Triangle de l’Echât mixed development area

The Triangle de l’Échat site is a one-of-the-kind urban entity, created by this network of motorway infrastructures. The main challenge of the project is reconverting an archipelago dominated by the road system to a real city district that is connected, habitable, porous, and accessible to all. It is based on a plan for reclaiming public spaces and developing a large number of housing units, built around local businesses and a school complex.
By keeping some of the already existing buildings, the project proposes the insertion of mixed macro-plots, organised according to a vertical planning hierarchy. A first section, designed as the base, contains flexible-use, traversable and modular spaces, set in the middle of a dense palette of vegetation and intended to be a counterbalancing natural space. The housing programmes are planned to rise above them and meet the requirement to provide generous and qualitative outdoor spaces. Finally, the progressively tapering roofs featuring terraced gardens outline a horizon widely open to the sky.
Known as “the islands of silence”, these plots will implement a harmonious structural transition from an eclectic urban environment to a peaceful island environment. Acoustic insulation will be provided by studying the allocation of development plans within the mixed islands, by using differentiated treatments of façades according to their exposure to noise.
