In the 1950s, they were known for building schools, with a "lean and clean" style. The schools, generally one-story, had simple designs with classrooms on one side of a corridor, maximization of windows for lighting and ventilation, and shed, flat, or gabled roofs. In San Angelo, Texas, the Central High School was constructed with an open design, having 13 buildings on a campus. It was the first fully air-conditioned school in the country. Using the outdoors as an aesthetic, they designed a glass-walled and domed gymnasium in Brownsville, Texas for St. Josephs Academy. The editor of "ArchitectureWeek" stated that "they became known as masters of modern practice and construction management." In 1958, CRS moved their office to Houston from Bryan, Texas. They began designing hospitals and had designed school and university buildings in eight countries and 26 states by 1969.
