The original building, designed by local Austin architect Jasper N. Preston, was constructed with over six million pressed bricks and white limestone accents. The building contains two porticos on the southern and eastern facades, which contain large Richardsonian-style arches that were reputed to be the largest in Texas. The facade contains three limestone busts of Driskill and his sons; J.W. “Bud” Driskill facing Brazos Street, A. W. “Tobe” Driskill facing an alley on the west side, and Jesse Driskill facing Sixth Street, whose bust is surrounded by decorative carvings including longhorns on the gable ends.
