Known as Kingdom Tower this will be the world's tallest skyscraper will be 3,300 ft. and 170-stories. The building is currently under construction in Jedda Saudi Arabia, at 26-floors. When completed in 2018 the structure will supplant the Burj Khalifa (2722 ft), as the tallest building in the world. Adrian Smith and Gordon Gill Architecture, a Chicago-based firm, created the design for the Kingdom Tower.
Of course this will all be dwarfed if the previous posting for a mega-tall tower is funded and ever moves beyond the stage of proposal.
We've been tracking this building for a while before construction began. It has been interesting the varying height and design proposals along the way.
That's over 1k.
