Roehrig and built in 1895.","why_significant":"The nomination argues the house is a significant example of the work of prominent Pasadena architect Frederick Louis Roehrig under Criterion C. It combines American Foursquare form with Richardsonian Romanesque detailing and retains a high level of integrity. It is also described as the last of Roehrig's 'Millionaire's Row' houses still standing.","narrative":"Built in 1895 on Pasadena's former \"Millionaires' Row,\" this large single-family house at 297 South Orange Grove Boulevard was designed by architect Frederick Louis Roehrig. It is an oversized American Foursquare with Richardsonian Romanesque influences, with clapboard walls, a two-story curved bay, a hipped roof with a front dormer, and a front elevation faced partly in rock-faced Tehachapi sandstone. The arched entry, carved stone garlands, decorative ironwork, and shaped corbels reflect the craftsmanship of the period. Roehrig was a prolific architect who also designed Hotel Green and Castle Green, and this house is among his earliest surviving designs and the last of his Millionaires' Row houses still standing. It was listed for its architecture. Later changes, including a 1965 rear addition and rebuilt chimneys, are minor, and the house still reads as the home of a prosperous 1890s family. The altered carriage house at the rear is not counted as contributing.","period_of_significance":"1895","architect_builder":"Roehrig, Frederick Louis (architect)","architectural_style":"Late Victorian (American Foursquare with Richardsonian Romanesque influences)","criteria":["C"],"status_note":"Still used as a single dwelling; the detached carriage house/garage is non-contributing because of alterations, and the house has had minor alterations, mostly at the rear.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:29.539314-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/11000491.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/11000491/ddf61ea17c-800.webp","url_1600":"https://nationalhistoricalregister.com/media/11000491/ddf61ea17c-1600.webp","licence":"CC BY-SA 3.0","author":"Ellie Trevarthen","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Mary_E_Denham_House.JPG\" rel=\"noopener\">Ellie Trevarthen</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:Mary_E_Denham_House.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123857452","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q133289687"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/los-angeles-county/denham-mary-e-house-11000491/"}
