If you are a Denver resident, you probably drive by this building all the time, but you would have had to carefully catch it out of the corner of your eye as you fly by on 18th Ave!

Usonian is the name applied by Frank Lloyd Wright to the architectural style he developed in the 1930s. It was intended to be a new vernacular U.S. style aimed at a futuristic utopia, hence US-onia. The other variant modernist style for the time period is called International style.

It is an outstanding example of a Usonian office building, the jutting eaves, the floor to ceiling windows, the garden, the clerestory windows. . .

This structure bears a strong resemblance to Victor Hornbein’s Usonian design, the Ross-Broadway Library from 1951. I have never seen this office building listed as a Hornbein design, but I at least assume it is from the same time period.
