Chicago Spire @ foundation

Chicago's buildings are known for innovative and revolutionary designs. The Chicago Spire will complement this pattern, and standing at 2,000 feet (610 m), will further transform the already changing Chicago skyline. Crane parts and construction equipment arrived at the site on June 25, 2007. The following day Shelbourne Development officially announced the first construction contract.

Plans for the tower include 1,193 condominiums with each of the building's 150 stories rotating exactly 2.44 degrees from the one below for a total 360 degree rotation. For supplemental structural support, each floor would be surrounded by cantilevered corners and four concave sides. Similar to the Sears Tower and John Hancock Center skydecks, the Chicago Spire will house a community room at the top floor offering residents a view of four states. The soaring four story lobby of the skyscraper will have translucent glass walls and be framed by arching, steel reinforced concrete vaults. The building has been labeled as a giant "drill bit" by the public and others in the media have likened it to a "tall twisting tree" and a "blade of grass".
