The design, created by American architect Adrian Smith, who also designed Burj Khalifa, incorporates many unique structural and aesthetic features. The creator and leader of the project is Saudi Arabian Prince Al-Waleed bin Talal, the wealthiest man in the Middle East, and nephew of the late King Abdullah.
The multivariate form of the tower is rationalized by a “Y”-shaped plan and a continuously smooth taper, which will significantly reduce structural loads by obviating the need for the complicated outrigger transfers and belt trusses required in a setback approach.
A public viewing deck could be located at around 800 meters from the base of the tower, which is roughly near the height of the current World's Tallest Building, Dubai's 828 meter Burj Khalifa.
There are plenty of technical challenges involved with building a one-kilometer-high tower, including (but in no way limited to!) lackluster elevator tech and the sheer weight of a tower this tall. And we haven't heard about Kingdom in months, which seemed to indicate that the economic demand just wasn't there.
The Jeddah Economic Company (JEC) has signed a deal with Alinma Investment for more funding to enable the construction of the Kingdom Tower in Jeddah. Thus, a 2.23 billion USD fund has been established by the Kingdom Holding named Alinma Jeddah Economic City Fund.
Work has already begun up to the 26th floor of the tower, located in Obhur, just north of Jeddah, on the Red Sea coast, but the finished building will have almost 200 floors.
While the design is contextual to Saudi Arabia, it also represents an evolution and a refinement of an architectural continuum of skyscraper design. The three-petal footprint is ideal for residential units, and the tapering wings produce an aerodynamic shape that helps reduce structural loading due to wind vortex shedding.
