Studio Design Group's design for the historic Mission College Preparatory High School addition included a three- story, 70,000 SF building, doubling the size of the original school. A new gymnasium and locker rooms, classrooms, science labs, cafeteria and dining hall, and a subterranean parking garage in the multi-story building allowed the school to retain the existing athletic fields without having to acquire more property for the addition. The second phase consists of a seismic retrofit of the original 1926 unreinforced building , a Performing Arts Theatre and classroom modernization.
