UK-based architectural firm Foster + Partners has secured final approval for Hermitage Plaza, a mixed-use project in Paris, France.
The project will include two 320m towers that will house a hotel, spa, apartments, offices and serviced apartments, as well as shops at the base.
The development is part of a collaboration between Foster + Partners and the development agency for La Défense (EPAD), the City of Courbevoie, Atelier de Paysage Urbain and Departement de Hauts-de-Seine.
Foster + Partners senior partner Grant Brooker said: "Our ambition was to create a project that would inject new life into La Defense by bringing a new type of occupation and creating a new public focus on the edge of the Seine."
Built on an area of 161,458ft², the two buildings face one another at ground level and enclose a public piazza.
The first tower will have 86 floors and house a hotel, a business centre with a 250-seat auditorium, a spa centre, a fitness centre and apartments.
The second tower will have 85 floors to house office space, a 500-seat auditorium, a spa centre, a fitness centre and apartments.
The tower will be built over the broad base of four smaller buildings which will house office space, a shopping plaza, a concert hall and an art gallery.
Both towers will be built in a diamond-shape and turn outward to offer views across Paris.
The towers will have angular facade panels to promote self-shading and vents will be able to be opened to draw fresh air into the structures.
A crystal-shaped podium building will house office space with two detached satellite buildings housing a gallery and an auditorium.
The towers will be built in a diagrid structure, which will require less steel and emphasise the shape of the towers, according to Foster + Partners.
