The name "Aqua" is in keeping with the nautical theme most of the buildings in the Lakeshore East development have: The Tides, The Shoreham, The Regatta, et.al.
But while those were conventional skyscrapers, Aqua is special.
At its heart it is the standard glass box we've seen before. But its surface is covered with ondulating balconies resembling ripples or waves. This is an appropriate homage considering the building's location near both Lake Michigan and the Chicago River. But the ripples are not without challenge. Much like each wave in the lake, each floorplate in Aqua is unique, thus construction is unusually complicated.
