The Trinity Tower is the first "IGH-Bridge" in France. The project, which will be delivered in 2020, is a technical achievement: the building complex spans the seven lanes of traffic on the Avenue de la Division Leclerc, including the access ramp to the La Défense tunnel (A14). In addition to creating new public spaces and modernising the intersection, it provides a new connection to the slab.

Thanks to its off-centre core, which offsets the lifts onto the façade in complete transparency, it interacts with its environment, and reveals its activity through the bioclimatic and kinetic façades which optimise the contribution of light and the terraces which punctuate the floors with trees planted in the open ground. Trinity has the will to place the architecture of the building at the service of these new modes of work: completely decompartmentalized spaces, terraces planted with trees and loggias, hybrid spaces, restaurants, rooftop business center...

The tower is certified to international environmental standards: double HQE "Exceptional" and BREEAM "Excellent" certification.

Today, a dozen companies, with a variety of activities, benefit from the tower's state-of-the-art services: Sopra Steria (consulting firm), Afflelou (optics), Technip (energy engineering and construction), Welkin & Meraki (coworking spaces), Altitude (networks), Santarelli (consulting firm), Viatris (pharmaceutical industry), etc.

A word about the architect

Cro&Co Architecture is an agency founded by Jean-Luc Crochon. The agency was chosen to lead this project because it places the well-being of the user at the heart of its thinking.

Having won several awards in the field (Trophées de la construction 2021, CTBUH Awards 2022 and 2001, Trophées Eiffel 2020, Prix Siati 2020, Prix Acier 2010, Prix AMO 2002), Jean-Luc Crochon stands out in the business district landscape.

Cro&Co has numerous office, housing and public facility projects to its credit. In Paris La Défense, the agency has a portfolio of technical and structural projects for the area:

  • Restructuring of the CNIT (2010)
  • Heavy restructuring of the Carré Michelet (2019)
  • Creation of the interfaces of the Éole station through the CNIT (delivery soon)
  • Reconstruction of the Odyssey tower (in project), with a group of international architects such as Jeanne Gang.
