In 1991, the Harvard School for Boys and the Westlake School for Girls merged to become Harvard-Westlake, a university preparatory day school consisting of two campuses with approximately 1,600 students. Grades 7–9 are taught at the former Westlake campus in Holmby Hills, and grades 10–12 are taught at the former Harvard campus in Studio City. Most students participate in extracurricular activities such as the visual and performing arts, as well as athletic teams.

Rugby Auditorium is a small theater, remodeled from a flat-floored assembly room into a multi-purpose auditorium. The floor was dug out to provide a sloped seating area and stage. The ceiling was shaped for beneficial overhead reflections. The side walls were slanted in at the top and facets incorporated to provide early reflected sound. The result is a dramatic, jewel-like appearance that was relatively easy to build, in spite of its apparent complexity. The rear wall is made of wood slats over a cloth facing and a 1-inch fiberglass panel. The hall provides good support for both speech and musical performances.
