How many floors does the Burj Khalifa have?

The Burj Khalifa has 163 floors.

The Dubai skyscraper is commonly credited with 163 floors, making it the world’s tallest building and one of the most ambitious projects in modern architecture. Its official floor count includes 154 occupied or principal levels plus nine additional maintenance levels.

Construction began in 2004, the structure was topped out in 2009, and the building opened on 4 January 2010. It was designed by Skidmore, Owings & Merrill, with Adrian Smith as chief architect and Bill Baker as structural engineer. Its reinforced-concrete buttressed-core system helps support the extreme height.

A frequent source of confusion is that different counts refer to different things: the 163-floor total, the 154 main floors, and the 160th floor reached by the main staircase are not contradictory. The building also has two underground parking levels. Its architectural height is 828 meters, while the tip reaches 829.8 meters.
