This, Alfred Giles's last work, is a Renaissance Revival design, highlighted by a giant order Corinthian colonnade on all four facades. The strong horizontal line of the cornice reflects the open flat landscape of the South Texas brush country. The exterior is enhanced by the contrast between the deep red brick walls and the white colonnade and cornice. The Hedrick addition is a long, one-story modernist box with horizontal strip windows under a continuous concrete canopy, in stark contrast with Giles's classicism.
