It is described as the first house built in the new township of Larkspur, tied to the 1880s real estate boom. It is also linked to Thomas Dolliver, to the builder Gustave Nagel, and to the family's donation of redwood groves as public parks.","narrative":"Built in 1888, this two-and-a-half-story redwood house on Madrone Avenue in Larkspur was a summer home for Thomas Dolliver, a San Francisco shoe merchant who arrived in California during the gold rush. Gustave Nagel, who later built the Larkspur Hotel and the original Corte Madera school, constructed it, and local accounts describe it as the first house in the newly platted township. The design is a restrained California version of the Stick-Eastlake style, with angular lines, patterned shingles, bullseye trim and a wide double veranda. Much original material survives, including square nails, rolled glass windows, brass hardware, redwood floors and a brick fireplace. The Dolliver family's later gifts of adjoining redwood groves to the town created the parks that still preserve the setting. The house reflects how prosperous San Franciscans built summer retreats in Marin County during the 1880s land boom.","period_of_significance":"1800-1899","architect_builder":"Gustave Nagel","architectural_style":"California modified Stick-Eastlake","criteria":[],"status_note":"Condition listed as good and altered, on its original site; the form notes it was undergoing interior remodeling only, and the interior retains its original eight-room plan.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:31.703981-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/78000703.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123859672","wikipedia":null,"wikidata":null},"indexable":true,"url":"https://nationalhistoricalregister.com/california/marin-county/dolliver-house-78000703/"}
