Construction started in June of 1888, and ended September 1889.
The building had an internal steel frame as the load-bearing structure, and the architect reserved the two top floors for his own use to take away any suspicions that the new owner might have about the strength of the building.
The Tower Building was constructed as the first all-metal-framed building in New York City.
It was built on a plot only six meters wide, which ruled out the use of massive masonry walls.
