While Frank Lloyd Wright’s mile high skyscraper exists only on paper, Chicago architects Adrian Smith and Gordon Gill have been commissioned to design a kilometer high skyscraper for real in Jeddah, Saudi Arabia, which will be the world’s tallest building. The Kingdom Tower aims to be a new landmark for the city, providing a focal point for its new waterfront district that the firm also is master planning.
The math is tricky: The 1,000 meter building will rise with 163 occupied floors reaching about 650 meters, with an additional 100 meters set aside for a possible pendulum mass dampener (to prevent the building from swaying), and the remaining 250 meters will be all spire. Housing office space on 300,000 square feet of the lower floors, the tower continues with seven floors of hotel rooms, more than 100 floors of residential units, and two sky lobbies. The 125th and 126th floors will feature an observation deck, while the 157th floor will boast a projecting sky terrace for the “super penthouses” at the very top levels.
