U Arena

Research project: the U Arena of Paris La Défense (92)

For the competition to design the future U Arena in La Défense, the studio designed a box–building, for music and for sport. The stadium is covered by a glass lid that ensures absolute acoustic and climatic impermeability, opaque in the roof and gradually becoming transparent as it moves down to the ground. Its facade opens like a drawer to welcome spectators into a world of spectacle, closing behind them to protect local residents from the noise. On match days the roof opens right up to allow for open-air tournaments. An office tower, a requirement of the brief for this mixed development, sits on one edge of the stadium and completes a powerful attachment to the site in its soaring form, bringing the sky to its occupants.

Programme: rugby stadium for 32,000 spectators, concert hall for 40,000 spectators, offices, restaurant, shops, car park | Area: 35 000 m² offices | Client: Ovalto | Architect: Cro&Co Architecture | Facade: Arcora |Acoustic: Peutz | Economy: AE75 | Completion: concours sur invitation 2010 | Address: La Défense, Nanterre (92)
