Dorrance.","why_significant":"It is the only house on Courtlandt Place showing Mediterranean (\"California Style\") influence, and it reflects the architectural quality of one of Houston's earliest and most exclusive subdivisions. It is also a historical link to J. M. Dorrance, a prominent early 20th-century cotton broker and exporter. The nomination also highlights its architects, a firm that designed many notable Houston buildings.","narrative":"Built in 1913-14 at 9 Courtlandt Place in Houston, this two-story stuccoed brick house is one of 18 prominent residences on a tree-lined, divided boulevard laid out in 1906 as an exclusive neighborhood. Designed by the firm Sanguinet, Staats & Barnes, it shows Mediterranean influence, with a U-shaped front facade, arched windows with fanlights, an iron balcony and a low-pitched tile roof with wide eaves. Inside, a large oak-paneled receiving room serves as the main space for entertaining. The grounds include a garage and servants' quarters with horse stalls. It is the only house on the street with this Mediterranean character. It was the home of John M. Dorrance, a Massachusetts-born cotton broker who founded Dorrance and Co., one of the city's oldest and largest cotton firms, and who died there in 1935. The street's restrictive covenants have helped preserve its residential character.","period_of_significance":"1913-14","architect_builder":"Sanguinet, Staats & Barnes","architectural_style":"Mediterranean (\"California Style\")","criteria":[],"status_note":"Described as in excellent condition, unaltered, occupied and used as a private residence at the time of nomination.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:19.507722-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/62/9723/40972362/content/electronic-records/rg-079/NPS_TX/79002960.pdf"},"photo":null,"district":{"nrhp_refnum":"80004129","name":"Courtlandt Place Historic District","url":"https://nationalhistoricalregister.com/districts/texas/courtlandt-place-historic-district-80004129/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/40972362","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q110000992"},"indexable":true,"url":"https://nationalhistoricalregister.com/texas/harris-county/dorrance-john-m-house-79002960/"}
