132 E Delaware – Bloomingdale’s
900 North Michigan in Chicago was completed in 1989. At 871 feet, it is currently the seventh tallest building in Chicago and the 25th tallest in the United States. It was developed by Urban Retail Properties in 1988 as an upscale sister to Water Tower Place, one block southeast, and was the second vertical mall built along the Magnificent Mile.
The building features a large, upscale shopping mall called 900 North Michigan Shops. Bloomingdale’s occupies the rear of its wide, six-story atrium, with other luxury shops and restaurants filling the remaining spaces. For this reason, it is commonly referred to as the “Bloomingdale’s Building”.Offices originally occupied floors 8-28, but floors 21-28 were converted to condo units in 2007, leaving offices on floors 8-20. The luxurious Four Seasons Hotel occupies the middle floors (32-46) of the tower. Floors 48-66 are part of the 132 East Delaware Residences, these 106 condominiums were part of the original building plan.
The exterior of the tower is clad in limestone and green glass which reflects the light. The building has a steel skeleton on which a concrete frame was erected for the upper floors. Because the building materials changed, cranes used to work on the lower floors could not be used for the concrete portion and new cranes had to be erected to complete the building.
