Chaffey Joint Union High School District

This transformative project at Alta Loma High School included the careful removal of a portion of the existing gymnasium while the school was in session. The new 22,185-SF gym includes a three-court gymnasium with a lobby, restrooms, and storage areas replacing the previous two-court gymnasium at the heart of the high school campus. The expanded gym provides seating for 1,500 spectators on telescoping bleachers to either side of a central CIF-ready competition court. When the bleachers are retracted, the design allows for the school’s use of three full basketball courts simultaneously.
