The hyperbolic paraboloid-shaped steel-framed structure sits on a 360 degree glazed concourse at entry level, and is clad in timber with little apertures to allow for natural ventilation.
The lightweight, double-curving, cable-net roof structure was designed to reflect the shape of the cycling track.
6,000 seats are located all the way around the track and are split into an upper and lower tier by the glazed concourse.
48,000 cubic metres of material was excavated to create the bowl in which the building sits.
The London 2012 Velodrome will host the Olympic and Paralympic indoor cycling events and also includes changing rooms, retail facilities, workshop and a viewing concourse.
