Clean Tower, Chicago, Hi-Rise Lo-Carb, Illinois Institute of Technology, Chicago Architecture Foundation

The Chicago River served as a dumping ground and an open-air sewer for much of the city’s history, and until recently, most downtown developments turned their backs to the river. The Clean Tower concept seeks to create a new relationship with the river by purifying water and creating water habitats. A “living machine” artificial wetland would be used to filter and purify the building’s wastewater, which would have the ability to clean more than 1 million gallons of river water per year, according to the team.

Some of the water that would be cleaned by the living machines would be used to fill large pools, which would be located between the building’s two wings, every eight floors. Private residences would also feature personal river wetland gardens.

Creating a leaning tower enables a developer to push the tower to the back of the property without sacrificing views. Under the Hi-Rise, Lo-Carb studio’s plan, the site would contain a large public plaza on the front of the property, extending from the banks of the river around the new building. A retail boardwalk and more wetlands would be located in the plaza, and it would also contain a large pool in the summer and an ice rink in the winter.

This plan is of course conceptual; the actual plan for Wolf Point is a $1 billion proposal that calls for three large (but not supertall) high-rises designed by Pelli Clarke Pelli Architects and Chicago firm Chicago firm bKL Architecture. So far, reactions to the proposal have been mixed. “The problems range from a traffic study that appears overly friendly to the developers who paid for it to building designs that are, at present, underdetailed and uninspired,” Chicago Tribune architecture critic Blair Kamin recently observed.
