The campus originally consisted of the original buildings built in the 1910s and 1920s, many of which were replaced in the 1960s by the newer two-story C, D, E, G, F, R, and S Buildings. In the early 1950s, the administration and library buildings were added. In the mid 1950s, the upper campus was built along with a new cafeteria (A building). The upper campus was used as the elementary school, until the new elementary school opened down the street in 1999. In 1958, the shop buildings were added. In the 1960s, the newer two-story four wing C, D, E, G and F buildings replaced the old three wing building. Around the same time, the school added bleachers to Julian Yates field along with the R and S buildings replacing old ones, and the new state of the art Ellison Onizuka Gymnasium opened (N building) in the early 1970s. Not long after, a new locker room and band room were built right above Julian Yates field (Q Building). The only two original buildings remaining on the campus today are the Ag building and one on the upper campus, now Konawaena Middle School.
