Opened on the Seine and the slopes of Sèvres and Meudon, the Trapèze, at the heart of the major development project Ile Seguin - Rives de Seine, on the bank of Billancourt, develops as a "city park" invested by a particularly rich biodiversity. The architectural and environmental ambition, the balance between free and social housing, offices, green spaces, shops and public facilities, close to the island Seguin and its ambitious cultural vocation, contribute to creating an exceptional place of life in the immediate west of Paris.
