The Council on Tall Buildings and Urban Habitat released a list of what are expected to be the 20 tallest buildings in the world in 2020, and the buildings are getting so tall that the council had to coin a new word. From the press release:
The term "supertall" (which refers to a building over 300 meters) is thus no longer adequate to describe these buildings: we are entering the era of the "megatall." This term is now officially being used by the Council to describe buildings over 600 meters in height, or double the height of a supertall.But why stop there? Kingdom Tower, the tower that's expected to be the world's tallest, will clock in at a height of more than a kilometer. May we suggest the term "übermegasupertall"? Chicago, of course, isn't expected to have any entries in the new megatall category; the only building in the western hemisphere to make the list is One World Trade Center. However, Chicago firms Adrian Smith + Gordon Gill, SOM, and Murphy/Jahn are all represented.
