French studio Explorations Architecture have completed a sports hall in Tours, France, with a curving timber roof that sags in the middle.
The entire north facade of the Monconseil Sports Hall is glazed to maximise natural light, while timber batons shade the south facade from direct sunlight.
The suspended roof spans the 50 metre-wide hall, which can seat up to 700 spectators.
The building provides a venue for sports that include basketball, handball, volleyball and gymnastics.
Back in 2008, Explorations Architecture designed an entrance-pavilion for the Chateau de Versailles - see the story here.
Other public sports halls on Dezeen include one near Sydney with a steel shell exterior and another in California supported by exposed fir trusses - click here to see more stories relating to sports.
