The dynamics of the Nantes metropolitan area in favor of participatory housing has led to the emergence of a large number of land parcels in the various ZACs (urban development zones). The increase in the number and scale of participatory projects has forced all the professional players involved to strategize around this way of making the city and housing.
Housing is an essential spatial and social landmark, and the way it is lived in is an expression of individual psychology. Our view of the world is often intimately bound up with the places where we live. Consequently, the design of a housing project, from the layout of the site to the placement of the furniture, is not a matter of applying a recipe, but rather a quest for quality of life.
In the context of technical specifications and demanding standards, participatory housing projects offer living spaces that are not simply lived in. When it comes down to it, what a family really wants is a little extra soul, an atmosphere that makes them feel at home. Contrary to what one might think, the challenge is less technological than human.
The group of residents was supported by CIF Coopératif, with the help of Ômesweetôm and Echohabitants, from the moment the project management team was chosen. Claas architectes, a firm familiar with participatory housing projects, played a full part in the development and running of the workshops, from the ground plan to the layout of each individual dwelling.
Each scale of the building thus features a series of shareable devices, spaces and techniques. Wherever possible, the creation of common areas encourages cooperation and mutual aid, and fosters neighborly relationships. We have been careful to ensure that the notion of privacy is always respected, and that relationships can be woven in progressive concentric circles (next-door neighbor, stairwell, building, condominium, neighborhood).
The result is a multiplicity of paths made visible by the exterior staircases. They give a feeling of individual access to one's home, while always being close to and in contact with one's neighbors.
Common and shared spaces are located on the diagonal linking the garden to the Vergers du Launay neighborhood. They act as a gateway to the project, and can be used to host events that are open to the neighborhood, or more intimate, focused on the garden. In a participatory project, the architecture provides a framework that residents can appropriate for their own development. This appropriation becomes the synthesis of the building's generosity and the group's expression of living together.
The project highlights the design and construction of wood-frame collective housing, with only the first floor of the collective built of masonry to contain the parking lot. The timber structure has made it possible, simply and economically, to arrange the dwellings in tiers on the garden side. This arrangement allows for the creation of large private terraces and contributes to the interior ambience of the dwellings, with visible solid wood ceilings.
While the architectural expression of the project remains simple, the design of the timber structure has allowed for a play of steps and recesses in the facades. The result is a free-flowing volumetric interplay, with a succession of different facade planes from every vantage point.
This formal freedom is counterbalanced by a regular rhythm of facades and openings. This modenature regulates the scale of the building and the openings that are inserted into it. Only the spandrels vary, reflecting the living style of each dwelling.
