Puteaux, France
The French architecture office Cro & Co has designed Trinity tower together with landscape architects Bureau Bas Smets and Phytoconseil, in the business district of Paris La Défense: a new 33-storey high rise building over 150 meters high with the exceptional feature that it is placed on a concrete slab suspended above a seven-lane highway.
The new150-meter Trinity tower enjoys an exceptional location in the business district of La Défense, in Paris, on a site that had to be invented. In order to ensure its successful insertion in this particularly dense built environment, surrounded by architectural icons (CNIT, Tour Areva, Tour Total), Trinity stands tall above the traffic routes.
In total, the new project for SCI Trinity Défense contains 56,000 m² of offices and 4,000 m² of services accommodate nearly 4,500 employees.
Trinity is the first tower in La Défense to develop an off-center core with a “heart of life” which moves the elevators behind a glass facade.
In this way, the activity of the building is revealed, the employees are visible from the outside and take advantage of the landscape of La Défense.
The green terraces and collective reflection areas are located near the elevators to become improvised meeting points.
To these common horizontal circulations (CHC) revisited are added a series of other informal spaces: the tower has a total of eight terraces decorated with trees in the ground, twelve green loggias and 23 balconies, or 1,500 m² of outdoor space.
At the top of the tower, six floors merge into three duplexes, the 25th floor has a panoramic terrace and the 33rd can accommodate a large meeting room.
Through this transparency and its very interactive aspect, the Trinity Tower displays in the district of La Défense its high technical, urban, architectural but also ecological ambitions because it is equipped with bioclimatic glass facades playing the role of external insulation and has the double certification HQE Exceptional and Breeam Excellent.
Trinity is at the same time a work of art, architecture and town planning.
Its concrete solutions help transform the former single-purpose business center of La Défense into a meshed city district: 3,500 m² of landscaped and public spaces will be created in its wake, linking the CNIT and Coupole-Régnault districts, so far disconnected.
