The Burj Khalifa, previously known as Burj Dubai, (Arabic: برج خليفة, "Khalifa Tower") is the tallest tower in the world, spanning 168 stories and 2,684 feet high. Construction started on 15th April 2005 (6th Rabbi al-Awwal 1426), in Dubai, United Arab Emirates, at . It opened to the public on 4th January 2010 (18th Muharram 1431). The lead architect is Adrian Smith of the Chicago office of Skidmore, Owings and Merrill. The final height including spires, was not initially declared so that competing skyscrapers would not know of its height.
 Height Controversy
The speculation as to the final height of the Burj Dubai has ranged from 808 meters to over 1000m or even twice the height of the current tallest tower the tapai 101 building. For example a recent article by building subcontractor Persian Gulf Extrusions and dated September 20, 2006, stated that the final height would reach "over 940 metres" or at least 3084 feet.

 Comparison with Other Skyscrapers
At their convention in Chicago, the Council on Tall Buildings and Urban Habitat (CTBUH) defined four categories in which the world's tallest building can be measured:
- Height to the structural or architectural top (including spires and pinnacles, but not antennas, masts or flagpoles)
- Height to the highest occupied floor
- Height to the top of the roof
- Height to the top of antenna
In addition the current height of the worlds tallest structure is the CN Tower in Toronto Canada.
Upon completion the Burj Dubai in Dubai is expected to be the tallest building in all categories, as well as the tallest free standing structure knocking the CN Tower of the spot it has held since 1976 CE (1395 AH)
 The Design
The tower is composed of three elements arranged around a central core. As the tower rises from the flat desert base, setbacks occur at each element in an upward spiraling pattern, decreasing the mass of the tower as it reaches toward the sky. At the top, the central core emerges and is sculpted to form a finishing spire. A Y-shaped floor plan maximizes views of the Persian Gulf.
