Tallest Super Structures of the Future
Chicago Spire, designed by architect Santiago Calatrava, will become America’s tallest building by the end of 2010, raising higher than the Sears Tower and and the new Freedom Tower in New York, at 609 m (2000 feet).
The shape of this structure is the one really impressing, looking like a spiral that screws itself into the sky. The Chicago Spire will be built on the piece of land (280 square miles) from the junction of Lake Michigan and the Chicago River. The current plans call for the bottom 20 floors to be occupied by a hotel, while the rest of the building is filled with 1200 luxury condominiums. Construction began this month and the colossus is scheduled to be completed by late 2010.
