With the headquarters in Saint-Denis coming to the end of the lease, it was time for GRT GAZ to set up a new head office in a new building under construction. GRT Gaz RICE is also getting closer to its other sites. This new headquarters represents a major challenge in terms of image and attracting and retaining talent, and is a showcase for the company. The management behind this ambitious project wishes to change and develop working methods to encourage transversality and exchanges.

  • Decline GRTGaz's DNA by offering them a "smart" working environment that serves their activities 
  • Create spaces called "territories" that are friendly, warm, bright and stimulating
  • Development of many meeting spaces calibrated according to usage: bubbles, meeting rooms, village square.
  • Accompaniment on the workplace throughout the project: permanent communication and exchanges with the client who moves from a closed office environment to dynamic open spaces
