Rice Field separates both the Junior School and the Academy, with each having their own distinct areas on campus.

In the Academy, the Quad, surrounded by academic buildings, serves as a gathering place for students. Facilities shared by grades K-12 include the Thurston Memorial Chapel, assembly halls, Dole Cafeteria, the Science Center, Kuaihelani and the Twigg-Smith Pavilion in Case Middle School, as well as various physical education facilities.
