It was completed in 1861 for homesteader Samuel Martin and enlarged in 1929 with Julia Morgan as consulting architect.","why_significant":"The nomination argues the house is a rare stone example of Gothic Revival architecture in California, built when the style was usually translated into wood. It also reflects the settlement of Suisun Valley by Samuel Martin, the first settler to record a deed there. The site holds archeological value as part of a South Patwin Suisuni village, with a milling stone and a natural spring.","narrative":"Stonedene is a Gothic Revival house built of hand-hewn native stone on Suisun Valley Road in Suisun, California. Completed in 1861 for pioneer settler Samuel Martin, it was designed and supervised by a German stone mason. The original three-story house had 13 rooms, steep gables, and a front veranda. In 1929 a rear wing and solarium were added under consulting architect Julia Morgan, who matched the original stonework, extended the windows into French windows, and reroofed the house in gray slate. The grounds also include a Gothic Revival carriage house, a stone fence with tall entry columns, and large eucalyptus trees. Martin was the first purchaser to record a deed in the area and farmed the land for decades. The nomination also stresses the site's earlier history: it sits on part of a South Patwin Suisuni village, with a milling stone and natural spring on the property. A stone Gothic Revival house of this period is uncommon in California.","period_of_significance":"1861","architect_builder":"Samuel Martin; Julia Morgan (1929 remodeling); a German stone mason, name unknown, designed and supervised the original construction","architectural_style":"Gothic Revival","criteria":[],"status_note":"Altered by the 1929 remodeling and rear wing, which matched the original stonework.
