The decision to construct the building is based on the government's decision to diversify from an oil-based economy, and for Dubai to gain international recognition. It is designed to be the centrepiece of large-scale, mixed-use development. The building was opened in 2010 as part of a new development called Downtown Dubai.

The primary structure is reinforced concrete and some of the structural steel for the building originated from the Palace of the Republic in East Berlin, the former East German parliament. Ĭonstruction of the Burj Khalifa began in 2004, with the exterior completed five years later in 2009. With a total height of 829.8 m (2,722 ft, just over half a mile) and a roof height (excluding antenna, but including a 244 m spire ) of 828 m (2,717 ft), the Burj Khalifa has been the tallest structure and building in the world since its topping out in 2009, supplanting Taipei 101, the previous holder of that status.
