This social housing complex, between urban social housing and greenhouses with lettuce for all, is a project by French studio Tétrarc Architects, in Nantes, France. Tétrac has created 39 social housing shapes as 11 “Houses” gathered side by side, creating a continuous volume.
The volume was designed to describe from its axis a light 21 degrees in flexion, creating two distinct households. Level by level, the first entity, in every level, has 6 rental houses, the second one is dedicated to the 5 sold houses.

In order to optimize the space for living rooms without increasing reference surface areas each housing is organized around a nucleus made of a kitchen, a bathroom, toilets, and a staircase for duplex apartments. For the same purpose, accesses to the housings are located outside the building as an unexpected & playful iconic element.
The volume with its 21 degrees of shifted forwards and backwards, their stepped placement creates a varied rhythm within the elevation. Every dwelling has a greenhouse in front of its façade. They are the continuum of the spaces inside the housing, provide more surface areas, and even are a great living volume in the duplexes. The block is defined on this site by a gridded glass facade offering unobstructed views of the garden plot adjacent to the building.
Finally, private gardens take place at the foot of each household, extending them and offering an innovative way to practice gardening in order to promote neighbourhood relationships.
Thus, Tétrarc plays different tunes. It sets the project in the modern history of individual social housing which began in 1920-1930. On the other hand, it provides an innovative answer to the sustainable social housing question with new forms and use of materials. It also provides a recalled quality of life to its inhabitants with its innovative performances of indoor spaces extended on the outside.

Nantes TETRARC
TETRARC, founded in 1988 in Nantes, discusses the architecture of very large: town planning, public spaces, new construction, industrial design, scenography and museum. Its four members (Michel Bertreux, Alain Boeffard, Claude Jolly and Jean Pierre Macé) are followers of the idea of total art and consider architecture as a poetic meaning. Appropriating the city in a fun way, the group develops buildings systematically seek to transform events into multifaceted complexity of programs and places. Its aim is to stimulate a new perspective on the city and strengthen its appropriation by expressive interventions, printing as second nature to the urban morphology.
TETRARC uses a vocabulary organic to break the orthogonality of the City and affix the personal brand of the group.
