Southwestern Bell’s “Valley” Exchange building was constructed in 1946 to handle the post-war increase in demand for residential telephone service. According to building permit records, Hanger Construction Co. was responsible for erecting the original 1946 Moderne style building. It is a simple two-story concrete structure faced with yellow-buff brick. The building’s starkness is relieved by a geometric patterned cornice, inset floral medallions at the beltcourse, and stylized dentils over the ground floor windows and entry. A one-story rear addition, designed by Preston Geren, was constructed in 1951. The second floor was added in 1957.
