The tightly packed business district of La Défense never seems to stop building upwards. The skyscraper cluster is constructed on a massive elevated concrete slab that hides integral transportation links below. But the district's height differential from the ground of the remainder of the city has created accessibility issues. Complex networks of stairs and elevators need to be installed in order to properly service and connect the busy neighbourhood. New developments, like Unibail Rodamco's Trinity, are building with these issues firmly in mind, as they develop ways to link their projects to the outlying streetscape.

The Crochon Brullmann + Associés-designed tower will rise from an extension of the existing concrete pad, stretching over Avenue de la Delegation Leclerc, which travels to the nearby city of Courbevoie. Access points to this new infrastructure will be provided by two flights of stairs and an elevator. Officials at a February 2016 community consultation stated that construction of the slab would take approximately a year and a half.

Recent photos by Forum contributor Vincent ! show steady progress at the site since the last full photo update in March. A substantial wall, serviced by a pair of tower cranes, has erupted and covered about half of the thoroughfare thus far. Besides the new tower, 3,500 square metres of new public spaces will supplement the development. The 32-storey building will contain about 49,500 square metres of office space and 500 square metres of retail.
