Skyscraper originally referred to the tall, main sail
of a ship
The structural definition is based on the fact that
the buildings have a steel frame
Today, it refers to a very tall and habitable
building
 There is no actual height which determines if a
building is a skyscraper
U.S. and Europe share a loose convention that 150
m tall is considered a skyscraper, while 300 m tall
is “supertall”

and better skyscrapers
