Initially located on church property at Tenth and Liberty Streets, the high school moved to a new three-story building at 1770 Mt. Ephraim Avenue in 1952. The new school building was designed by Earley & Houwen Associates, and its estimated $1 million cost borne by donors, including Catholic-owned businesses which donated materials and labor. The cornerstone was laid August 8, 1951, and the school formally dedicated November 27, 1952, while the wing containing the cafeteria, auditorium, and gymnasiums was still under construction.
