Tour Triangle, also known as Projet Triangle, or simply Triangle, is a skyscraper to be built in the exhibition site Parc des Expositions de la Porte de Versailles in Paris, France. Designed by the Swiss agency Herzog & de Meuron, it will take the shape of a 180 metres (590 ft) tall glass pyramid with trapezoid base, wide from one side and narrow from another. It will be the only tall building built in central Paris since the 1973 Montparnasse tower.[1]


Tour Triangle will be a triangle-shaped building that culminates at 180 metres.[2]

The Swiss architectural agency Herzog & De Meuron, which had previously designed the 'Bird's Nest' Olympic stadium in Beijing, was chosen to design the project.[3]

In April 2011, VIPARIS,[4] the project owner, was given the green light for Triangle.[5][6] The tower site is located next to Porte de Versailles in the “Parc des Expositions” (southwest of Paris).

The plans for the construction of the tower were initially rejected by Paris City councillors on November 17, 2014. A second ballot on the matter by the Paris City Council on June 30, 2015 approved the building.[7] Critics of the Tour Triangle had opposed the project because of its controversial height. The 42-story project is to be the first skyscraper to be built in low-lying Paris in approximately 40 years since the construction of the Tour Montparnasse, the scale of the latter which still provokes animosity amongst Parisians.[8]


Being 42 floors high, it would accommodate about 5,000 employees and host offices, street-level shops, panoramic observatories and a panoramic restaurant on the top floor.[2]

Sustainability and environmental quality[edit]

Tour Triangle was to be a sustainable skyscraper: It was designed to achieve a high energy performance and reach the HQE and BREEAM certifications. It would favor natural light, and generate one-fourth the CO2 of a standard building of its size.[9]
