Winnemucca Grammar School is a two-story brick structure, designed by architect Richard Watkins in the Prairie Style.

The Prairie Style was derived from he work of Frank Lloyd Wright. Features of this style include strong horizontal emphasis, parapets delineated with projecting caps, and original ornamentation based upon simple geometric or organic forms. The building relates to Frank Lloyd Wright's work in plan, massing and ornamentation.

The building remains a school for the lower grades, is in excellent condition, and has a high degree of integrity.
