Kohn Pedersen Fox

This spiraling, supertall office tower in the heart of London's financial center has been under construction since 2008, but work is currently on hold. When complete, it will reach 941 feet and 64 stories. Overlapping rectangular glass panels on the exterior of the facade will give it a snakeskin appearance.
