Dubai Creek Tower, Dubai, UAE
If the latest reports are to be believed, the sensational Dubai Creek Tower will stretch up to a stomach-churning 4,413 feet into the sky. Set for completion in 2020, the $1 billion observation tower will be anchored to the ground with giant cables. When completed, the hypertall tower will boast 210 floors but only 54 of them will be usable. These levels will contain observation decks, SKY GARDENS, residences and a hotel, and the tower will also have TV, radio and communications antennae. One thing's for sure, the views from the top will be absolutely breathtaking.
