One of several downtown supertall projects proposed in this cycle is losing supertall status thanks to a height reduction.

The Helmut Jahn-designed tower set for 1000 S Michigan Ave could be cut from its original proposed 1,001-foot height to 823 feet, well below the 984-foot minimum required for designation by the Council on Tall Buildings and Urban Habitat. The move is part of a deal brokered between the Emanuel Administration and the Landmarks Commission, Curbed reports. The site falls within the boundaries of the Historic Michigan Boulevard District, meaning Jahn's design must respect the size and scale of the existing buildings.

The developer is a JV of JK Equities and Times Equities, which also bought the Lightner Building at 1006 S Michigan in June. [Curbed]
