The project offers a variety of housing typologies, and each house'design allows for the spatial expansion that is easily adaptable to family development. The internal organisation of the dwellings deal on a thick wall. This wall has a structural, structuring and ecological function at the same time. It combines three devices: Storing the sun's heat energy for the night, through the roof glazing; Bringing fresh air through the walls to temper it and diffuse it into the main rooms; Containing the chimney ducts to make maximum use of the heat from the wood fire. The quality of the available envelope will also be optimal from a technical, thermal and architectural point of view. Residents will be able to choose between a wood or metal facade. The orientations are the best, both in terms of solar gain and comfort and in terms of views. The ridge of the houses is equipped with solar panels for the production of domestic hot water, facing south.
At the heart of the site, the walls do not separate the houses; on the contrary, they unite them, symbolising the collective spirit. These walls, built-in brick, define a singular landscape. They also serve as a wind barrier thanks to their curved ends. From the sky, the houses seem to form pearl necklaces. They are distinguished by the variety of sizes and by the diversity of the facings. Parallel to the walls, the service roads run along the northern facades. Their location at the foot of the slope makes the cars invisible to the inhabitants of the upper terrace. By using these "camouflaged" access roads, the view escapes through a succession of holes in the wall, revealing the wooded horizon. The walls extend into the groves. Stairs offer the opportunity to climb up the crest of the widened walls, which have transformed into veritable perched terraces. The site is newly wooded and slightly reshaped in its lower part to accommodate a phyto-treatment and water retention basin.
