Skyscrapers are different from towers or masts because they are habitable. The term was first applied during the late-nineteenth century, as the public marvelled at the elevated, steel-frame buildings being erected in Chicago and New York, USA. Modern skyscrapers tend to be constructed from reinforced concrete. As a general rule, a building must be at least 150 metres high to qualify as a skyscraper.
