The land, located in the PPRL zone, required that the main rooms were located above the altitude of Xynthia +60cm, which resulted in the installation of a large crawl space to raise the floor by half a level. As the garage could be on the ground floor level, it was therefore decided to organize the floors in half levels covered by monopitch roofs. On the garden side, a terrace on stilts prolongs the stay on the outside.
