The world’s tallest building is the Burj Khalifa in Dubai, it rises 2,722 feet above the city and was the building featured in Mission Impossible 4, when Tom Cruise swung from it. It will be short lived as the world’s tallest though as 7 of the 10 tallest are being built in China.

When completed, the world’s tallest building will be in Saudi Arabia, the Kingdom Tower. It will stand 3,280.84 feet and will cost $1.23 billion. It is nicknamed the mile high tower, but it is just a little shy of a mile. A mile is 5,280 feet. The building was originally planned to stand 5,250 feet but the geography of the area proved to be unstable for a building at that height.

The completion date of the Kingdom Tower is expected to be in 2018.
