The current building by CannonDesign, completed in 2003 at a cost of $44.6 million, is the newest high school in Orange County. Its design, frequently compared to an airport terminal, connects two otherwise separate structures built into the 50 acre (20 ha) site's gentle slope with glass-enclosed overhead and ground-level walkways. There are five separate levels, totaling 208,000 square feet (18,720 m²) with a courtyard-like space in between the two. All interiors are painted predominantly white, adorned with student artwork and porcelain tile walls, and colorful accents on classroom floors.
