It also includes a fountain, a wooden orange packing house, a decorative pool and a block wall.","why_significant":"The estate is argued to be significant under Criterion C as the work of master architect Irving Gill. With the Dodge house demolished and the Scripps house heavily remodeled, it is described as the best preserved major residence of his mature style. It also shows unusual decorative touches attributed to Marie Clarke's influence, and Mrs. Clarke was a founder of the Hollywood Bowl.","narrative":"Built in 1921 on former orange grove land in Santa Fe Springs, this two-story residence was designed by architect Irving Gill for Chauncey and Marie Clarke. The house is a U-shaped block of poured-in-place reinforced concrete, with plain walls and cubic masses outside and an interior courtyard closed on one side by a porte cochere. The courtyard is more ornate, with cast concrete window surrounds, Chinese wood balcony railings, a Mayan-pattern magnesite floor and leaf impressions in the wall coating. These details are attributed to Mrs. Clarke's influence. The 3.11-acre grounds also hold a fountain, a wooden orange packing house that predates the residence, and a decorative pool. The estate is considered significant as the best preserved major residence from Gill's mature period, since his Dodge and Scripps houses were lost or heavily altered. The Clarkes lived here only from 1921 to 1923, after oil was discovered nearby.","period_of_significance":"1921","architect_builder":"Gill, Irving John (Gill and Pearson)","architectural_style":"Mission Reduction (reductive Mission Revival) - Irving Gill","criteria":["C"],"status_note":"Current function is listed as work in progress; the house was undergoing a rehabilitation program, and the pool was remodeled in 1989 as a decorative element.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:28.211779-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/89002267.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/89002267/377f8d3752-800.webp","url_1600":"https://nationalhistoricalregister.com/media/89002267/377f8d3752-1600.webp","licence":"CC0","author":"Northwalker","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Clarke_Estate_SF_Springs_CA_from_Front.jpg\" rel=\"noopener\">Northwalker</a>, <a href=\"http://creativecommons.org/publicdomain/zero/1.0/deed.en\" rel=\"license noopener\">CC0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Clarke_Estate_SF_Springs_CA_from_Front.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123859037","wikipedia":"https://en.wikipedia.org/wiki/Clarke_Estate","wikidata":"https://www.wikidata.org/wiki/Q26955587"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/los-angeles-county/clarke-estate-89002267/"}
