La Liberté consists of two residential towers. One is eighty meters high, the other one is forty meters. They are built on a glass platform.
The highest tower consists of two building volumes, slightly shifted from one another. The towers are connected by means of a pedestrian bridge. Both towers have space for 120 three bedroom apartments.
As the complex is near to the highway, Perrault has designed the apartments as soundproof as possible. The windows of the apartments are fully closed and only serve for the passage of light.
Perrault created an illusion of'open windows' by placing mirror glass panels. These panels reflect the daylight and keeps the sound off.
The apartments are built on a glass platform that serves as office space. The residential towers and the premises are separated by a covered terrace. Perrault also designed the two gardens and the underground parking.
