Photos: The biggest building in the world

The "New Century Global Centre" building (top) is seen standing among several buildings in Chengdu, in southwest China's Sichuan province on June 6, 2013. The center, claimed by Chinese officials as "the world's largest standalone structure", is going to be opened to the public on June 28. The 100m high "New Century Global Centre" is a symbol of the spread of China's boom: 500m long and 400m wide, with 1.7 million square metres of floor space - big enough to hold 20 Sydney Opera Houses, according to local authorities.

The New Century Global Centre, which is fairly Chinese, as building names go, is now, officials claim, the world's largest standalone structure. Another claim to fame? An "indoor seaside" pleasantly free of smog.
