About Home Insurance Building
The Home Insurance Building was built in 1885 in Chicago, Illinois, USA and destroyed in 1931 to make way for the Field Building (now the LaSalle National Bank Building). It was the first building to use structural steel in its frame, but the majority of its structure was composed of cast and wrought iron. It is generally noted as the first tall building to be supported, both inside and outside, by a fireproof metal frame. However, this may not be entirely correct as Ditherington Flax Mill was built as a fireproof metal framed building 88 years earlier. Due to the Chicago building's unique architecture and unique weight bearing frame, it is considered to be the first skyscraper in the world. It had 10 stories and rose to a height of 138 feet (42 m). In 1890, two additional floors were built on top of the original 10-story building.
