38. Illinois: Aqua Tower
Aqua is an 82-story mixed-use, primarily residential skyscraper in the Lakeshore East development in downtown Chicago, Illinois. Designed by a team led by Jeanne Gang of Studio Gang Architects, with James Loewenberg of Loewenberg & Associates as the Architect of Record, it includes five levels of parking below ground. The building’s eighty-story, 140,000 sq ft (13,000 m2) base is topped by a 82,550 sq ft (7,669 m2) terrace with gardens, gazebos, pools, hot tubs, a walking/running track and a fire pit. Each floor covers approximately 16,000 sq ft (1,500 m2).

Aqua was awarded the Emporis Skyscraper Award as 2009 skyscraper of the year, and was shortlisted in 2010 for the biennial International Highrise Award. When it was completed, the skyscraper was the world’s tallest building designed by a woman. It was surpassed in 2020 by the nearby St. Regis, also located in Chicago and designed by Studio Gang Architects. (via Studio Gang)
