Kingdom Center is a 41-storey, 302.3 m skyscraper in Riyadh, Saudi Arabia. It is the third tallest skyscraper in the country after the Abraj Al Bait Towers and the Burj Rafal, and is the world’s third tallest building with a hole after the Shanghai World Financial Center and Tuntex Sky Tower.
Besides the shopping mall, Kingdom Tower contains the Four Seasons Hotel Riyadh and apartments. There is a 56 m sky bridge atop the skyscraper.
The building is situated on 100,000 square metres site with car parking for 3,000 vehicles.
The upper third of the tower features an inverted parabolic arch. The building utilities butt jointed glazing combined with the lack of both distinguished floor lines and other tall buildings around it. The lower two thirds were constructed with a reinforced concrete frame while the top third has a tubular steel frame.
The architectural model maker of the Center was Richard Tenguerian.
- The inverted arch at the top was described by the developer as the city’s “necklace”, because the opening is lined with aluminum to highlight the unique shape in contrast all of the facade in reflective blue glass.
- The main lobby is a elliptical space with ribbed vaulting, elevated walkways, a fountain, and rows of palm trees. This elliptical form is a footprint used overall in the building objects and decoration.
- The Kingdom Center has won an important award in 2002 for its design.
- The original design called for a tower of 296.3 meters, but it was later increased.
