Burj Khalifa [Arab.,=Khalifa Tower], skyscraper in Dubai, United Arab Emirates, that is the tallest building in the world. The centerpiece of a large urban development, it stands 2,717 ft (828 m) high and has 160 floors. Designed by American architect Adrian Smith of the firm Skidmore, Owings and Merrill, the structure has a triple-lobed footprint derived from a native flower and becomes more slender as it rises to its spire by means of staggered setbacks. The exterior, clad in reflective glazing, with aluminum and textured stainless-steel spandrel panels and vertical stainless-steel fins, has patterns derived from Islamic architecture. Construction of the tower began in 2004 and was completed in 2009 known as Burj Dubai while under construction, it was renamed when it opened in 2010. A mixed-use building, the tower contains a luxury hotel, residential apartments, corporate offices, and suites.
