Introduction Sitting on the edge of the centre of Duddingston, the community orchard, “the Field”, connects the urban grain to the wild. With Arthur’s Seat and its neighbouring hills encompassing the orchard, there comes an opportunity to explore. The current social and environmental climate is constantly pressing for more sustainable and local options for food and resources. Entwined with the human desire to explore, the activity of foraging and farming arises. The community orchard known as the Field accommodates the need for locally grown produce, as well as the nearby community garden. The new development will be an addition and an exploration into the activity of foraging and sustainable production in the orchard. Several desire lines are present in the site, ones which must be respected and integrated into the design, allowing the structure to become part of the foraging pilgrimage. Within the building, foraging workshops will be held, as well as an opportunity to purchase foraged products.

The Anchors As a group, we initially recognised the edges and anchors of Duddingston, focusing on the central core of the village. By defining the “anchors”, points of interest were made for each individual and thus a masterplan was produced. The Loch Edge, Thompsons Tower, the Community Orchard, and Meadowfield Drive all serve as these points within our plan.

The Walk The idea of taking in and giving out is present in the masterplan scheme. As we take in materials, ideas, and people from the area, each project has a purpose which benefits the village. Material recycling, shelter, education, and produce are all at the crux of the masterplan. With the main projects spreading across the edge of Duddingston, a cyclical path is formed, a pilgrimmage. Small interventions are featured along the paths to tie the project’s further together. The Foraging School lies at the top of the masterplan, tucked away in the wild and sitting away from the urban sphere. Trails and desire lines are present in the site, tying in the notions of gathering and pilgrimmage.

12
The Core The projects in the masterplan help to define the core of Duddingston. When visiting the village, it became clear that the historic core was detached from the gentrified expansion of modern constructions and commercial hubs. The role of the masterplan is to mark the edges and to honour the original core whilst allowing the wild to bleed into it.

Paths most travelled| Desire Lines Whilst visiting the site, I noticed that there were an abundance of trodden paths around the area, forming directions and routes. Desire lines are defined as paths of erosion and consequence from human activity. Interpreteted as places of gathering, the paths form are as important as roads, or official routes. They are products of human fascintation and curiousity.

Following the path | Foraging With recent social and environmental pressure for local produce, the activity of foraging comes to mind. In Edinburgh, there are a plethora of foragable material which are mostly edible or used for arts and crafts. Wild garlic, few flowered leek, and blackberries are wild produce whereas hawthornden apple and willow are cultivated in the community gardens in Duddingston.
25
Heading out | Topos
26
Context | Located at the edge of Duddingston, the site is located within the existing community orchard and willow nursery. Willows and apple trees are placed in a linear pattern around the site, juxtaposing the wild trees enclosing the field. Based in the transition space between the wild and the urban village core, the development will act as a device to connect the two. The closest buildings are quite low rise, around 1 - 3 storeys high. A path will be added to connect the Foraging School to the neighbouring development, as well as outdoor rooms which visitors must pass through, Slope | The site has quite a steep slope, roughly a gradient of 13.9%. The poses issues with accessibility and even ground. The site must be excavated to be suitable for construction. Wind | The prevailing wind in Edinburgh is from the North-East, and will be highly prevalent in such an exposed site. The outdoor rooms formed in my design will therefore require wind breakers to block visitors from the elements.
27
Discovering The Willows The call for sustainable and local produce has not been a new one, yet the importance remains the same. The nearby willow nursery offers an opportunity to utilise the communities resources and giving something back. An important reference has been The Basket Willow by William F Hubbard. Written in 1909, the bulletin shines a light on the traditional process available for willow cultivation and crafts

Discovering The Apples Upon realising the potential of the community orchard, Real Cidermaking on a small scale by Michael Pooley and John Lomax offered an indepth explanation of the plethora of opportunities and produce that an apple can have. This has undoubtedly influened the direction of my project and the progamme within.

Accessibility | As mentioned before, the sloping site poses issues of accesibility. A solution to this is to add a road and path into the development, allowing for accessible access and fire engine access. The road/path will also form a link to the neighbouring site. Both the public and private cores feature lifts that span the entire building, allowing wheelchair users to easily access the structure. Programme | The project is a school which will encourage the practice of foraging local produce such as berries, apples, and willow. These three organic materials are the focus of the proposal, where the programme is produced out of activities surrounding them. For berries, jam making workshops will be available, as well as a shop to sell the product. The nearby orchard offers an abundance of apples which will be used in activities such as apple butter making, and producing cider. The willow nursery also offers the chance to learn how to weave the material into baskets, as well as seasonal activities such as wreath making. The project will also contain a public cafe in which visitors can stay and see the view. On the ground floor, due to the steep slope, a stepping landscape will be produced to create an outdoor room whcih will inhabit a series of picnic tables and benches for other visitors that wish to stay outside.

Excavation | To accomodate the specific conditions required for willow storage, apple storage, and fermentation rooms, a basement will be included in the scheme due to its thermal mass qualities. Therefore, an excavation of the site will be needed. Structure | The general structure is comprised of primary and secondary timber beams and columns which feed back into the two central concrete cores. The primary and secondary timber beams will be exposed on each level to achieve a barn-like aesthetic. Blending in | An issue with having such an open site is that there might be some difficulty in the building looking out of place. To assist with this, the brick-clad cores will help link it back to the village architecture as well as the neighbouring development. Another issue is the materiality of the path linking the two projects. To help transition the manmade path into potentitally new desire lines and surrounding landscape is the introduction of green paths. Materiality | Approaching the site, the materials brick and timber are prevalent through remnants of past constructions and the brick path. To honour this, the building will be constructed out of a brick base and brick-clad cores and larch timber panelling as you rise through the building, Woven willow will be used as railing throughout the structure.

The school is located at the edge of the wild and the Duddingston core, whilst also being close to the freshwater Loch. Bookended by nature, the project seeks to blend in with the surroundings and to become a transition point between the wild and the urban spheres. 51
Woven baskets and cider The Foraging School is a culimnation of materials found around the site and the concept of gathering, hunting, and finding local produce. Offering a place of shelter, education, and leisure, the building sinks into the ground with a stepped landscape scheme with nature embedded throughout the design.

Planting To advocate the concept of the school blending into the surrounding environment, a cohesive landscaping strategy has been developed to ensure this. A sloped mixed media path joins the base of the landscaping to the top of the scheme, allowing both humans and cars to travel on it. An alternate route is formed by a series of vegetated stepped platforms, carrying visitors up to the school. The lower platforms will have additional apple trees planted in the same linear manner as the original format, allowing the community orchard to bleed into the newly formed landscape. To carry on with this stepped green-land, the building will also feature green spaces on different levels, allowing nature to intertwine with every lvel of the structure.

60
An opportunity for community growth Whilst the stepped platforms provide a route to the Foraging School, the smaller green areas on the other side of the sloped path offer a purpose which combines public and private life. With the project’s close proximity to the new housing development featured in the masterplan, the two green spaces provide allotment areas for community gardens or private plots for the residents.
61
62
The landscape hugs the existing ground by following the direction of the contours rather than going against it.

A home for apples and willow The existing willow nursery and community orchard currently offers no shelter from the elements. As it is such an exposed site, it seemed natural to propose a scheme which focused on the produce, yet offered a form of shelter and a place for education surrounding these things. The Foraging School aims to host workshops and classes centralling the apples and willows, creating apple butter, cider, woven baskets, and furniture.

The Roots The basement is comprised of concrete walls which are embedded into the earth. Using the earth to act as a thermal mass, the rooms on this level have specific conditions such as the cold storage room for apples, and warm heated rooms for general use and the fermentation rooms. One of the two cores roots itself into this level, whilst also providing access to the rest of the building.

Roof Plan The roof changes with what programme lies underneath. The extensive glazing is used to allow in an abundance of sunlight into the cafe/bar to produce a warm atmosphere within the space. Rooflights are also used in the corridor for the admin section to ensure sufficient lighting. Green roofs have been implemented to increase biodiversity within the area and to continue with the language used in the landscaping.

Structural Plan The structure is used as a construction tool and as a conceptual one. The timber columns which span the buildings add to the tree-like notion of the structure. To increase the tree-like atmosphere, the primary and secondary beams are exposed, mirroring branches. The two concrete cores act as the main structural support of the building, spanning two primary beams between them. All other structure returns back to these points. The cores themselves are concrete towers which also aid with the tree analogy, as the main structural support would be the trunk, and such are the cores.
101
102
The Branches The secondary structure is needed to transfer loads to the primary structure.
103
104
The Trunk The most essential part of the structure are the two concrete cores. All of the structure links back to the cores. Circulation and services are placed within these spaces. To mimick the notion of the two towers being tree trunks, the cores are both clad in brick to exert a heavy aesthetic.

The Outside, Inside A part of blending in with the environment is to bring it into the scheme. A significant portion of the building is sheltered outdoor spaces, allowing a transitional space to flourish. The building becomes a space where the outside and inside merge through the journey of ascending the slope and looking down. Thus, the initial journey of the approach has been expanded.

Materiality The architecture located near the site has been mimicked in the design by having larch cladding and terracotta brick. Separated by the central circulation space, the programme within is clearly defined from the outside. Activity spaces and general areas are clad in timber, inside and out, reflecting a warm interior and a warm space. The brick represent the functional spaces such as secondary circulation and services. Not requiring the same amount of comfort as the other spaces, the brick is also clad inside and out.

The main entrance to the upper levels brings you to the first floor, where a secondary staircase wraps around the void of the building and ascends you even further. The elevators enable accessible access throughout the structure, whilst also providing an efficient route to the storage basement,

Environmental Strategy To suit the programme, the building features a series of conditioned rooms. To efficiently store the apples after harvesting, cold rooms are required to ensure optimum quality. These are located in the basement where the thermal conditions are more consistent, using the earth as a thermal mass and a concrete structure. There are also warm rooms needed for fermentation and general thermal comfort throughout the building. These will be heated through underfloor screed heating. In the central circulation area, there are sheltered exterior spaces which offer efficient cross ventilation and air circualation on all levels. The cafe/bar on the highest level features an extensive openable skylight system which also aids with the cross ventilation and air circulation. The skylight also assists with efficient solar gain. Green roofs are implemented within the design which helps to regulate the interior temperature of the building, and encourages biodiversity in the area.

Northern glazing has been prioritised in the cooking rooms to allow constant light exposure to avoid glare.
To enable maximum passive heating and light into the structure, the glazing has been strategically placed to optimise the sun exposure.
Ground Floor
The form has allowed the formation of wind-free zones, creating outdoor sheltered spaces, such as the central walkway, and the area between the two northern extrusions. The added trees also act as windbreakers in the landscape.

Precedent Study
School in Orsonnens Nestled in the Swiss countryside is the GrangEcole, the Barn School. Inspired by local traditional farm barn forms, the school mimicks the structural focus and integrity of these shelters. A timber construction, the building expresses its structure with honesty yet refined. The clarity of the hierarchy between structure and interior is made evident as the shape itself molds the school’s programme.

The plans revolve around a central atrium which is used as a place of gathering within the school. All rooms fold around this central space, creating classrooms at the corners. The general arrangement of the rooms are carried through each floor. In the middle of the plan, a timber column comprised of four parts span the entire height of the building, spreading out as it ascends into branches to meet the skylight.
