London 2012: Stadium design unveiled

The design for the main stadium for the 2012 London Olympic Games has been unveiled.

Following the games, the 80000 capacity venue will have 55000 seats removed, converting it to a smaller permanent sports facility.

The central 'bowl' of the stadium will be sunk below ground level to bring spectators close to the action.

A 28 m-span, cable supported roof will cover two thirds of the seated area, while a fabric curtain will wrap around the structure providing additional protection and shelter.

The stadium will be built by the Team McAlpine consortium, which is led by contractor Sir Robert McAlpine, and includes HOK Sport, Buro Happold, HED and Savills Hepher Dixon.
