Developer Unibail-Rodamco-Westfield (URW) has awarded Belgium contractor Besix the construction of the 180-metre-high Tour Triangle in Paris, designed by the architects Herzog & De Meuron.
The €670m mixed-use tower will be sited in the 15th arrondissement in the southwest of the city and will have 91,400 sq m of floor space distributed over 42 storeys. It will be third-tallest building in the French capital, behind the Tour Montparnasse and the Eiffel Tower.
The project has been delayed by a lengthy planning process and a number of legal challenges.
When complete in 2026, it will have offices, a conference centre, health centre, cultural centre, crèche, a hotel and a restaurant.
It has been designed to comply with the Breeam Excellent (minimum) and HQE Exceptional environmental certifications, as well as the Effinergie label. To achieve these standards the tower will have geothermal systems, a district heating network and energy and heat recovery systems, as well as a bioclimatic façade and 1,000 sq m of photovoltaic panels.
Planning, logistics and construction methods have been developed by Besix Engineering, the company’s in-house design office, to minimise the project’s local impact, including on the Parc des Expositions. Besix Engineering will also investigate how to support façade construction.
The project targets a minimum of 50% concrete with reduced CO2 emissions and recycled aluminium facades. The project will also offer 100,000 hours of social integration in partnership with the Ensemble Paris Emploi Compétences association.
URW’s project management team includes Setec and Egis, respectively in charge of the design studies for the structure and fluids, and Artelia as the execution project manager.
Besix said the project would would create 5,000 direct and indirect jobs.
