Burj Khalifa is the world's tallest building

Burj Khalifa has surpassed Taipei 101 which was the world’s tallest building by 320 metres. Burj Khalifa with a height of 828.00 meters has been declared the world’s tallest building by the Chicago-based The Council on Tall Buildings and Urban Habitat (CTBUH). CTBUH has received and examined detailed drawings of the Burj Khalifa submitted by building owner Emaar, and can now confirm the official building height at 828.00 meters (2716.54 feet), as well as the title of ‘The World’s Tallest Building’.The Burj Khalifa has become the 16th building to hold the title of the “World’s Tallest” and stands an additional 773 meters higher, or 15 times taller, than the world’s first “tall building” (the Home Insurance Building completed in Chicago in 1885). The Burj Khalifa exemplifies four major trends in current tall building construction, with respect to location, function, structural material and height. The building also contains a record-breaking number of floors, at 163; a record previously held by New York’s World Trade Center Towers at 110 floors. The Burj Khalifa’s observation deck becomes the second highest in the world at 452.10 meters (1483.27 feet), surpassed only by that of the Shanghai World Financial Center at 474 meters (1555.12 feet).
