The Aqua Tower is located on the 200 block of North Columbus Drive. To capture views of nearby landmarks for Aqua's residents, Gang stretched its balconies outward by as much as 12 feet (3.7 meters. The result is a building composed of irregularly shaped concrete floor slabs which lend the facade an undulating, sculptural quality. By including an undulating exterior and specifying the use of fritted glass—which is etched with gray marks to make it easier for birds to see—the company has created a design that will help prevent birds from flying into windows. link
