Aqua is a prominent high‑rise in Chicago, United States. Rising to about 250 meters (approximately 819 feet) with 82 floors, it was completed in 2009. The tower was conceived and led by architect Jeanne Gang and her Studio Gang firm and gained attention for a facade treatment that departs from typical glass boxes.

Design and appearance

A defining element of the building is a rippling series of horizontal balconies that vary in size and shape from floor to floor. Cast in reinforced concrete, these projecting slabs create a sculptural silhouette that reads differently from each vantage point and produces deep shadow patterns on the exterior. The effect was intended to evoke natural forms and to respond to the building's lakefront setting.

Key characteristics

  • Height and scale: Approximately 250 m tall with 82 occupied stories.
  • Façade: Undulating, reinforced‑concrete balconies that form a textured skin.
  • Program: Mixed‑use tower combining residential units, hospitality and amenity spaces with street‑level retail.
  • Local rank: Noted as one of Chicago's taller buildings and commonly cited among the city's prominent modern towers.

Internally, the stepped balconies help provide private outdoor space for occupants while also influencing daylighting and views. The structure uses conventional high‑rise systems adapted for the heavier, articulated profile of its exterior balconies.

History and reception

Designed in the 2000s and finished in 2009, the tower was an early major commission that brought wider public recognition to Jeanne Gang and her office. Critics and the public praised the building for adding a distinctive, humanized form to the skyline where rectilinear towers dominate. It has been the subject of architectural discussions about materiality, context and the role of ornament in contemporary skyscrapers.

The building's visibility on the lakefront and its sculptural profile make it a frequent reference in surveys of recent Chicago architecture.
