This is an addition/remodel of a Ranch house in the Sleepy Hollow neighborhood of San Anselmo. The perennial question when modifying existing Ranch houses with their low roof profile is how to create height and interior volume without looking out of character. Our response in this case was to remove the flat ceiling in the entry to reveal the underside of the roof. And then in the main living area, we reversed the angle of the roof to create a “butterfly” space centered on the original ridge. The project also features a new garage with an ADU (Accessory Dwelling Unit) above, and an outdoor living area around a pool in the back yard.
