Tétrarc has created 39 social housing shapes as 11 “Houses” gathered side by side. The resultant continuous volume describes a light 21 degrees inflexion on its half, creating two distinct households. As the first one contains 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. In the same purpose, accesses to the housings are located outside the building as an unexpected & playful iconic element.
