Saudi Arabia Starts Work on World's Tallest Building

The 200-floor tower will be located in Jeddah overlooking the beautiful Red Sea. It will house the five-star Four Seasons hotel, luxury apartments, office spaces and on the 157th floor, a massive 98-foot terrace. The cost is expected to be $1.23 billion and will require 80,000 tons of steel and 5.7 million square feet of concrete which must be able to withstand both salty seawater and strong winds. It will take approximately five years to complete.

The Kingdom Tower is the first phase of Jeddah Economic Company's approximately $20 billion, 17 million-square-foot Kingdom City project, of which it will be the focal point.
