Not only is Helmut Jahn the architect behind a new tower planned for 1000 S. Michigan Avenue in the South Loop, but this new building is expected to stand at a whopping 86 stories — a height that would make this one of the tallest buildings in Chicago. Of course, the news comes literally just hours after a 76-story tower proposal designed by architect Rafael Viñoly made its public debut. According to drawings uncovered by the development watchers at Skyscraper Page, the tower would stand at a height of 1030', which would make it the fifth tallest tower in Chicago, or sixth if the 93-story Wanda Vista is completed before it. The tower would stand two hundred feet over the 76-story Viñoly-designed tower for 113 E. Roosevelt Road and would consist of 506 residential units, 598 parking spaces and retail offerings.

The South Loop has been on a roll this week with major proposals making their debut and with more details on the Jahn-designed tower for Michigan Avenue surfacing. Just this week alone, developers have presented plans for the Rafael Viñoly tower(s), a new hotel and apartment combo next to McCormick Place, and a 48-story apartment tower from SCB.

According to Crain's and the drawings, the tower is expected to contain both rentals and condos, but the exact breakdown between these residences is not known. It's also unknown when this new 86-story tower proposal will be presented to the public, but a community meeting may not be too far off. With a flurry of new exciting proposals, the South Loop area is one to truly keep an eye on in the coming months.
