London Olympic Stadium 2012
Contrasting with the enormity of the "Bird's Nest" Beijing Games, the Olympic Stadium in London is simple in design. At a cost of 486 million pounds (720 million francs), it was designed as a modular structure so that they can be reused after the Games. Its upper floor, made of steel and concrete houses and 55 000 temporary seats can be dismantled in order to reduce the total capacity of 80 000 to 25 000 seats.
