When we think of cliffside homes, we generally cantilevered craftsmans in the Hollywood Hills or stunning seascapes viewed from sweeping balconies. This space from the architects at OPA, known as Casa Brutale, quite literally turns that vision on its head. Although set beside the sea and indeed perched upon a cliff, the house is actually carved out of the earth, with three walls surrounded entirely by the cliff itself. The resulting structure is a nod to Brutalist stylings in concrete and glass, while also realizing an architect's vision with a completely unique home.
