Brutalist

This architectural label, whose name comes from the French term for raw concrete, béton brut, originated as a way to highlight buildings that were particularly honest in conveying their use, structure, and material composition. Paffard Keatinge-Clay’s 1969 addition to the San Francisco Art Institute in Russian Hill is a good example, with studio spaces defined by structural concrete bays and a rugged roof deck. Another choice example: the Glen Park BART Station.
