[14] To capture views of nearby landmarks for Aqua's residents, Gang stretched its balconies outward by as much as 12 ft (3.7 m).

[15] The result is a building composed of irregularly shaped concrete floor slabs which lend the facade an undulating, sculptural quality.

[2][16] Gang cites the striated limestone outcroppings that are a common topographic feature of the Great Lakes region as inspiration for these slabs.

[2] Concrete Superintendent Paul Treacy, was nominated as one of Engineering News-Record's (ENR) top 25 news makers of 2008 for the design and implementation of the exterior formwork to mold the undulating façade of the Aqua.

Gang and her team refined the terrace extensions to maximize solar shading, and other sustainable features include a water-efficient irrigation system and energy-efficient lighting.

These features included bamboo flooring which was better to produce than hardwood, Greenguard certified HanStone Quartz countertops and plumbing fixtures that would reduce the number of gallons per flow for water conservation.

He found that having an edge-form steel plate would guide the pour and once it was done drying it could be snapped back into a straight plane and reused for different curves on the other balconies.

[26] A function of the curve balconies is that they protect the building from harsh winds which happens to be one of the most difficult challenges in skyscraper engineering.
