In Nanterre, at the western extremity of the district of La Défense, this project fits into an exiguous triangular site and figures as the prow of the Valmy district. Unique and autonomous, the triangular tower unifies the Société Générale’s block, optimizing the open spaces and preserving the light and sights in the existing towers.

“The project was designed as a major feature of the La Défense site. It forms a tall and slender triangular prism, like the prow marking the start of the Valmy sector.

The project occupies a triangular site and takes a dual form: a diahedral that forms the front of the complex, and prism-shaped flanks alongside the Alicante and Chassagne towers.

These forms combine the specific internal requirements of the project with the need to provide a strong external identity. The aim is to provide office space of optimum quality that brings together functionality, flexibility, atmosphere and comfort, while contributing a major landmark to the site that draws the area together.

The shape of the tower thus conveys a dual image: that of an independent building on the La Défense skyline, and that of a building linked to the two existing towers.
The pinnacle of the tower and the sloping roof accentuate its height, reinforcing the strong presence that stems from the building’s prime location in the landscape of La Défense and Nanterre. It acts as a focal point to pull together and add the finishing touch to the Valmy sector. This ability to draw the eye is accentuated by the tapering skyline, which is unique in the area.”
