It was contracted in January 1906 and built by Charles M. Depew.","why_significant":"The nomination argues it is one of the few survivors of the early ocean-front beach and health resort development south of Golden Gate Park, where most other buildings were converted streetcars. It was built for the heir of J. Mora Moss, who built Oakland's Gothic Revival Moss Cottage. Its size, three-flat plan and sturdy construction let it survive as permanent income housing.","narrative":"Three stories tall with an attic, this three-unit residence at 1626 Great Highway faces the Pacific Ocean in San Francisco. Contracted in January 1906 and built by carpenter-contractor Charles M. Depew, it follows the Bay Area Shingle style, with a full-width angled bay and a cross gable. It was built as income property for the estate of Alfred T. Moss, with his guardian J. Mora Moss acting for him; the Mosses were relatives of the builder of Oakland's Moss Cottage. At the time, the beach south of Golden Gate Park was a loose community known as Carville, made up of abandoned streetcars adapted as clubhouses, restaurants and cabins. This solid three-story building appears to have been the only one of its height on that stretch of beach. Its generous size and strong construction allowed it to become permanent housing, and it remains one of the few traces of the area's early resort period. Replacement shingles and a later entry porch are the main changes to its original form.","period_of_significance":"1900-","architect_builder":"Charles M.
