Speculation was rife as to what dizzy height the tower would ultimately reach.

According to officials at Nakheel, the tower was originally designed to be at least 700 m tall and have more than 160 floors, although an early render showed the tower with more than 200 floors.

Companies involved in the project reported an initial height expectation of 1,600 m, which was later reduced to 1,200 m. In July, 2007, Nakheel CEO Chris O’Donnell was reported to have said that “height isn’t everything” and suggested that Al Burj might not be any taller than the Burj Khalifa, which is 828 m. Yet only a week later, Nakheel reaffirmed that the tower would be taller than one kilometre and a report on June 20, 2008 claimed that the tower was planned to be 1,400 metres tall.

Ultimately though, they could have said it was going to be tall enough to reach the moon (363,104,000 metres if you are interested) as in January 2009, it was announced that the project was put on hold due to financial problems.
