The Chicago Spire was a planned supertall skyscraper that began construction in Chicago, Illinois. The skyscraper would have stood taller than Chicago's Sears Tower and New York's upcoming Freedom Tower, as well as Toronto's CN Tower, thereby becoming North America's tallest free-standing structure and the world's tallest all-residential building. The building was designed by Spanish architect Santiago Calatrava and was being developed by Garrett Kelleher of Shelbourne Development Group, Inc. Originally announced in July of 2005 by Christopher T. Carley of the Fordham Company, the project was supported by many Chicagoans and city officials. After several months of development, Carley failed to acquire necessary financing and the project was taken over by Garrett Kelleher of the Shelbourne Development Group. Since that time, three major revisions were made to the design. After the initial construction began and then stopped, the project was eventually transferred to developer Related Midwest, which in 2014 announced the project would not be completed.
