The Silex 2 Tower is situated in the Part-Dieu district of Lyon. The project involves the rehabilitation of the existing EDF tower and an extension to it with a new 22 storey tower. The superstructure culminates at a height of 122m and offers an exploitable surface area of 30 000m². The two towers are linked by an 8 storey base building housing shared services. Parking levels are contained within the infrastructure.

The project is developed by two agencies Ma Architectes and Arte Charpentier.
