That is praise indeed. These architectural awards are only bestowed on winners after a lengthy consultation exercise – carried out in conjunction with the magazine Muuuz – involving a large group of architects and designers. More than 26,000 votes were cast to select the most remarkable achievements of the year. Thus, this is a genuine endorsement from the entire profession.
Admittedly, there are plenty of reasons why Tour D2, designed by Anthony Béchu and Tom Sheehan, should appeal. Its rounded form and steel exostructure, with its grid-like appearance, give the building a unique silhouette amongst other buildings in La Défense. Tour D2 forms part of La Défense's renewal plan.
Innovation is the hallmark of the entire building. It is the first tower in France to be fitted with the TWIN lift system, which uses two independent cars, thus reducing the area of the service core and providing more usable floor space, which totals 54,000 m². Additionally, because the most advanced technology in ecological construction has been used, Tour D2 can boast first-rate environmental performances, having received HQE and Breeam certifications along with the BBC low-energy RT2015 (thermal regulations) label and notice of compliance with RT2012 (thermal regulations).
The icing on the cake of this building is its astonishing open-air gardens, situated at an altitude of more than 170 m.
