1884 - First metal-framed skyscraper - The Home Insurance Building is generally noted as the first tall building to be supported, both inside and outside, by a fireproof metal frame.

...The most expensive and probably the most substantial of the structures that can be included in this year's list in the new office section is the ten-story building being erected at the northeast corner of La Salle and Adams streets, for the Home Fire-Insurance Company of New York, after plans drawn by Architect W. L. B. Jenney. It has a frontage of 138 feet on La Salle street and ninety-six feet on Adams street, with a twenty-two-foot wing running north to the alley. The basement and first story are of Maine gray granit, rock-faced, and above that the outside walls are of Trenton pressed brick, elaborately and ornately trimmed with McArthur brown-stone and terracotta. The structure is entirely fire-proof, no wood of any kind being used in interior construction, and it will be under roof in a few days.
