It began as a 1913 redwood bungalow and was remodelled and enlarged in 1923 to designs by Albert Farr.","why_significant":"The nomination argues the house is significant for its English Period Revival styling and as an example of the work of San Francisco Bay Area architect Albert Farr. It is the only known Farr work in Santa Cruz County. It is also tied to Dr. William A. Phillips and Dr. William E. Musgrave, two prominent physicians.","narrative":"Riverwood is a Tudor Manor style country house beside the San Lorenzo River near Ben Lomond. It grew in stages from Phillipshurst, a 1913 redwood bungalow built by Dr. William A. Phillips, a retired physician known as the Father of the San Lorenzo Valley. In 1923 Dr. William E. Musgrave and his wife bought the property and hired San Francisco architect Albert Farr to remodel and greatly expand it. The result is about 10,000 square feet with a Great Hall, a crenellated tower house, Tudor arches, Cotswold roofs and shingled walls. John McLaren, designer of Golden Gate Park, laid out the gardens on what was then 150 acres. From 1936 the estate served as a school and home under the name Blake Hammond Manor, until 1969. The house is considered the only known Farr work in Santa Cruz County and the area's most impressive example of the Bay Area tradition. Later owners restored it, and about 7.5 acres remain.","period_of_significance":null,"architect_builder":"Albert Farr","architectural_style":"Eclectic American Tudor Manor House (English Period Revival), with Bay Area tradition shingle treatment","criteria":[],"status_note":"Occupied as a private residence; described as in excellent condition, with the Riverwood sections restored to their original condition and design.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:27.448427-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/83004369.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123861887","wikipedia":null,"wikidata":null},"indexable":true,"url":"https://nationalhistoricalregister.com/california/santa-cruz-county/phillipshurst-riverwood-83004369/"}
