The project is located to the south of the Grand Ensemble de Sarcelles-Lochères (the first major French development built by Jacques-Henri Labourdette and Roger Boileau between 1954 and 1976), at the crossroads of the old town to the east and the ZAC des Poètes to the west. This site is at the heart of a territory born of modern thought, a starting point for reflection. Faced with these abstract architectures, with thin, smooth façades and no spatiality, the building proposes a different relationship to the exterior, where the surface of the façade becomes thicker until it becomes a place. For each dwelling, a private loge/courtyard is proposed as an entrance space, offering additional exterior surfaces protected from view. This device gives the architecture a strong identity, based on a constructive realism where the assembly of raw materials seems both rustic and precise.
