Commissioned to Claude Parent by the Societé Immobilière des Grands Magasins d'Approvisionnement Général (S.A.I.G.M.A.G.), this complex comprises one major store and related commercial spaces (6 300 m²), forty-two additional commercial spaces (1 980 m²), a car servicing center (600 m²) and a gas station (1 080 m²). Raw concrete, sloping roofs and detached façades unify the dual program, which groups small shops and one major supermarket. Here, the architect created a landscape, as he had started doing with his individual houses (Soultrait, 1956-1958; Drusch, 1963-1963; Bordeaux-le-Pecq, 1963-1965). He offered a new relief to observers, for whom the structure seems to emerge from the site: “The utilization of raw concrete highlights the implicit movement of the architecture. In this case, it is defined as a giant arrow at the entrance, like a zoomorphic form emerging from the underground car park” (C. Parent). Originally surrounded by fields under cultivation or lying fallow, it is easy to imagine how this mineral architecture functioned as a signal. The interior circulation paths enabling communication between the shops are composed of ramps with an 8% incline, following the precepts of the Oblique Function, which he had theorized with Paul Virilio between 1963 and 1968. Three slopes, expressed on the façade, represented a real innovation in this type of program in which functionality and clarity were of primary importance. The building was registered on the Supplementary Inventory of Historical Monuments in 2011.
