Looking like the San Andreas fault in the wake of the Big One, the principal walkway through Thom Mayne‘s Diamond Ranch High School makes its way through buildings that resemble craggy canyons of rock. Set on a sloping, hillside in Diamond Bar, Calif., about 30 miles east of downtown L.A., the structures are now a decade old. The design remains starkly beautiful (the metal exteriors shimmer, like a mirage, in direct sunlight), but like the surrounding desert environment, they are also quite forbidding. Diamond Ranch is serious testosterone architecture. There’s an abundance of corrugated metal, sharp angles and long, dim corridors that frame the outdoors in ways reminiscent of miner’s tunnels. And then there’s the relentless concrete, which is rarely interrupted by nature, even though the school’s principal public spaces all reside outdoors.
The vice principal who led us around the school — and who had been there since they first opened — said that while he enjoyed the shapes of the buildings, they did present plenty of challenges in terms of policing the campus. Odd angles, obscured staircases and dark passages provide plenty of places to smoke and suck face. On an aesthetic level, the combined greys of the concrete and metal leave many parts of the campus feeling frigid. Some classrooms had spectacular valley views, while others made do with indirect light and the sight of steel trusses. The students we spoke with, however, generally dug the structures. Reared on a lifetime of Star Trek and Star Wars and lots of other star stuff, they felt that the futuristic car-commercial look was kinda cool — and set their school apart from the bland concrete lumps elsewhere in the county.
I didn’t love everything about the school — the barren interior courtyards couldn’t be bleaker — but I totally respect it’s aggressive virility. Diamond Ranch is the Daniel Craig of architecture: hard and edgy, with a rugged sex appeal — the type of structures that can take a rope to the nuts and still say, “Come and get me motherfuckers.” And I gotta confess, I find that kinda hot.

Resembling a concrete guillotine: the school’s entrance.

Entering the school, and the main stretch of Panther Path. Very Death Star.

Looking back through the entry portal. Nature in the distance.

Echoing the shape of the jagged mountains in the distance.

Fantastic view…through a long, dark tunnel.

A view of the teacher’s courtyard. Not warm. Not friendly.

The stairs leading up to the athletic field.

The viewing stands. Very Triumph of the Will.

If I were a high school student, I’d be ever so tempted to paint a giant smiley face on that thing.

As hard as the buildings were, they did sport evidence that they were lived in. Here, a poster for a student dance interrupts the horizontal lines of Mayne’s corrugated panels.

Here a teacher customizes the stellar mountain views, by covering them up with student projects.

Cost effective, not: Changing these light bulbs requires a cherry picker.

This high school is about ten minutes from where I went to school. I actually came here to take my SATs back then. I remember thinking of how interesting all the forms were but all it really is pretty bleak once you’re in it. The massiveness is intimidating…especially when you’re headed off to such a big test.
i admit, its architecture is awesome, but it of course wears off and becomes a type of encarcerating place to us students. twas the alumni concensus. always reppin!
wounderful analogy with the miner coriddors. so much echo during passing periods.
