At 82 stories and over 1.9 million sf, Aqua Tower is one of few high-rises in the world that creates a community on its facade. With a hotel, apartments, condominiums, parking, offices, and one of Chicago's largest green roofs, this multi-use tower demonstrates both architectural and technical achievements. Its outdoor terraces-which differ in shape from floor to floor based on criteria such as views, solar shading and dwelling size/type-create a strong connection to the outdoors and the city, as well as form the tower's distinctive undulating appearance.
