Aqua is an 82-story mixed-use residential skyscraper in the Lakeshore East development in downtown Chicago, Illinois. Designed by a team led by Jeanne Gang of Studio Gang Architects, with James Loewenberg of Loewenberg & Associates as the Architect of Record. It includes one level of parking below ground. The building's eighty-story, 140,000 sq ft (13,000 m2) base is topped by a 82,550 sq ft (7,669 m2) terrace with gardens, gazebos, pools, hot tubs, a walking/running track and a fire pit. Each floor covers approximately 16,000 sq ft (1,500 m2). The Aqua was named the Emporis Skyscraper Award 2009 skyscraper of the year, and was shortlisted in 2010 for the biannual International Highrise Award.
Aqua is designed by Jeanne Gang, principal and founder of Studio Gang Architects, and it is her first skyscraper project. This is the largest project ever awarded to an American firm headed by a woman. Loewenberg & Associates are the architects of record, led by James Loewenberg.
The Aqua Tower is located at 225 North Columbus Drive, and is surrounded by high-rises. To capture views of nearby landmarks for Aqua's residents, Gang stretched its balconies outward by as much as 12 ft (3.7 m). The result is a building composed of irregularly shaped concrete floor slabs which lend the facade an undulating, sculptural quality. Gang cites the striated limestone outcroppings that are a common topographic feature of the Great Lakes region as inspiration for these slabs.
The building contains 55,000 sq ft (5,100 m2) of retail and office space, in addition to 215 hotel rooms (floors 1-18), 476 rental residential units (floors 19-52), and 263 condominium units & penthouses (floors 53-81). Aqua is the first downtown building to combine condos, apartments and a hotel. Strategic Hotels & Resorts had agreed to acquire the first 15 floors of hotel space upon completion of the building, but terminated its $84 million contract for the space in August 2008, citing significant changes in the economic environment.
The name 'Aqua' was assigned to the building by Magellan Development Group LLC. It fits the nautical theme of the other buildings in the Lake Shore East development, and is derived from the wave-like forms of the balconies; the tower's proximity to nearby Lake Michigan also influenced the name. Concrete Superintendent Paul Treacy, was nominated as one of Engineering News-Record's (ENR) top 25 news makers of 2008 for the design and implantation of the exterior formwork to mold the undulating façade of the Aqua.
Sustainability was an important factor in Aqua's design. Gang and her team refined the terrace extensions to maximize solar shading, and other sustainable features will include rainwater collection systems and energy-efficient lighting. The green roof on top of the tower base will be the largest in Chicago. The tower will seek LEED certification.
