The Home Insurance Building, completed in 1884 in Chicago, Illinois, is generally noted as the world's first skyscraper. It was the first tall building, (originally 138 feet and 10 stories) to be supported by a fireproof metal frame. The building weighed only one-third as much as a comparable stone building, (supported by its walls) allowing it to climb higher without crushing its base. In 1890, two additional floors were added, making the building 190 feet in total. It was demolished in 1931. The Field Building, a 45-storey, 535-foot skyscraper completed in 1934 now occupies the site at 135 South LaSalle St.
