The Wuhan Greenland Center[5] is a planned 636-meter (2,087 ft), 126-floor mixed-use skyscraper currently under construction and scheduled for completion in 2019. If completed as planned, it will be among the world's tallest structures, and one of the world's tallest buildings by occupiable floor height. The Phoenix Towers are proposed supertall skyscrapers planned for construction in Wuhan.
