274 apartments grouped around two interior courtyards, laid out in separate 7-storey buildings with distinct characteristics: L'Amphithéâtre and Les Colonnes. The ground floor of the two buildings is occupied by shops, and has an underground car park for 300 cars. L'Amphithéâtre was designed as subsidized housing, and Les Colonnes as apartments to be sold on the open market. The geometry of the apartments is based on a combination of modules. The basic module is 65 m2, equivalent to a three-bedroom apartment. All of the houses have dual orientation. The interior façade of the houses which delimit the elliptical plaza takes the form of a curtain wall, with a rhythmic sequence of glass columns which makes it possible to provide every apartment with a glazed window bay. Some of the apartments are laid out over two levels, and have an interior balcony opposite the curtain wall.
