"Stormy Seas" Aqua Building ~ Chicago, Illinois ~ USA Stormy Seas at the Aqua Building. The Aqua building is a 82 story mixed use residential skyscraper in downtown Chicago. The design team was led by Jeanne Gang of Studio Gang Architects. The building has a really interesting and unique design. The balconies have a wave shape that makes the building look like it is a series of waves. Anybody feel like they need to put on a life jacket? All comments are welcome.
