It also cites the extensive Malibu Potteries tile work, the landscape design, the original furnishings, and the Rindge-Adamson family's role in California settlement and business.","narrative":"Perched on a promontory between the Pacific Ocean and Malibu Lagoon, this reinforced-concrete house was built in 1929 for Rhoda Rindge Adamson, daughter of Malibu ranch owner Frederick H. Rindge. Stiles Clements of Morgan, Walls & Clements designed it, combining Moorish pointed arches in the end wings with round Spanish arches in the central loggia. The courtyard plan was modified to take in views down the coast. Interiors include a vaulted, painted dining room ceiling, a stained cast stone stair vault, and steel windows with wrought iron detailing. Decorative tile made at nearby Malibu Potteries covers many floors and walls. The grounds were built up from sand dunes with imported soil and mature olive trees. The nomination also stresses the Rindge-Adamson family's part in California's settlement and business, and notes that the house, gatehouse, boathouse and bathhouse remain in original condition and in use under state ownership.","period_of_significance":"1900-1999 (specific dates 1923-1929: concept and plans 1923-1928, final plans January 5, 1929, construction 1929)","architect_builder":"Stiles Clements of Morgan, Walls & Clements (architect); MacDonald & Driver (general contractors); tile by Malibu Potteries","architectural_style":"Blend of Moorish and Spanish-Mediterranean architecture of the late 1920s","criteria":[],"status_note":"Occupied and in continual use and maintenance since 1929; described as in original, unaltered, excellent condition; owned by the California Department of Parks and Recreation and operated as a museum/park.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:31.820938-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/77000298.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/77000298/d51382be7c-800.webp","url_1600":"https://nationalhistoricalregister.com/media/77000298/d51382be7c-1600.webp","licence":"CC BY-SA 3.0","author":"Սէրուժ (Serouj Ourishian)","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Adamson_House.JPG\" rel=\"noopener\">Սէրուժ (Serouj Ourishian)</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Adamson_House.JPG"},"district":{"nrhp_refnum":"100002022","name":"Malibu Historic District","url":"https://nationalhistoricalregister.com/districts/california/malibu-historic-district-100002022/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123858905","wikipedia":"https://en.wikipedia.org/wiki/Adamson_House","wikidata":"https://www.wikidata.org/wiki/Q4680503"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/los-angeles-county/adamson-house-77000298/"}
