Structure in General
- The slender twisting structure resembles a narwhal's horn.
- Each floor is rotated about two degrees from the one below, forming a tapered tower which twists 270° from the base to the roof.
- According to the architect, the tower's shape was derived by imagining the plume of smoke from a campfire lit centuries ago by Native Americans at the mouth of the Chicago River.
- Construction officially started in 2007, but was abruptly halted in 2008 in the midst of the Great Recession.
- As of February 2014, an investor is planning to invest $135 million to fund the reorganization of the building's finances, which would allow the construction of the tower to proceed.
- If completed, Chicago Spire will be the tallest building in the United States and the Western Hemisphere.
- This building will have the longest elevator run in the world.
- Chicago Spire's lot is situated by the mouth of the Chicago River, and also guards the entrance to Ogden Slip, a short branch of the river to the north.
- This is the third serious proposal in Chicago for an extremely narrow tapering skyscraper that would surpass the Willis Tower in height; the earlier proposals were the Miglin-Beitler Skyneedle and 7 South Dearborn.
