The Chicago Spire was a supertall skyscraper project that was planned for completion in Chicago, Illinois, United States. Designed by Spanish architect Santiago Calatrava and developed by Shelbourne Development Group, the residential tower was intended to be the tallest building in the Western Hemisphere at an estimated height of 2,000 feet (610 meters) with 150 floors.
Overview The design featured a distinctive twisting shape, resembling a drill bit or a spiraling shell, which would have made each floor plate slightly rotated from the one below it. This unique aesthetic was a hallmark of Calatrava's work, known for its organic and sculptural qualities. The Spire was planned to house luxury condominiums, offering panoramic views of Lake Michigan and the Chicago skyline.
History and Development
- Initial Announcement: The project was first publicly announced in 2005 as "Fordham Spire," conceived by Christopher T. Carley of Fordham Company. The initial design was similar but slightly shorter.
- Shelbourne Development Acquisition: In 2006, Irish developer Garrett Kelleher's Shelbourne Development Group acquired the project, rebranding it as the Chicago Spire and increasing its proposed height to 2,000 feet.
- Construction Commencement: Site preparation and foundation work began in August 2007. A large coffer dam was constructed to facilitate excavation for the building's core.
- Financial Difficulties and Stoppage: Construction on the project was halted in 2008 due following the global financial crisis. Shelbourne Development struggled to secure additional financing, despite initial sales of condominium units.
- Cancellation: After years of legal battles, financing attempts, and missed deadlines, the project was officially canceled. In 2014, the development site was foreclosed upon, and later acquired by Related Midwest in 2014. The excavated pit, known as "Kelleher's Hole," remained a prominent feature on the Chicago lakefront for several years.
Site and Legacy The original site, located at 400 North Lake Shore Drive, remained vacant for many years after the project's collapse, becoming a symbol of the ambitious yet ultimately unrealized vision. In 2016, Related Midwest announced a new two-tower development for the site, which broke ground in 2018 and is now known as One Chicago Square.
Despite never being built, the Chicago Spire remains a notable example of ambitious skyscraper design and a significant chapter in Chicago's architectural history, embodying both visionary aspirations and the economic realities that can shape urban development.
