Robert Roeschlaub organized one of his finest schools around a central court, with square corner entry towers topped by bell-shaped domes with nipple finials. The brick walls blend into rich layers of stone trim and a terracotta frieze. A strong cornice separates the two-and-one-half-story base from the towers and parapeted gable dormers. Two large additions, each reflecting its own era, complement the original.

When the school board announced plans to demolish their school, students here helped persuade the Denver Landmark Preservation Commission and the Denver City Council to declare it the first locally landmarked school. Roeschlaub, Colorado's leading institutional architect of the nineteenth century, designed at least a dozen Denver schools, including the Emerson School (1884), East 14th Avenue and Ogden Street, which features a large south wall sundial reminiscent of the one installed on the 1993 addition to Dora Moore.
