Amazingly, another of London's Olympics stadiums has actually been completed on time, with the basketball stadium becoming the fourth to be finished off. Designed to be temporary, the building will be recycled after the 2012 London Olympics.

Measuring 35m high and made from 1,000 tons of steel, it's not known what the stadium will be recycled into. It could be shipped off to the next country lucky enough to be elected the Olympics host, paving the way for less affluent countries to have the privilege, but I can't help but think with that puffy white exterior, it could house a marshmallow factory. Or become the Stay Puft man's new abode. [London2012 and BBC via Architizer via Inhabitat]
