In July 2007, EPAD launched an international call for projects for the construction of the Tour Signal, which forms an integral part of the plan for Tour Signal, La Défense, Paris, France. Due for completion in 2015, the Tour Signal will symbolise the renewal of La Défense. The winner is Ateliers Jean Nouvel. The team has chosen to locate its project at the Porte Ouest to open up the La Défense neighbourhood to Puteaux.
The project comprises 71 storeys, forming a mixed-use building which brings together apartments, hotels, offices and retail premises in the lower section. It is made up of four blocks piled one on top of the other with atriums forming huge windows, each facing in alternate directions. These perspectives reveal floor levels which form balconies within each of the atriums.
