Tour Trinity, Office skyscraper in La Défense district, Puteaux, France
Tour Trinity is a modern office tower in the La Défense business district, rising 167 meters with 33 floors of workspace. Transparent elevators run along the exterior facade, allowing views across the Paris region as they move up and down the building.
The building was completed in 2020 and became the first tower of its kind to be built above a seven-lane road in France. This pioneering construction approach opened new possibilities for development in an already densely built area.
The tower's name comes from the 3,500 m² public plaza it creates, linking the CNIT and Coupole districts of La Défense above the Avenue de la Division-Leclerc. Landscape architect Bas Smets designed this planted deck, reached from street level by public stairs and lifts. Since 2021 it has housed the headquarters of Unibail-Rodamco-Westfield.
The tower sits above the Avenue de la Division-Leclerc, and a 3,500 m² landscaped plaza on its roof links the CNIT and Coupole districts of La Défense. Public stairs and lifts connect this esplanade to street level. The site is in Courbevoie, not Puteaux, so check the commune when planning a route.
The building features an off-center structural core rather than a traditional central core, allowing for more flexible interior layouts. Its construction used concrete formulated to produce significantly fewer carbon emissions during manufacturing.
