Accessible via the Bouvets footbridge, Basalte is a decisive development in the renewal of La Défense, scheduled for 2016. Like the Exaltis building in 2006, the 160m long building is part of a revaluation and optimisation of land resources. It spans, between the Granite Tower and the Pacific footbridge, one of the main access routes to the circular boulevard.
Designed to accommodate 3,500 Société Générale traders, the building has five open-plan office floors, two technical levels and seven levels of underground parking.
From a technical point of view, the metal structures are "dry" mounted, ideal for narrow spaces, and consist of lattice girders to free up space on the floors. On the south side, these beams rest on a metal mesh that strongly marks the presence of the building.
Work on this building, designed by the architect Jean Mas (Ateliers 234), began on 21 July 2008. The construction of this structure is a technical feat due to its location, suspended above the RN 314.
A High Environmental Quality (HQE) approach was initiated as part of its construction.
Together with the Chassagne, Alicante and Granite towers, this building forms a 245,000 sq.m. property complex, with a workforce of approximately 16,000 people.
A word about the architect
Ateliers 234 was created in 2005 from the merger of the Bolze and Rodriguez-Pagès, Arene Et Edeikins and Mas et Roux agencies. With more than a hundred employees, this new agency has established itself as one of the leading agencies on the Parisian scene. Specialising in the search for environmental quality, Ateliers 234 also specialises in urban planning and landscape design under the name of Faubourg 234.
In 2009, they notably delivered one of the two office buildings that mark the Porte des Lilas in Paris, the other being designed by Valode and Pistre. The agency, which is relatively young in its structure but has had active employees since the 1980s, signed the Basalte building in La Défense.
