China’s tallest tower, the willowy Canton TV building, opened this week ahead of the opening of the Asian Games in mid-November.
The 600m tall structure is made from steel columns infilled with concrete. Its tapered form is created by the top and bottom of the structure being twisted relative to each other.
The structure tapers from its elliptical base which is 60m wide and 80m long until it is just 27m wide at mid-height, its narrowest point. It then widens to a 40.5m wide by
54m long elliptical roof.
Five miniature buildings are suspended within the tower, and cathedral-like open-air spaces offer 360° views. Visitors can walk on an open-air SkyWalk staircase wrapped around the central concrete core.
Arup provided total engineering services to Information Based Architecture for the design of the structure.
