- UNIT BRIEF When the architectural avant-garde dissipated forty years ago, its project of rectifying society by creating a continuum of building and city also came to a close. The endgame of the avant-garde took the form of urban-scale architecture. Our unit returns to this moment in order to examine the possibilities of affecting society today via urban-scale architecture. ‘Scale’ is considered as a tectonic issue with significant implications for city and society. By developing architectural designs which are not limited to ‘site’ in the conventional sense, the intention is to produce through architectural project a critique of the subordination of architecture to the discredited contemporary urban, economic, and societal conditions. In order to articulate such a critique, the unit emphasises the relation of the singular building to the urban multiplicity, and particularly architectural form to urban morphology. Such emphasis, accompanied by a thorough consideration of public programmes as well as of the traces and scars created by political-economy in the built environment, will be the key factor in the unit’s ambition to identify the architectural role in future societal transformation.

SITE ANALYSIS Tracing an Urban Identity Broughton, once a separate entity from the city, has a history of industry and production. Tram and rail lines ran through the area, serving the light industry that developed in Broughton’s northern periphery.
Over time, the expansion of Edinburgh’s city centre and the Port of Leith upon Broughton’s ambiguous boundaries has caused its identity of production to fade. Belonging to different powers and controls yet resistant to be absorbed into any, the political, social and economic disjoint is reflected in its varied urban fabric. The single industrial rail line that remains from Broughton’s past cuts through the urban fabric as a nostalgic reminder of the area’s history and a physical representation of its current divided character. Potentiating these necessary infrastructures of industry and production may reactivate Broughton’s lost identity.
A LINEAR GROWTH An Urban Pattern The case study of the re-introduction of the tram to Edinburgh reveals a linear growth potential. The tram proposal has an influence on its adjacent urban fabric. Developments to fall within staggered zonings are to contribute to the trams construction to varying degree. The method for assessing the amount of contribution is based on the degree of accessibility to the proposed tram system. The policies reveal the power of infrastructure connections on an urban scale and the linear growth they initiate.

To make use of the existing industrial line that intersects with Leith Walk - overlaying a main strip and transversal strips.
Building upon the lasting fragments of Broughton’s industry.

Reinventing the waste industry as an opportunity to activate the area and Broughton’s production identity. Adding cultural value to an infrastructure currently considered with zero value. Interaction of public with waste industry, material production and cultural consumption.
MOMENT 2 PROPOSAL
The project references a time when Broughton was more engaged with the industries and mechanical infrastructures that supported it. Currently the city and Broughton neglect to interact with these infrastructures, leaving them as forgotten parts. We identified the industrial waste rail passing through the site as a physical fracture to be mended and reactivated through our scheme.
The scheme proposes a new street within Broughton, located on its existing industrial railway line. The rail line’s existing programme sets up the timetable of our proposal: the train leaves the Powderhall Destructor, Edinburgh’s single waste compaction site, at 10am with the city’s compacted waste in containers out to Dunbar landfill and returns empty at 2.30pm.
The scheme consists of a housing , material recycling and arts programme that occupies and connects with the industrial rail line and its waste industry. The linear activation of a new industrial street cutting through the centre of Broughton engages the area by day, through production and exchange, and by night through public interaction and the arts.
The scheme works in a four-way collaboration between the industrial, the residential, the urban and the artistic community. The Powderhall destructor takes on a new role of sorting Edinburgh’s scrap materials for reuse, providing the materials for the scheme.

LANDSCAPED SITE PLAN OF SCHEME
The timetabled mechanical operations of the Powderhall site continue down the tracks to six different â€˜stationsâ€™ at which the waste train mechanically exchanges its scrap material to be further processed at each stop. The housing units are forged around each station and directly dispose of their waste via them rather than through the complex networks of waste distribution throughout the city.

The scheme works on multiple time scales: 10:00 - 11:45 Scheme The scheme adopts the train’s existing timetable and proposes additional stops at different points along its route to Dunbar landfill. As it stops, exchange stations and their housing units become activated. 9:00am - 4pm Scheme Daytime activity – Exchange stations, workshops and studios are privately active. Workshops refine the scrap materials for studio cladding and for exchange with the city. Studios use scrap supplies in the creation of art. Waste of zero-value is processed to materials of the highest cultural-value. 4pm- 9am Scheme Night-time activation - Public activation of new street. Via access points extended from Broughton’s existing road networks, the public filters through the tracks to inhabit the landscaped street and access the open studios from the new street.
Yearly Scheme The whole scheme will be constructed over an extended period of time, as materials are gathered and processed for the cladding of the studio spaces. Studio spaces are ‘inserted’ into the housing units and multiply down the scheme over years. As material starts to degrade, cladding is simply replaced. The scheme enables the gradual deconstruction of the waste material, the reassembly of its parts into new forms, and the distribution of these. Resisting the typical urbanising of a site, the scheme speaks of productivity, industry and mechanics.

Materials are exchanged between stations via the trash train. They are distributed on a city scale via a public level to each exchange station, according to the scheme’s timetable. The scrap is refined in stages in each of the stations’ workshops along the scheme. Produced is cladding for the studios and further processed materials to exchange with the city. Studios creatively use the scrap supplies in various degrees of refinement in the creation of art. The waste pivot on the residential level to each exchange station allows residents to directly dispose of their waste via the scheme. Engaging the resident with the waste industry they rely on - the residents are not fully conditioned by the industry, but may be informed by it.

MOMENT 5 HOUSING UNITS & ARTIST’S STUDIOS The housing units mediate the urban with the industrial use of the site - through mechanical shutters facing the tracks the resident engages with the trash train through a ‘mechanical shield’ and filter it into their urban lives.
With the artists working closely with the scrap materials to produce art from trash, their studios open up after-hours for the public to access via the new street, transforming the evening landscape into one of culture and building upon Broughton’s image as an area of production.
