Set on the crest of a rise is this imposing three-story building faced with red brick and trimmed with light-toned terra-cotta. The first phase of the school (1917) was positioned so that its entrance bay terminates the vista up Runnels Street. When El Paso–based Trost and Trost designed the second stage addition (1929), they simply duplicated the 1917 building so that the school’s attenuated 10th Street elevation remains fixed on Runnels Street but also maintains overall symmetry by virtue of a second, matching eastern entrance bay.
To the east of the school at 1004 Johnson Street, the school’s former auditorium-gymnasium (1938, W. T. Strange Jr.), built with Public Works Administration funding, is a blocky, freestanding, one-and-a-half-story, symmetrical, Moderne building..
