The one-part commercial block is a single street-level structure. In the late 19th and early 20th century, many such buildings were constructed with large plate-glass display windows for use as retail stores. False-façade buildings common to smaller communities in the western United States are generally one-part blocks as well. One-part public buildings are also widespread in Utah, including public libraries and city offices. “Block,” by the way, was a common turn-of-the-century term for even the smallest commercial structures.
