated.

These three points led us to recall a building called Goulding House in Co. Wiclow near Dublin designed by Dr Ronald Tallon and built in 1972 that cantilevers over the River Dargle.

Mr Robert Porritt

Design and Access Statement

Lakeside House

Goulding house - 1972 Goulding house is a detached three-bays wide and five bays deep single-storey modernist style cantilevered summerhouse on the well-wooded banks of the River Dargle in Co. Wicklow, Ireland. It was built in 1972 to designs by Dr Ronald Tallon.

Influenced by the works of Mies van der Rohe and the Frank Lloyd-Wright house Falling Water the building is a stark and angular steel-framed flat-roofed ‘box’ structure supported on steel stilts with the panels of the steel skeleton either glazed or filled with cedarwood cladding. The front and river facing elevations are wholly glazed, the former incorporating a central doorway.

Both directors of AV Architects worked in the 2000’s at Scott Tallon Walker Architects in Dublin. Neil Edwards worked personally with the designer of Goulding House Dr Ronald Tallon.

At the application site when reviewing the levels around the rockery, the proximity of the adjacent mature trees and the aesthetic that the pond would offer once cleared of Bulrushes it recalled visits to Goulding house and the wonder of floating in the canopies of trees over water.

We do not propose to have a pavilion that cantilevers over the pond to the extent that Goulding House does over the River Dargle and there would be 2.6m from the underside of the pavilion structure to the lower rockery terrace but we do feel that there is an opportunity to create a subtle modernist pavilion that floats over the rockery and nestles next to the retained mature trees together with the planting of other mature specimen trees on the other side of the proposed pavilion. The structural design that avoids interference with the rockery is covered later in this document.

The quality of Goulding House and the need for it to be protected for future generations was recognised with its listing in 2003 by the National Inventory of Architectural Heritage.

Fallingwater - 1937 One of Dr. Tallons inspirations was Fallingwater.

Frank Lloyd Wright designed Fallingwater in 1935 for his friend Edgar Kaufmann, and completed it three years later. The client asked for a holiday home for his family that faced the 30-foot (nine-metre) waterfall of the Bear Run Nature Reserve in rural Pennsylvania, USA. Taking cues from the rock edges, the American architect cantilevered floors from the house’s three levels. Occupied by a series of terraces wrapped with reinforced concrete balconies, these project over the water’s edge at the rear and the wooded valley on the other sides.

Since 1963, it has belonged to the Western Pennsylvania Conservancy, which now run it as a museum. From 2012, the house has been used for a series of summer camps to teach skills in architectural problem-solving to high-school pupils and schoolleavers hoping to study architecture at university. A series of dwellings were recently completed nearby to house these residents.

Fallingwater is often referred to as one of Wright’s masterpieces. In 1991, the house was named by the American Institute of Architects as the “best alltime work of American architecture”.

It was one of 10 of the architect’s buildings nominated for the UNESCO World Heritage List in 2015.

Both Goulding House and Fallingwater are buildings that have been introduced into natural settings. Lakeside house is different in that the setting is a man-made one. The proposed design interacts visually, but does not have any physical connection with the rockery.

5.5 Inspiration from the local.

The majority of the nearby Grade II Listed Swaylands as it appears today is dominated by the Neo Tudor extensions to the original villa that were added at the end of the 19th Century. This is such a strong, distinct style typified in the houses octagonal battlemented tower, and 2-storey battlemented parapet.

We believe it would be out of place and time to try and create a “Mini Swaylands” in the Tudor style on the development site. However, we are interested in the tone of brick used and also a modern take on polychromatic brickwork

As a subtle recognition of the sites connection to Swaylands we have incorporated the same brick tone into the entrance rotunda. A de-constructed polychromatic brickwork scheme is incorporated via a modern pixelated design projecting forward of the main face of brickwork. Wrapping around and down the rotunda in an organic cascade it is incorporated into both sides of the rotunda to add a decorative element inspired by the nearby listed building.

Note: Polychrome brickwork is a style of architectural brickwork wherein bricks of different colours are used to create decorative patterns or highlight architectural features in the walls of a building May 2021

5.6 Inspiration from the regional.

K S

The most iconic or Kentish vernacular architecture: oast houses, consist of two separate forms called kilns and stowage.

•

Kentish oast houses consist of a rectangular one or two storey building (the “stowage”) and one or more kilns in which the hops were spread out to be dried by hot air rising from a wood or charcoal fire below. The drying floors were thin and perforated to permit the heat to pass through and escape through a cowl in the roof which turned with the wind.

•

Where we have the intersection of the access route and outward and inward site vistas we propose to take inspiration from the circular form of oast house roundel kilns and create a brick rotunda to house the dwelling main entrance and staircase. We wish to keep the height of the building down as much as possible to ensure there is no impact on Swaylands and therefore propose to have a circular glass roof light over the rotunda rather than a traditional roundel roof and cowl.

•

The main accommodation block will be the stowage element of the composition. Inspired by dark stained timber clad stowages the facades will be articulated with vertical framing elements creating an aesthetic taking the slatted drying floors of the kilns as shown in the image above to create an articulation to the facade and introduce a greater level of solidity.

Roofing and Brise soleil Corten Steel.

Considered use of glass and fenestration design.

Due to its warm hue of burnt-orange tones that blend well with greenery and vegetation we propose to use Corten steel for the main roofs of the proposed dwelling and the brise soleil that wraps down the north east facade.

Glass is not only a remarkable material in terms of appearance, but also due to its design flexibility. Panels can be manufactured in various shapes and receive various different coatings and treatments.

Corten—or weathering steel—is typically used for landscaping and outdoor construction. It is made with alloys that cause its surface to develop a selfprotecting rust when exposed to weather. The insulating patina resists corrosion, requires no painting or weather-proofing, and doesn’t compromise structural strength.

Architects and designers especially appreciate the material due to the following assets it provides: • Combination of strength and durability with minimal thickness, resulting in the creation of fine, elegant solutions for the outdoor space.

• Generally available in sheet and plate form, facilitating the process of construction.

• Natural, warm, and specific hues, which easily blend into the overall landscape and add to the identity of a unified site.

May 2021

20007-DAS.pdf

At Lakeside house we intend to balance competing requirements: • The desire for views out from the building vs others privacy • Maximum amount of natural light entering the building vs limiting light pollution at night.

The proposed design has no large areas of glass facing Swaylands or Swaylands School Farm. The majority of glass is at the ground floor which should not be visible from Swaylands due to the height difference.

The windows at upper floors are recessed deep into the facade to limit light spillage at night or are contained below the roof overhang. Artificial lighting in the house will all be warm LED and be connected to PIR sensors to ensure lights are not left on with no one in the room.

Further details in regard to measures to limit light pollution from the proposed dwelling are contained within Alan Tulla Lighting - Lighting strategy document for Lakeside House 53

AV Architects have used Sto Ventec Glass in RAL 9022 with a Stopsol Susi solar film on various prestigious projects including the contemporary extension of Grade II listed Crouchers Cottage that can be see above.

We specify Equitone due to its flexibility of use and unique natural look.

When Ludwig Hatschek invented fibre cement in the late 19th century, he combined the basic elements of the earth: mineral materials, water, air and fire (heat) in a simple filtration process. He named the resulting material “Eternit”, hinting at the superior durability of this new material. The Hatschek production process makes each Equitone facade panel unique with an individual fibre cement texture.

20007-DAS.pdf

At Lakeside House In order to create the illusion of the building floating or being engulfed by the landscape we propose to clad the base plinth in Sto Ventec Glass at an obtuse angle so that it reflects the grasses and wild flowers below it but there is no risk of glare or unwanted reflection. The artists impression on page 52 shows the effect created to the side of the steps up to the raised terrace.

StoVentec Glass is a ventilated rainscreen cladding system consisting of a glass faced composite panel, thermal insulation and sub-construction. Tempered safety glass is adhered to a carrier board to produce an inseparable composite panel, which protects the stainless steel, aluminium sub-construction from rain. A circulating air layer is formed between the hung panel and the mineral wool insulation, mounted directly onto the substrate. Insulation on the outside of the construction keeps the wall warm and reduces the risk of condensation and minimises temperature fluctuations.

Facing brickwork

Zinc roofing Zinc roofing.

Facing brickwork

Zinc roofing is popular for its durability, life-span and weathering. It is also relatively lightweight and has the flexibility to work with most roof shapes in a way that would be impossible with traditional tiles.

The circular form of the brick entrance rotunda is in reference to the roundels of oast houses, the most quintessential Kentish vernacular architectural form.

The roofs at Lakeside house where we propose to use zinc have simple geometry but need to balance the overall quality of the building and setting. Zinc is proposed to the two flat roofed pavilions either side of the main accommodation block and to the lower butterfly roof over the day room.

As a subtle recognition of the sites connection to Swaylands, we have incorporate the same brick tone into the entrance rotunda. A de-constructed polychromatic brickwork scheme is incorporated via a modern pixelated design projecting forward of the main face of brickwork. Wrapping around and down the rotunda in an organic cascade it is incorporated into both sides of the rotunda to add a decorative element inspired by the nearby listed building.

Zinc is a Sustainable Resource Zinc, with its key attributes of essentiality, durability and recyclability, is well positioned as a material of choice for a sustainable society.

5.8 Scale and Massing Our proposed design is more permeable and the overall height is lower than the permitted houses which therefore reduces its impact and creates greater openness.

As with the rockery garden, due to the buildings considered design and given form, opportunities are created for managing views to create intrigue and exploration.

The figure-ground diagrams to the right show the buildings comparable footprints at first and second floor levels.

The proposed designs bulk reduces substantially as it gets higher whereas the 2002 scheme remains relatively constant.

The two designs take very different approaches to the site.

The approved scheme imposes itself on the site with no consideration to the sites topography or opportunities. It wishes to be seen and to dominate the natural environment.

The approved scheme is highly detailed in the Victorian style and would appear to be a good example of taking a style from the past and trying to re-create it over 200 years later. The difficulty is in ensuring in execution it retains the level of detail displayed in the approved planning scheme.

The other concern is that a building which is not of its time will always appeal to a limited audience. We believe our scheme is more subtle in that it responds and respects the site, marries together the natural and the managed worlds and is intended to reflect a fusion between traditional Kentish vernacular and contemporary 21st century architecture

South Elevation

The above graphic elevation shows the proposed design with the outline of the granted scheme superimposed over in red.

At the first floor there are three solid forms numbered 1 to 3 above. These are: 1 - Sleeping accommodation contained within the Equitone clad block. 2 - The central brick rotunda. 3 - Equitone clad cinema room to the right. As can be seen the heights of these three elements vary in height to reduce the perceived mass. The separation of the three elements and the use of glass ensure permeability through the building to the landscape beyond as does the high use of glass at the ground floor.

The new designs mono pitch roof is 500mm below the top ridge of the granted scheme the second floor is set back from the edge and the majority of the facade is glazed. Therefore the main visible bulks will be the Equitone clad block which runs perpendicular to the rockery wall which is 4.3m below the highest ridge of the approved scheme.

2 1. On entrance to site a space was spotted between mature trees that appeared ideal for a floating pavilion structure with a backdrop of trees and the rockery.

The pavilion could be missed by observers as it nestled between trees much larger than its own form.

2. Continuing into the site the vista opens up with views towards the rockery and down into the valley.

3. From the middle of site there are wonderful views east towards the river valley.

4. Further investigation of context together with impact on neighbours revealed that a built form working around the emotional response to the site could produce a highly unique scheme of balance and originality, fitting of such a magical setting.

Built footprint density

Emotive response to the site May 2021

The building density increases as you progress further into the site: 1. Single storey refurbished boat house 2. Single storey flat roof pavilion structures 3. Two storey block 4. Rotunda containing vertical circulation 5. Main accommodation block running perpendicular to the rockery wall to ensure maximum visibility of the rockery and limit the impact on the view from Swaylands to the wider landscape.

5. The layout creates the opportunity to introduce a contained arrival courtyard with new specimen tree as its centre point.

1. A strong visual connection to the landscape beyond is retained via a framed view to the side of the pavilion.

2. Views through the building to the landscape beyond.

3. Glass panels either side of the rotunda allow for framed views of the rockery beyond.

4. The mature oak tree is used as an anchor for the pavilion structure that cantilevers out over the lower rockery wall and is glimpsed between the built forms.

5. There is a generous distance from the rockery wall to the building but the use of glass and site levels ensure that the two structures appear like terraces in the landscape.

20007-DAS.pdf

Openness and containment

Permeability at ground floor May 2021

There is very little solid structure at the ground floor since the majority of the external envelope at ground floor is glass. This is reversed at the first floor with the majority being solid walls with less windows facing Swaylands than the previously approved scheme.

The locations of the built forms ensure there is the right balance between openness and containment of the managed environments.

1. The pavilion floats above the landscape but the wall that faces the arrival point is solid to contain the space to more comfortable proportions.

2. Openness zones are created that are numbered. Higher numbers are more managed.

The upper terrace is proposed to be of very low apparent management from the point where it is accessed via the pavilion building.

3. Openness wraps around the building from the view to the valley to the rockery wall.

4. The arrival point is the most managed of the open environments and is contained between the buildings, mature trees and rockery wall.

5.10 Artist impressions of the proposed design.

•

The contemporary designed home is approached via a wonderful sweeping driveway that allows for glimpses across the lake, through the retained mature trees of the home and pavilion structure.

•

The home seems to float above the landscape with a high level of permeability to allow for views through to the Kent countryside beyond.

•

Inspired by the simplicity of the rockery gardens, the landscape although designed will be modest to reflect the rugged nature of the rockery and the relationship between the angular architecture of the home and transition from managed to natural environments. Careful thought has been given to how the building is located on the site to respect the existing trees, rockery walls and the connection of existing routes that permeate the rockery wall.

•

The home is complemented by a pavilion structure that is accessed via a suspended bridge that spans between the two structures.

The pavilion nestles to the side of retained oak trees and cantilevers over the existing rockery wall.

•

The home is designed to provide a unique living experience and is carefully thought out to ensure that all spaces provide for unique emotional responses depending on mood, time of day or season.

The elevation facing the Medway valley has large areas of glazing at the ground and second floors (screened by Equitone blades) separated by the strong Equitone clad block containing the majority of the homes sleeping accommodation at the first floor.

•

The homes external swimming pool is located in a walled garden that is located at the homes basement level clad in Calacatta Marble. In this way the pools landscape impact is limited but it is conveniently located for access from the homes ground floor and rear landscaped meadow.

•

The roofs over the main house and the single storey family room are gently pitched to suck the vista into the home.

•

The small single storey pavilion to the right of the image acts to enclose the space at the front of the house and provides a viewing platform from which to enjoys the sunset in the summer as the sun disappears over the mature trees at the sites western boundary.

All elevations have been carefully designed to ensure the appropriate use of materials to break up the apparent mass of the building and provide the right level of permeability through the building to the landscape beyond.

•

There is a reason behind the location of every element of the buildings composition as it relates specifically to the site with the buildings form creating the same sort of intrigue and surprise as the rockery garden.

•

The home and the landscape are perfectly in sync with the built form designed to allow continued permeability through the site and for the occupants of the home to easily enjoy and access the rockery garden.

Paul Molineux Associates structural engineers were asked to prepare a structural strategy for the pavilion that cantilevers over the listed rockery wall. Below and on the following page is the text and structural information prepared by Ben Tubb of PMA.

Roof structure

6.1 Structural design philosophy The structural concept has been considered in the context of avoiding any damage or impact on the long-term stability of the listed rockery. The large cantilever and open nature of the superstructure lends itself to a steel frame design. The superstructure and cantilevered terrace can be formed from a skeleton of steel beams and columns with timber or masonry infill. For the ground floor inside the building a suspended ‘beam and block’ floor will provide a solid platform as well as offering the advantage of additional weight to resist the uplift generated on the beams supporting the cantilevered terrace. Piled foundations would be recommended for the foundations located away from the rockery to avoid surcharging the rockery structure. Augured piles will be specified rather than driven piles which can be installed with minimal vibration and noise and would be installed far enough behind the rockery wall as to not pose any significant risk to its integrity. PMA would liaise with the piling contractor to ensure the piling rig is no larger than necessary to ensure the integrity of the rockery is protected. It is anticipated a ‘mini’ piling rig would be used which generally has a footprint no larger than a small van. It is expected that piled foundations will be used for the remainder of the structure away from the rockery, though more traditional shallow foundations may be an option subject to detailed soil investigation works.

7.0 Lighting strategy Alan Tulla, FSLL, FILP, a Fellow and Past President of the Society of Light and Lighting and Fellow of the Institution of Lighting Professionals, lectures for them on the topic of exterior and amenity lighting.

He is author of the Society of Light and Lighting “Guide to the Exterior Environment”.

Alan Tulla lighting was asked in April 2021 to prepare a comprehensive guide on how to minimise the impact of the lighting at night-time and any possible light pollution. The main report accompanies this application but the main points can be summarised as: External lighting •

Site considered to be an E1 Environmental Zone. The ILP describes this as “Dark environment, relatively uninhabited rural area, National Park, Area of Outstanding Natural Beauty, International Dark sky Association buffer zone”.

•

Upward light must be kept to a minimum or, preferably, avoided altogether.

•

Only LED light sources which emit little, or no, UV should be used. This is one of the main recommendations in the Bat Conservation Trust, BCT, document “Bats and Lighting in the UK” 2018. This Clientwill AV Architects ensure that the outdoor lighting is sympathetic to the ecology of its surroundings.

•

The main external lighting will be provided by bollards which emit no upward light.

•

Recommend LED light sources with a colour temperature, CCT, of Warm White, preferably 2700K

•

Where there are steps or changes of level, recessed wall (or in the stepped stone terraces), mounted units with horizontal louvres should be used. This will block any upward light and provides extra Rev security to the residents where the ground is uneven.

Internal lighting

Report Lighting strategy for proposed private house at Lakeside, Sw

Date 21 April 2021

•

Much of the internal illumination at night will not be seen due to the setback of the windows and the overhanging roof.

•

Rooms are controlled by PIR presence or absence detectors to limit lights being left on accidentally

•

The natural setting of the house and the move towards lighting that follows the pattern of daylight means that the report suggests the use of variable colour temperature (CCT) LEDs. Rooms can appear cooler in the morning and have a softer, warmer appearance with lower levels of illumination in the evening. Programming and scene setting can be linked to an astronomical clock which thus alters the timing throughout the seasons of the year and length of day.

1. The drive surface to be 75-100mm lower than the adjacent ground levels, whose levels will be retained as existing.

2. The design of the arrival area outside the entrance rotunda would be a sympathetic circular form. The central focus will be a new native tree.

3. The lake, surrounding landscape and the historic walls will be conserved and restored as faithfully as possible, with reference to the archival information included in the Landscape Heritage Statement.

7 2

4. The lake itself would be de silted (carefully to avoid damaging the liner) and its early 20th century extent reinstated, with some aquatic planting (lilies, iris). The surrounding walls and paths dating to the early 20th century would be carefully exposed, repaired and reinstated.

Surviving original planting will be retained and managed as required by good horticultural practice (formative pruning, re-shaping, coppicing etc.).

5. New mature tree planting will be located on the northern side of the music pavilion to make the cantilevering terrace nestle between the tree canopies and float over the rockery.

6. The planting around the boating lake would be restored using the evidence in the Landscape Heritage Statement, i.e. contemporary descriptions, photographs and plant lists. Along the south of the lake informal clumps of planting are proposed to ensure views south are kept open and the historic character retained. Refer to the Landscape Management and Maintenance Plan.

6 7

7. The landscape design around the house and in the western part of the site would be deliberately simple and meadow-like in character. This is partly to contrast with the texturally rich design around the boating lake; also to take in the wonderful views to the south and west.

The early 20th century ha-ha wall and ditch would be carefully restored to allow views out from the garden over the parkland (native species wildflower meadow and the wider landscape to the west). At the southern end of the ha-ha, level ground will be retained to allow access to the parkland from the garden

•

Parkland estate railings (fiver bar horizontal mild steel railings, either painted black or left untreated), with gates to match will be installed along the north boundary of the parkland.

•

The existing hedgerows along the west and south sides of the parkland will be retained and gapped up as necessary with a similar mixed native species mix (50% hawthorn, 15% hazel, 10% blackthorn, 10% dogwood, 5% guelder rose, 5% holly, 5% dog rose and crab apple).

•

Within the garden, some grass areas would be wildflower meadow for added nature conservation interest, with five hibernacula included for newts and reptiles.

Proposed materials •

Drive: loose rolled gravel (10mm flint pea shingle) over a blinded Type 1 subbase. On the steeper section a bonded gravel over bitmac surface will be used (2-6mm Thames gravel).

•

Paths: loose rolled gravel (10mm flint pea shingle) with steel edging.

•

Paving: natural riven sandstone.

•

Walls: as existing (yellow/buff sandstone).

•

Lawn: all areas will be relaid with new turf, with drainage where necessary.

•

Meadow: the parkland will be managed as a flowering meadow (80% locally occurring wildflowers and 20% meadow grass).

9.0 Ecology and Biodiversity 9.1 Great Crested Newts As part of previous submissions a Great Crested Newt Presence / Absence environmental DNA Assessment was conducted by The Ecology Co-op environmental consultants and a report created dated 24th July 2015.

The e-DNA test that was conducted at the time identified the presence of great crested newt environmental DNA in the pond. This suggests that the pond was supporting a breeding great crested newt population. There is no reason to believe that this is not still the case particularly as in 2015 when the survey was completed the report lists that the pond was 95% covered by bulrush (Typha latifolia) which is still the case today.

The document prepared by The Ecology Co-op described the site as being set within a rural landscape surrounded by arable farmland, woodland and small fields of pasture within the wider landscape.

May 2021

20007-DAS.pdf

The site was listed as comprising of seven habitats; 1. Broadleaf woodland – Semi-natural 2. Scrub – Dense/continuous 3. Broad leaved parkland / scattered trees 4. Neutral grassland – semi-improved 5. Pond 6. Buildings

Should planning permission be granted for the proposals a license will need to be applied for before any development work can begin.

Due to the close proximity of the pond to the development area, a high degree of mitigation measures would need to be implemented as well as population assessments conducted on all of the three ponds (assuming that access is granted to the two ponds ‘off-site’). A mitigation statement would be created outlining the various steps to be taken to ensure the population of GCN is not only maintained, but all individual newts are protected from harm.

7. Bare ground.

The broad leaf woodland and scrub vegetation surrounding the eastern edge of the pond and the semi-improved neutral grassland to the west provides habitat of value for great crested newts.

The habitats to be lost due to development would be most of the semi-improved grassland and the scrub / woodland. The vegetation immediately surrounding the pond including the scrub habitat and the small woodland to the southeast would remain intact.

9.2 Improving and creating new habitats The development of the site provides a great opportunity to enhance the pond and to enable it to better support the great crested newt population, as the near total cover by bulrushes is not particularly good for breeding newts. As part of the proposed landscape works at least 80% of the bulrush (Typha) would be removed allowing for the planting of native aquatic vegetation to provide more areas for newts to lay their eggs.

10.0 Sustainability The design aims to be timeless, using the highest quality materials possible but with minimal impact on the environment. Environmental sustainability is a core thread running through the National Planning Policy Framework, Sevenoaks District Council and the High Weald AONB Management Plan.

Sustainability is fundamental to the scheme, the building is oriented on the site with close attention to the landscape context, topography and sun path. We recognise the potential for the dwelling to contribute towards an improved environment and are committed to raising the environmental standards of the site.

10.1 Materials Corten steel used for roofing, soffits, decorative window surrounds and brise soleil.

Corten is a sustainable choice, with no maintenance required the surface develops to a stable rust-like appearance. Allowing the steel to rust makes the rust itself form a protective coating that slows the rate of future corrosion. Corten steel’s corrosion resistance performance is 8 times higher than ordinary steel with no need to spray antirust paint unlike common steel that must be primed and sprayed with paint to get to the desired aesthetic look. Generally anticorrosive paint will need to be applied again after 20 years. Naturally, Corten steel can be used for 80 -100 years without any painting or surface treatment. Corten steel can save raw materials, reduce reconstruction, painting and secondary operation pollution, with no maintenance costs required.

As a family run business AV Architects passionately believe in sustainability to meet the needs of the present without compromising the ability of future generations to meet their own needs.

Equitone EQUITONE is produced with mainly locally sourced materials and actively minimizes energy and water usage during production. The EQUITONE materials require low maintenance and have a long life expectancy. Sustainability goes beyond the material and the manufacturing process. All EQUITONE materials support lightweight construction, which helps to achieve an overall low carbon footprint of building projects. Our fixing methods are disassembly proof, and the panels are 100% recyclable. The use of EQUITONE materials is supportive in creating more sustainable projects.

Facing brickwork for rotunda Brick is a natural, quality, user and maintenance-friendly product, that is durable during all phases of its life cycle.

In the construction phase from the use of raw materials, production process to packaging. During the operational phase through comfort, maintenance, flexibility and safety. During demolition through reuse and recycling of bricks.

We will be trying to locally source suitable reclaimed brick for the facing brickwork on the project.

Sto Ventec Glass Sustainability and energy efficiency are as much a part of future oriented planning as a solid architectural concept.

Sto’s Building with Conscience mission influences the materials they use to help them gain BREEAM credits.

Glass façades are extremely hard-wearing and weather-resistant. The carrier boards for the panels are manufactured using expanded glass granulate, an environmentally friendly material that is produced from 96% recycled glass.

Zinc roofing to flat roof pavilions and butterfly roof over the single storey day room Zinc is a Sustainable Resource. It can be recycled infinitely without loss of properties and quality. While the recycling rate of zinc depends mainly on the collection rate of zinc-containing products at their end of life, over 90% of these collected products are recycled. Zinc is extremely durable and its carbon footprint is substantially better than other metal cladding materials. Zinc, with its key attributes of essentiality, durability and recyclability, is well positioned as a material of choice for a sustainable society.

10.2 Structure Basement The structural solution is designed to create the right balance between longevity through robustness and the carbon footprint of the selected solution. The best form of sustainability is the creation of a design that is timeless, a design that matures into the landscape which we feel our design will achieve.

The topography of the site with its 3.5m slope from north to south lead to it being logical to add a basement to the design as the upper northern level is used for the ground floor plate therefore the basement is less “out of the ground” at the southern end.

For the construction of the basement there are limited solutions and most involve the use of reinforced concrete as the principle structural element . At the current stage of development of the project we consider that for the creation of the basement walls the best structural solution will be to use Durisol woodcrete ICF that are then filled with reinforced concrete and to have external waterproofing and an internal drainage cavity.

Manufactured in South Wales environmentally the ICF forms use recycled material, softwood aggregates that are by-products of the timber industry. In terms of resource depletion and carbon costs, the net cost is approaching neutral. Whilst cement is used during production and in the construction of the walls, there are various compensating factors which reduce Durisol’s carbon count to below most traditional methods of construction.

•

An average 3-bed semi-detached house built from Durisol will have 10 tonnes of recycled wood in the product. This wood is made up of old pallets and offcuts which would have been destined for landfill and consequently would have released carbon back into the atmosphere.

•

Once the waste wood is mineralised and encased in cement, it won’t rot or burn. In effect, the embedded carbon is permanently captured and locked in.

•

Durisol wall form units are manufactured by moulding onto the factory floor and they then set at room temperature – there is no requirement for extra energy to warm the units.

Super structure The use of structural steel and concrete will be limited as much as possible with timber being used wherever practical. For the external wall and roof structures our proposal is to use Structurally Insulated Panels (SIPS).

The environmental benefits for the project of using SIPS are: •

There are a number of SIPS manufacturers in Kent so we can source a local supplier.

•

Light-Weight Structural Strength - The average weight per sqm of a Structural Insulated Panel is 20kg.

•

SIPS use ODP zero insulation for the core and OSB/3 faces made from sustainable forest resources.

•

Excellent Thermal Performance - U-value as low as 0.10 w/m²k, limited cold bridging and superior air tightness.

•

Save Construction Time so people are on site for a shorter period of time - Large engineered components.

10.3 Renewable Energy and Energy Efficiency Ground Source Heat pump There is sufficient land in the lower meadow to install a ground source heat pump with minimal impact. Once the installation process is complete after a short period of time the meadow will return to its previous natural state so it will be impossible to know that there is a renewable energy system below the ground.

A ground source heat pump transfers heat from the ground into buildings. Radiation from the sun heats the earth. The earth then stores the heat and maintains, just two metres or so down, a temperature of around 10°C even throughout the winter. A ground source heat pump uses a ground heat exchange loop to tap into this constantly replenished heat store to heat buildings and provide hot water. The technology used is the same as that used in refrigerators. Just as a fridge extracts heat from the food and transfers it into the kitchen, so a ground source heat pump extracts heat from the earth and transfers it into a building.

For every unit of electricity used by the heat pump, three to four units of heat are captured and transferred. In effect this means a well installed ground source heat pump can be 300-400% efficient in terms of its use of electricity. At this efficiency level there will be 70% lower carbon dioxide emissions than for a gas boiler heating system. If the electricity is provided by renewable energy, then carbon emissions can be reduced to zero.

10.4 Thermal performance and Heating The main source of heating for the house will be provided via the ground source heat pump installation.

The home is located to maximise the potential of the sun’s path. The house will be kept warm using super-insulation and passive solar gains through the south, east and west windows. The dual aspect kitchen catches the morning and afternoon sun all year round. The benefit of the ground source heat pump is that is can be put in reverse in the summer to provide chilling of the floors.

The semi subterranean aspect of the building with the basement accommodation means that thermal massing becomes a key feature, helping to keep the interior warm in winter and cool in summer.

10.5 Water and Drainage

10.6 Health and well-being

With the use of efficient A rated white goods, dual flush WC cisterns and taps with flow restrictors and aerators, internal potable the intention is that water consumption will be kept at 80 litres per person. In order to reduce treated potable water use, rainwater harvesting is proposed so that rainwater from roof surface areas can be used for the irrigation of the Landscaped Garden areas.

The orientation of the home, to make the most of the sun path and high use of glazing to the spaces used during the daytime, reduces the need for artificial lighting to the dwelling.

Research has shown that there is a big positive impact on human beings of good natural day lighting. Adequate access to daylight will contribute to the Health and Well-being of the dwelling occupants providing them with a pleasant living environment.

The provision of secure private space is an effective way to improve the quality of the occupier’s life.

The varied private spaces around the dwelling and wider site offer multiple types of environmental stimulation. External spaces can be used by the occupant as a secure playing space for children, for horticultural purposes or simply as a convenient place to relax and take in the fresh air and enjoy the scenery.
