Don’t dismiss segmental vault houses as just Quonset huts or airplane hangars. The Quonset hut, developed and used during World War I and II, is a long half-circle of corrugated tin with a lightweight metal structure. Airplane hangars are considerably larger. These houses are different from the primitive wartime huts and deserve attention as a style for several reasons. First, Virginia Savage McAlester designates them as their own class of 21st-century modern style in the revised 2013 edition of her book, A Field Guide to American Houses. Second, many segmental vault houses can be found around California, including in Palm Springs. Lastly, these houses have a distinct character, derived from the arched roof shape, that clearly sets them apart from other contemporary structures.
