The Tallest Building in North America

So what if its development recently changed hands? Chicago's in store for an humongous tower, a huge twisting mass of metal designed by Spanish architect Santiago Calatrava, that will sit right on the lake. Only the Burj Tower, under construction in Dubai, will be taller. Reaching 2,000 feet at its spire, the 124-storey building will house a five star hotel and 300 luxury condominiums, ranging in price from $600,000 to $5 million. It's scheduled for completion in 2010. Via NYT
