Jeddah Kingdom Tower vs World's tallest buildings

Jeddah Tower (Arabic: برج جدة‎),[11] previously known as Kingdom Tower (برج المملكة) and Mile-High Tower (برج الميل), is a skyscraper under construction in Jeddah, Saudi Arabia, at a preliminary cost of SR4.6 billion (US$1.23 billion).[12] If completed in 2020 as planned, the Jeddah Tower will reach an unprecedented height, becoming the tallest building in the world as well as the first structure to reach the one-kilometre-high mark.
It is the centerpiece and the first phase of an SR75 billion (US$20 billion)[13] proposed development known as Jeddah Economic City that will be located along the Red Sea on the north side of Jeddah. The development of Jeddah Tower seeks to bring great changes in terms of development and tourism to the city of Jeddah,[14] which is considered the most liberal city in Saudi Arabia
