The “world`s largest building” has opened in southwest China .
The towering 100-metre (330-foot) high New Century Global Centre, which is said to be big enough to hold 20 Sydney Opera Houses, opened its doors Chengdu on June 28.
The complex, which Chinese officials say is the world`s largest standalone structure, is 500 metres long by 400 metres wide, offering 1.7 million square metres of floor space.
The New Century project is a sign that China’s growth has spread from the country’s more prosperous eastern and southern regions to the west, where wages are lower and the central government has encouraged development with subsidies and tax breaks.
With its booming economy, China has become home to some of the largest and tallest buildings in the world.
