The 180 meter high office tower serves as the focal point for the east of Paris in the new urban development of the XIII arrondissement. The tower consists of five city blocks of only six stories each, cantilevered from two vertical cores with open space between the volumes. Each block has an open inner court and vast roof gardens. In this way, a new type of green urban skyscraper has been developed that combines the quality of a low-rise urban fabric with the potential of high-rise tower. The foot of the tower has a hotel and shopping center, as well as ten underground parking levels.
