These two-story buildings housed the administration, high school, elementary school, dining hall, and science hall. Constructed of boulder concrete with some reinforcing, the structures are in the then popular Spanish Mission Revival. This was the style of choice for the Catholic Church in Hawaii during the 1920s, the result of its associations with earlier church endeavors in Mexico, California, and the American Southwest, as well as the style having been sanctioned by architects such as Bertram Grosvenor Goodhue as a form appropriate for warm climates. All the buildings sit on raised foundations and feature pent-roofed front lanai, providing an open face to the public. The central administration building is flanked by the two pavilion-shaped classroom buildings, offering an impressive visual introduction to the campus.
