From 2005 to 2008 I restored a duplexed American Craftsman-style bungalow, also referred to as "arts and crafts". This style originated with Gustav Stickley (1858-1942) and plans were published in his magazine The Craftsman.
My brother lives upstairs and until I rescued the house from foreclosure he owned it for 30 years! The features of this style include low rooflines with over-hanging eaves; exposed structural elements as brackets and rafters; enclosed porch beneath an extended roof; interior spaces featuring built-ins as benches, cabinetry, fireplaces; beamed ceilings and extensive simplicity of woodwork. The house was duplexed sometime during the late 1940's, and now I have completed restoration of both up and down units.
