Located in California wine country, Roseland University Prep, a charter high school of 400 students, got its start in 2004 in an old warehouse—a dark, nearly windowless structure that had been minimally renovated. Still, the administrators and teachers created a highly successful learning environment for its predominantly Latino community, leading to a 95 percent average graduation rate. When the swelling student population outgrew the building, the school administration set their architectural ambitions high as well, hiring the San Francisco–based Aidlin Darling Design, a firm known for its attention to detail and craft in projects such as the Windhover Contemplative Center at Stanford University (record, February 2015). The architects designed a dynamic, expansive 30,800-square-foot building—under a tight public-school budget. “This has been one of our most rewarding projects, because we were able to make such a radical change,” says principal Joshua Aidlin. “It’s a scrappy building, sculpted and crafted from the cheapest materials, that is durable and flexible.”
