Descriptif Descriptif

The new world headquarters of JTI stands on the former industrial site of Sécheron, a changing district, comprising buildings of all periods and geometries. The form of this building strongly stands out in this place and its characteristic silhouette can be seen from afar. The complex volume is as if folded onto itself and terminates on two sides by impressive overhangs. The centre of this sculptural edifice defines a courtyard which brings natural light into the heart of the building. The entrance to the large entrance hall, which spans the building and is open to several floors, is located on rue Kazem-Radjavi. The plans for the administrative floors are all slightly different, since dependant on the specific contour of the predefined built form. However, they show great typological rationality by the precise layout of staircase, lift and service cores at the centre of open space office floors. The structure is entirely in steel and it is just as much a work of art as an administrative building. During the works, large hydraulic jacks supported the immense metal diagonal pieces while all the components were connected to create a beam effect. Apart from the building “heads” and the interior of the courtyard, the façade are executed according to the principle of a double skin in glass, the last layer consisting of large glazed panels, cut diagonally.
