Trapèze Joint Development Zone

An inhabited neighborhood in place of the Renault factories.

Le Trapèze is a vast seventy-four hectare urban development project located in Boulogne Billancourt along one of the meanders of the Seine. The area covers all the former Renault factory sites, which ceased operations in 1992. Urbanization began in the early 2000s and is now complete.

The particularity of the sector’s urban grid is based on the creation of Macro-Lots, whose size and scale make it possible to create a programmatic mix within the same block: facilities, housing, offices, etc. It was in this context that the Brenac & Gonzalez & Associés team was appointed to define Macro-Lot MLB4, its interior micro-urbanity and to coordinate all the architects involved in the planned programs. Koz architectes was responsible for a retirement home, Sarrebrück and Hutton for an office program, and Brenac & Gonzalez & Associés for two housing projects and a chapel.

The unity of the whole is given by the central garden, structured by the continuity of a light-colored concrete floor with a curved, irregular layout that sometimes approaches, sometimes moves away from the facades.

This mineral carpet-like floor frays, sometimes tearing, to make way for mounds of earth where large massed plantings or beautiful trees take their place.
