Orange Headquarters - Issy-les-Moulineaux

Design & Build

Our Build teams have supported the world leader in telecommunications in the fitting out of its first global headquarters, in an emblematic building designed by Viguier, on the banks of the Seine in Issy-les-Moulineaux.

This is the first time in the history of the group that Orange will have its global headquarters in France.

Our historical customer asked us in June 2020 for support on the execution part of the project. The objective of this support was to carry out the Build project, that is to say to support the realization of all the arrangements as a general contractor.

Through this project, the team had to demonstrate its capacity for adaptation, agility and responsiveness, of course facing the pandemic, but also the shortages of materials and the various logistical phenomena that resulted from it.

“The image of this project is really... the bridge: we have been able to create a bridge between the past and the future of the Group.“

Emmanuel Lagrange, Directeur projets immobiliers, Orange
