Supertall buildings vie for dominance along Chicago’s skyline

When Miami-based developer Crescent Heights unveiled plans for a 76-story, 829-foot-tall skyscraper with 792 apartments, that building could lay claim to be the tallest in Chicago’s South Loop. This Rafael Viñoly-designed tower is the first of three that Crescent Heights is planning just south of Grant Park, according to Crain’s Chicago Business.

But only few days after Crescent’s plans became public, details surfaced about an even taller 86-story glass residential tower on 1000 S. Michigan Avenue, about a block from Crescent Heights’ proposed skyscrapers.

Last April that high rise’s developer, a joint venture between New York real estate firms JK Equities and Time Equities, paid $10.5 million for the 111-year-old eight-story Lighter Building, which is adjacent to their proposed tower. According to the JV’s application, the Lighter Building will continue to serve as office space. If the city approves 1000 S. Michigan, the joint venture intends to purchase a portion of the site for their tower from its current owner, First American Bank, according to Crain’s.

Architect Helmut Jahn designed this 506-unit tower, to be situated on a little more than an acre, to resemble four stacked boxes on its South façade. The 75-year-old Jahn has used this multi-step design approach before on a 41-story residential high rise in Chicago that was completed in 2008. The new tower proposal calls for condos on its top 60 floors and apartments on 21 floors. A parking garage with 598 slots would be in an 11-story rear extension to the tower.

Including its rooftop terrace, this tower would soar 1,030 feet, making it the Windy City’s fifth-tallest building. However, such claims are always transitory: Studio Gang’s architect Jeanne Gang has proposed a 1,140-foot-tall Vista Residences in Chicago, which would feature a trio of glass towers arranged in a row, with heights of 47, 71, and 93 stories. Gang told Dezeen magazine that she was inspired to mass the buildings by a formation called “frustum,” which resembles a pyramid without a pointy peak.

Thanks to a $45 million federal appropriation to the Smithsonian Institution, the Smithsonian Environmental Research Center in Edgewater, Md., has broken ground on what is expected to be one of the most energy-efficient laboratories in the country. The 69,000-sf lab is targeting LEED Gold and is expected to use 37% less energy and emit 37% less carbon dioxide than a similar building.
