Changsha IFS Tower T1 is a skyscraper in Changsha, Hunan, China. It is 452 metres (1,482.9 ft) tall. Construction started in 2013 and completed in 2017. It is the 16th tallest building in the world and the tallest in Hunan. IFS stands for 'International Finance Square'. This twin-tower development is based on Harbour City, a hyper-connected retail development in Hong Kong. The Changsha complex will sport an underground network of linkages to a future interchange hub (Wuyi Square Station) for Changsha metro lines 1 and 2. The same underground passageway will connect with one of the busiest pedestrian streets in China — Huang Xing Road Pedestrian Shopping Street. (Source: Wikipedia.org, CC BY-SA)
