The museum space of the Villa du Temps Retrouvé in Cabourg occupies 2,624 square feet (800 m²) of the former Bon Abri villa built by the Parents, a family of architects and friends of Marcel Proust. The house now consists of three main buildings organized around a central courtyard. The main building of stylized Norman architecture built in the 1860s to the south is completed to the north and west by concrete and brick extensions added a century later. The roof of the Villa du Temps Retrouvé is covered with slate.
