From charming cabins to lavish celebrity havens, award-winning architecture firm Buff & Hensman fashioned hundreds of dreamy California dwellings from 1950 to 2000. Among them, this Mid-century modern classic built in 1962 and recently restored and expanded with the utmost attention paid to maintaining its historic bones, complete with post-and-beam construction and walls of glass overlooking a large, open lot offering stunning canyon views.
