Location
The site occupies an exceptional position on the edge of Toulouse, borderedto the north and east by green space. Situated on former agricultural land, the immediate surroundings remain undeveloped. In line with plans for urban development, the new buildings herald the look of the whole neighbourhood, particularly in terms of their alignment and their relationship with the landscaping of the Touch river banks.
Arrangement
The project comprises 35 semi-collective housing units with basement parking. The units are divided into two groups of buildings, positioned along a central pedestrian path. Orientated east/west, their heights vary from Ground Floor +1 to Ground Floor +3. The indented forms were defined by assembling the different unit typologies - 1-bedroom to 3-bedroom. The buildings are alined with the new street to the north, opening up free space on the three other sides of the site.
Access
The main entrance is on the road on the north side of the site, passing under a building through to the central pathway accessing the different buildings. A second pedestrian entrance on the south side provides access to the area shared between the three developments via the vegetable garden/orchard area at the far southern extremity of the site. The apartments are accessed via the voids between the buildings. This system of distribution creates semi-private access, serving a maximum of two apartments per floor. The spaces between the built volumes allow in natural light and provide visual openings over the surrounding landscape. The access provided to the individual homes and that leading down to the basement constitutes a circulation system that is on a domestic scale.
Communal spaces
The shared communal spaces (path, vegetable garden/orchard) are catalysts for social interaction. The atmosphere created by the proximity and proportions of the buildings and their simple functionality are contributing factors to conviviality and community spirit.
Typologies
The arrangement of the buildings means that all the apartments are at least double-aspect, encouraging natural ventilation. The 1- and 2-bedroom apartments are mainly orientated east/west; the 3-bedroom duplexes, classic or inverted, are triple-aspect, predominantly opening to the south. All apartments have some form of outdoor space:
— 35 to 170m2 gardens for the ground floor apartments.
— 11 to 60m2 terraces or loggias for the upper floor apartments.
These private outdoor spaces encourage appropriation of the apartments. Designed as real extra rooms, they ensure privacy in order to encourage use.
Facades
The facades follow the building method established at the very beginning of the project for the ideas competition. The separating walls are finished in pale render, the facades clad in finely veined, powder-coated anthracite-coloured steel sheets. This alternance of materials according to the orientation of the facades gives an identity to the project and breaks down the volumes to ensure that they blend into the surroundings. The play of open/closed 'accordeon' shutters adds to the animation of the facades, particularly on the path side.
Semi-collective housing
This project is the result of an ideas competition launched by Oppidea in March 2013. Semi-collective housing is at the heart of current urban preoccupations (quality for users, controled density and economical use of land). The response chooses to orientate itself towards a flexible system rather than a rigid fixed proposition. It is a question of developing a system with both constants and variables. This process makes it possible to reply to the diversity of contexts, densities and programme arrangement.
The system
The system revolves around different constants:
— The grid
— The building system
— The housing typologies
— Means of access
— Designated use of communal spaces
— Generous private space
Standardisation
This approach encourages reflection on the standardisation of a system with multiple applications. The proposal constitutes a well-founded response to the economic constraints while ensuring the building quality. A system structured around constants cannot fulfil all the needs specific to a project. The system must also incorporate variables that enable adaptation to different needs:
— The arrangement by typology
— The facades
— The relationship to the ground plane
— Parking requirements
