The project, located in Boulogne-Billancourt in the Parisian suburbs, involves a building with eight social housing units, a caretaker’s lodge, and a shop on the ground floor.

It is driven by a desire for restraint in design and the use of natural, bio-sourced, and local materials without ever losing sight of comfort for the occupants.

The structure will be built out of wood on a foundation of stone. The goal is to create a decarbonized building without concrete.

Designed as a place of meeting and relaxation, the green roof is accessible to all including a terrace and a vegetable garden. In fact, each inhabitant will have their own vegetable plot.

Composting facilities will be available on the roof to minimize collective waste and create quality soil for plant growth.

The façade at street level will be made of raw earth blocks, thus following the precepts of the “cradle to cradle” concept based on two principles: zero pollution and 100% reusability. The soil will be retrieved locally from the «Grand Paris» Metro borehole excavations.
