On 3 October 2012, Jean-François Sammarcelli, Deputy Chief Executive Officer of Société Générale, Philippe Perret, Chairman and CEO of Sogecap, Henri du Boucher, Chairman and CEO of Sogeprom and François Bertière, Chairman and CEO of Bouygues Immobilier laid the foundation stone of Tour D² in the presence of Joëlle Ceccaldi-Raynaud, Mayor of Puteaux and Chair of EPADESA, Didier Montchamp, Secretary-General of Hauts-de-Seine prefecture, Eric Césari, a local councillor from Courbevoie responsible for monitoring infrastructure projects in La Défense and surrounding areas, and Philippe Chaix, Managing Director of EPADESA.
Tour D² stands on the current site of the former Bureau Veritas building and was designed by architects Anthony Béchu and Tom Sheehan. D² will be the first high-rise in La Défense with a steel exostructure and will stand out in the business district's skyline thanks to its rounded shape and external steel grid. Rising 171 m above the ground, it will accommodate 4,000 people on 36 storeys over a floor area of 54,000 m².
This resolutely innovative high-rise has been designed to optimise space, as shown by its TWIN® lifts. This system, which is also a first in France, allows two independent cars to travel in the same hoistway, thus reducing the size of the building's core and freeing up room for more office space. There will also be a roof terrace garden on the 37th floor.
In order to maximise user comfort, Tour D² will seek High Environmental Quality certification. It aims to obtain six very high performance and four high performance grades. The focus will be on energy efficiency with an objective of consuming at least 30% less energy than the highest HQE® performance level.
Located on a gently sloping pedestrian route, the high-rise will have a bar & restaurant of around 400 m² open to the public and directly accessible from the new main road currently being developed by EPADESA to replace the current ring-road. This intelligent urban design makes D² a strong link between the Municipality of Courbevoie and La Défense.
For this project, Sogecap is the investor and Sogeprom and Bouygues Immobilier are the joint property developers. It forms part of the La Défense renovation programme, which aims to build around 150,000 m² of new space via demolition-construction as well as extension operations. Handover is scheduled for the end of 2014.
