In the heart of Paris La Défense, Trinity is an avant-garde development that challenges the traditional codes of the office tower. Agile and lively thanks to its architecture open to the city, it innovates to inspire the talents of tomorrow. With its panoramic elevators on the facade, its terraces planted with trees, its rooftop business center, its connected services, its hybrid spaces designed as "augmented homes", Trinity frees the circulation of ideas and stimulates collective intelligence for a unique user experience. The result of a close collaboration with Paris La Défense, Unibail-Rodamco-Westfield and the local authorities of Puteaux and Courbevoie, the tower is an urban seam joining two slabs of La Défense with green and tree-lined connections. The project is a technical feat: the building complex spans the 7 lanes of traffic of the Avenue de la Division Leclerc, including the access ramp to the La Défense tunnel (A14). The motorway ramp has been transformed into an urban green space, thanks to innovative technical solutions found in partnership by Paris La Défense, Unibail-Rodamco-Westfield and the government services that manage the overhanging roadways (DiRIF).

To access this square, new staircases and elevators have been created to reinforce the existing link between the Serpentine intersection and La Défense, which notably allows for quality accessibility for people with reduced mobility.

The Trinity Tower also proposes a new architectural model. Thanks to its off-center core, which offsets the elevators on the facade in all transparency, it is in interaction with its environment, and reveals its activity through the bioclimatic and kinetic facades which optimize the contribution of the light and to the terraces which punctuate the floors with trees planted in full ground and suspended meeting rooms. Trinity has the will to place the architecture of the building in the service of these new modes of work: completely decompartmentalized spaces, masterly reception lobby, terraces planted with trees, hybrid spaces, restaurants, business center in rooftop...

The tower meets international environmental standards: double HQE "Exceptional" and BREEAM "Excellent" certifications. Today, a dozen or so companies, with a variety of activities, take advantage of 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 tower, a concentration of innovative services

Within the tower, a range of excellent, tailor-made services is offered:

  • the 25th floor and its panoramic view for the business center and the wellness area
  • hyperconnected collaboration spaces and personalized services adapted to all business configurations.

A brand new square at the foot of Trinity

Louise Pikovsky Square offers 3,500 square meters of new landscaped public space with 60 planted trees, at the foot of the Trinity Tower. Design furniture in wood and vegetation contrast harmoniously with the granite slab floor of the square. A shop, at the foot of the tower, will enliven the place. Trinity and its pedestrian spaces represent an urban seam linking spaces on the slab by embellishing them with vegetation and trees. Escalators and elevators have been installed to ensure pedestrian connections between the slab and the natural ground on the one hand, and between neighborhoods whose difference in level exceeds 5 meters on the other.

At the same time, Paris La Défense has carried out modernization work on the intersection of the covered lanes and their security. The arrival of the Trinity and Latitude real estate programs was the trigger for the requalification of the public spaces of the district to reduce their road character in favor of wider pedestrian spaces, enhanced with plantings and new furniture.

This space, below the stairs, was redesigned with the aim of marking the entrance to the business district, through a composition in the form of a large ellipse that can be read at ground level and from above and that unifies the different components of the intersection. Paris La Défense's achievements have made it possible to calm this intersection, by pacifying traffic, giving back their place to pedestrians and cyclists thanks to new crosswalks and the creation of a cycle path, while greening and levelling the alleyway alongside the Résidence Leclerc to facilitate travel for people with reduced mobility.

Lastly, the installation of new paving, furniture and quality lighting gives this area a more modern identity, like a square, in line with the developments carried out by the property developers. These new connections have now been delivered, facilitating travel between the CNIT, the cities and the Coupole-Regnault district.
