A. Quincy Jones, Architect | The Richard and Helen Arens House, 1950. City of Los Angeles Historic-Cultural Monument No. 720. High up in the Santa Monica Mountains of Brentwood, this landmark home is one of the best surviving examples of the forward-looking Mutual Housing Association’s postwar experiment. The architecture is elegantly simple: a low-slung horizontal roof with tongue-and-groove ceiling resting gently on composite beams and slender posts – the purest expression of form and function. Tasteful renovations are in keeping with the original design intent, and a rare hillside pool and hardscape provide panoramic views of the Santa Monica Bay, all the way to Catalina. Mills Act status ensues a substantial reduction in annual property taxes. 4 BD, 2 BA, 2,232 SF.
