Social Housing in Mulhouse

This project for 14 single-family houses is part of an operation for 61 dwellings created by five teams of architects* in the extended space of a housing estate in Mulhouse.
Our aim is to produce quality houses that are, for the same price, considerably larger than the standardized housing usually met with.
To begin with, the creating of a structure and a cheap and effective simple envelope enables us to define, on the loft principle, a maximum surface area and volume with contrasting, complementary and surprising spatial qualities.
On the ground floor a post/beam structure in concrete supports a platform at a height of 3 m, upon which horticultural greenhouses are fixed. The frame is in galvanized steel, the walls in transparent polycarbonate. Part of the greenhouse is isolated and heated. The other part constitutes a winter gardne, largely ventilated via the roof and facade. A horizontal sunshade unfurls inside the greenhouse.
The greenhouse principle, with its automated climate-control devices, has enabled solutions to the bioclimate to be developed.
Later on, we divide the volume into 14 dwellings**, set crosswise in duplex form, which profit from all the different qualities offered by the diversity of the spaces.
