The World's Tallest Building

The Burj Khalifa (formerly known as the Burj Dubai) officially opened last week, and measures in at some 828 metres over 160 floors!

20 Hindmarsh Square in Adelaide, which has also just been completed, is approximately 45 metres high. So even if you stacked 18 of them together, the resulting structure still wouldn't be as high as the colossal building in Dubai.

The Burj Khalifa sits as the centrepoint in an 11 hectare garden and contains over 1,000 apartments, a 160 suite hotel, 37 floors of offices and a 4 level club. The apartments were sold off the plan and apparently you can buy one now at 50% less than the price at the height of Dubai's property boom in 2007!
