Zifeng Tower, also known as Greenland Center-Zifeng Tower or Greenland Square Zifeng Tower, is a 450-metre building completed in 2009 in Nanjing, China. It is one of the 10 tallest building in the world. The 89-story building consists of retail and office space in the lower section, and restaurants, a hotel, and a public observatory near the top.
The 89 floor construction has space for offices, restaurants and other facilities. The Centre also has a 500-room hotel including outdoor swimming pool on the roof. A public observation deck on the 72nd floor, near the top of the building offers views of the Ningzheng Ridge Mountains, Xuanwu Lake, the Yangtze River.
The structure is made from steel and reinforced concrete. The form was derived from three central elements of the Nanjing history: the Yangtze River which flows through the city, the green garden landscape and the dragon as important part of Chinese culture. Tower’s exterior wall features angled panes of glass in staggered modules that looks like dragon’s scales. Vertical and horizontal seams separate the textured glass surfaces, relating to the clear water of the Yangtze River separating the great dragon forms.The tower’s shape is also highly functional, its triangular form relates to shape and size of the site while maximizing views of the mountains, lake and historic Nanjing buildings.
There is a shopping center spreading through floors 1-6 specialized for luxury goods. The building is business and financial centre and that we can see on the floors 10-41 which are all offices. There are two observation decks in the building, lobby on the 45-46 floor, and deck on 72 floor. The 6 star Intercontinental Hotel spreads through 20 floors, from 49 until 71. Floor under that International Hotel there is a coffee bar, with beautiful view over the city. On the top floor of the building there are Chinese restaurants and western restaurants. There are also Presidential suites, on 80 and 81 floors. The last floor is reserved for nightclubs. An outdoor swimming pool and garden are located on the roof of the tower’s podium. At night, the spire and tower atria will be lit and glow as a beacon in the Nanjing skyline, making the tower a radiant new landmark for the city.
