Marston in a Swiss or Tyrolean Chalet style.","why_significant":"The nomination argues the house is an excellent example of the Swiss Chalet style within the 'two-story house' subtype of Arts and Crafts single-family residences in Pasadena. It reflects the design, craftsmanship and materials of Arts and Crafts residential architecture. Key features include hillside siting, decorative wood details, half-timbering and a picturesque roofline, and the house retains integrity.","narrative":"Built in 1911 at the corner of Bellefontaine Street and Bellefontaine Place in Pasadena, this hillside house was designed by architect Sylvanus B. Marston for G. Roscoe Thomas, who developed other properties nearby. Its L-shaped plan steps down a sloping site, with a one-story entrance facade facing east and a fuller lower level to the west. The design draws on Swiss or Tyrolean Chalet vocabulary: front-facing gables, decorative wooden porch and balcony enclosures, half-timbering against stucco walls, and an octagonal stair tower with a pointed roof. Exterior changes have been minor, mainly altered window patterns and an enclosed former sleeping porch, and the interior has been rehabilitated to recover original features such as a fireplace and window seat. A 1939 garden cottage and a garage are not counted as historic. The house was listed for its architecture, as an example of Arts and Crafts residential design in Pasadena.","period_of_significance":"1911","architect_builder":"Marston, Sylvanus B.","architectural_style":"Swiss Chalet (Swiss or Tyrolean Chalet bungalow)","criteria":["C"],"status_note":"Still used as a single dwelling; a later garden cottage (1939) and a garage are non-contributing, and the exterior has had only minor alterations.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:27.824761-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/98000958.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/98000958/9f318ff0b5-800.webp","url_1600":"https://nationalhistoricalregister.com/media/98000958/9f318ff0b5-1600.webp","licence":"CC BY-SA 3.0","author":"TheCatalyst31","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:House_at_574_Bellefontaine_Street.JPG\" rel=\"noopener\">TheCatalyst31</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:House_at_574_Bellefontaine_Street.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123857508","wikipedia":"https://en.wikipedia.org/wiki/House_at_574_Bellefontaine_St.","wikidata":"https://www.wikidata.org/wiki/Q16995942"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/los-angeles-county/house-at-574-bellefontaine-st-98000958/"}
