Burj Dubai, which will be the world’s tallest building, now has more floors than any other building in the world.

It is currently only just over half its final height but is already one of the world’s five tallest buildings, at 422.5 metres. Its 120 floors are more than any other building. The final details are being kept secret, but rumours are that it will be around 800 metres and over 200 storeys when complete.

It will be the tallest building in the world in all four categories recognised by the Council on Tall Buildings & Urban Habitat, which ranks buildings on the basis of spire height, the highest occupied floor, roof height and pinnacle height.

The tower forms the central feature of a vast new city being built, at a cost of US$20 billion, around an extension of Dubai Creek, which has been doubled in length.

Burj Dubai was designed by Skidmore, Owings & Merrill, who are Chicago-based, and is being constructed by South Korea’s high-rise experts Samsung Corp. Turner Construction International is the project and construction manager.
