Aqua Building in Chicago. Part of the Lakeshore East District where the Chicago River meets Lake Michigan. Adjacent to Millennium Park and the Loop Business District on Columbus Drive. Designed by Architect Jeanne Gang, her first skyscraper and the tallest skyscraper in the world designed by a woman. 86 stories mixed use residential/hotel. Irregularily shaped balconies create the wave like appearance. It’s super cool.
