Since 2008, there has been a giant hole where Santiago Calatrava’s Chicago Spire was supposed to rise some 2,000 feet out of the ground. The project lapsed due to financial woes by Irish developer Garrett Kelleher. The foundation is in place, and it looks like a place where a giant swimming pool or music venue would fit nicely, but AN is hearing that developers are working with Bjarke Ingels’ Danish firm BIG on a possible Spire part to.
