From the beginning it was part of our architectural concept to create a building that complies with the French green building standards HQE. It was also the investor’s wish. And we succeeded. Thanks to our design of the exostructure and the choice of materials, steel and concrete, we were able to reduce material consumption by 30 percent. This is in comparison to other towers the same size. And as you know, less material also means less carbon emissions.
The building had to be very compact and the shape of the tower was rapidly defined to fit its surroundings. A rectangular shape would have been very difficult to fit within the cramped plot. Moreover, I wanted a soft and rounded shape around which that would fit into the dense context. I also knew opting for an exostructure skin would allow for better structural stability and reduce the section of the structure and core. One can then wonder about the open diamond shapes at its base.
KEY FIGURES
Plot area: 3 457 sqm
Surface area: 54 000 sqm net area
including 48 710 sqm usable surface
Height: 171m over 40 levels including 3 underground levels and a garden in the clouds
Number of floors: 37
Capacity: 4 200 people
Building materials:
5 500 T of steel for the structure and façade
3 000 T of beams for the tower’s exo-structure
12 000 m3 dof ready-to-use self-placing concrete
Glass
Each steel diamond shape span (over 6 floors) is composed of 2 x 14 ton-“V” assembled on site
