Adrian Smith + Gordon Gill Architecture
Adrian Smith, FAIA—who led design on the Burj Khalifa while still at
Skidmore, Owings & Merrill—is outdoing even himself with his scheme
for the Kingdom Tower in Jeddah, Saudi Arabia, which is slated to take
over as the world’s tallest building with an overall height of more than
1 kilometer (3,280 feet). To combat the wind forces that occur with any
building of this size—“the key to resisting wind forces in a tall
building is shedding vortices,” Smith says—the highly reflective glass
façade is continuously sloped, changing the dynamics at every floor and
shrinking each successive floor plate 4 to 8 inches. The tower is
supported by a central core, which is braced by 2-foot-thick concrete
walls that line the double-loaded corridors in each of the three wings
in the tripodal structure. The projected 5.7 million square feet of
floor space will be occupied by a stacked program of office, hotel, and
residential units, all serviced by a fleet of 59 elevators. A sky
terrace, 100 feet in diameter, is cantilevered off of the 157th floor,
roughly 2,000 feet in the air. First designed as a helipad—until “we
started talking to helicopter pilots and they said ‘it gets dicey up
there,’ ” Smith says—it will likely be used as a private terrace for a
penthouse unit. Construction is expected to begin on the foundations
soon, and the tower should be complete within the next five to six
years.
