This project is located in Saint-Didier-au-Mont-d'Or near Lyon. The house made of black rough concrete provides a large setting on nature. The long glass front opens onto a patio with exceptional views of the Monts du Lyonnais. Below, a pool forms a long, dark and mysterious swimming corridor. The purified volume of the house is embedded between two cubes of dry stone that bring a specific minerality to the project for which the outdoor living areas are very important. A spa and therapy supports the master bedroom.
