Nina Tower is a twin tower of 80-storey and 42-storey high-rise building under construction in Tsuen Wan, New Territories, Hong Kong. Currently, the building is topped out, but other work, such as interior finishes have not yet been completed. The original version of this tower was called just Nina Tower and was supposed to be the tallest tower in the world at 518 m or 1,699 ft. However, due to its location near Chek Lap Kok Airport, the height was restricted down to the current 318.8 m or 1,046 ft.
The owner Chinachem Group later changed her plan to break it into two towers. The lower is known as Nina Tower, symbolising the late Nina Wang or Kung Yu Sum natively, the owner of Chinachem Group; the higher is Teddy Tower, symbolising her husband Teddy Wang, who was kidnapped and has since disappeared. Despite the different tower names, the whole development project is under the name of Nina Tower.
