The Callison-designed Greenland Group headquarters in Shanghai, China, is expected to open in May, in time for the 2010 Shanghai World Expo.
The headquarters make up part of the 270,000m² mixed-use Greenland Riverfront CBD development, located on the Huangpu River adjacent to the Expo site.
The design features a rooftop deck and atrium on top of a two-storey office building. Suspended glass curtain blades reflect the sunlight during the day and resemble a glowing lantern at night.
The building also houses a four-storey retail centre, three office towers, a five-star Marriott hotel and two signature residential towers.
The hotel features an undulating façade simulating the flow of water.
The residential portion was opened last year while the office portion opened in March 2011, to be followed by the unveiling of a retail centre and hotel in May 2011, the company said.
Callison is an international architecture firm. Greenland Group is a real estate company based in China.
