This stadium has a capacity of 20.000 covered seats, and stands in the inner city (in the middle of a park), as it is replacing the former Charles Berty stadium. This
stadium is multipurpose-capable: football, rugby as well as events. Supported by a metallic frame, the transparent and round shapes of the roof have been built with wood purlins and glass. It minimizes the visual impact of the building and smoothes its integration in the urban landscape.

Thanks to an inner technical ring and an outer architectural one, all the functional units are laid under the stands.  Included in the design is the possible extension of 10.000 more covered seats. It will be feasible, with the addition of a balcony. The stadium includes a 1000 places buried parking lot which allows preserving the external planted area.

Designed per High Environmental Quality standards, the stadium benefits special treatment regarding sound quality and noise protection, and features environmentally selected building products including 1000 m² photovoltaic roof panels. Finally, this project includes specific urban facilities such as service roads and the extension of the C tramway line.

The project includes a total floor area of 85,400 m², of which 26,500 m² are in superstructure and 58,900 m² in infrastructure and a car park of 550 places.

The structure required 34,400 m3 of concrete, 12,200 m² of masonry and 3,200 t of metal framework. The structure of the museum consists of two sloping ceilings and mezzanine floors of about 40 m wide and 250 m long, supported by bi-articulated metal “stilts”. The stability of both blocks of the museum is ensured by the concrete cores placed at the ends and the central metal pears. A 20 cm central expansion joint allows maximum non-throttled movement in case of emergency.

The roof of the museum, housing the restaurant and the library, consists of a deactivated concrete slab, accessible, of 10.000m² near the Seine and the Eiffel Tower.

The structure is protected against water ingress from the basement by a perimeter diaphragm wall with a maximum height of 30 m, recessed at its base in the sands of Bracheux and through a plastic clay layer thus forming a waterproof cap. All around, a clay merlon integrated into the landscape as well as the perimeter walls provide protection against a hundred-year flood of the Seine (with a security guard of 30cm).

A large 80,000 seat Stadium built in Saint-Denis Paris area. A large metallic cablestayed structure weighing 8,500 t. with 65 m. long cantilevers covers a 62,000 m² surface 10,000 m² of which are made of glass.

The city of Lille launched in 2007 a stadium project which would match the UEFA demands and which could also host various cultural and sports events.

Structure engineering of special structure: roofing, sliding roof.
