Chinese developer Wanda Vista is to build the ninth-tallest building in the US as part of the three-tower scheme designed by Studio Gang for a former rail yard in Chicago.
The tallest of the three glass towers will be 335m in height, and all three will contain 400 apartments and a hotel.
Studio Gang is the practice founded by architect Jeanne Gang. It specialises in low-energy designs and its buildings often have a social theme.
Vista’s design is inspired by a naturally forming crystal formation called "frustum", that is found in sapphires and fluorite.
The design provides views either towards the city or skywards with "multiple column-free corner rooms on each floor".
The project is hoping to achieve a LEED Silver rating.
The owner of Vista Residences is Wanda Group, China’s biggest private property developer, and local real estate company Magellan Development.
The building is due to be completed in 2019.
