The Nanjing Greenland Financial Center is a a relatively new super tall skyscraper built in Nanjing, China. When completed last April 2010, this building became the second tallest building in China and the fifth tallest in the world. It is a mixed use tower that features retail and office space.
The skyscraper is an 89-story building that stands 450 meters or 1,480 feet tall. It was designed by Marshall Strabala and Adrian Smith, both of whom also designed the Burj Khalifa, currently the tallest building in the world. The design for the skyscraper was the winner of the design competition held for the Nanjing Greenland Financial Center. The design during the post competition was taken over by Gordon Gill under the guidance of Adrian Smith, the three architects of whom were working at Skidmore, Owings and Merrill.
This mixed use tower was topped out in 2008. It features an observation deck on its 72nd floor at 287 meters above ground. This provides an unobstructed panoramic view of the Yangtze River as well as the two lakes situated nearby and the Ningzheng Ridge mountains.
The design of the skyscraper was inspired by the three key elements associated with Nanjing and the Chinese culture- the Yangtze River that flows through the city of Nanjing, the lush green landscape notable in the city as well as the dragon and column elements prevalent in Chinese architecture.
The central core of the skyscraper is embraced by two interlocking forms that stand for the image of dancing dragons. The exterior wall makes use of angled glass panes to suggest the dragon scales. The textured glass surfaces are separated by vertical and horizontal seams, which relates to the Yangtze River that separates the dragon forms.
