The Gothic Revival detailing was added about 1920 by H.F. Kolwes, who carefully reproduced the style, giving the house a much older look. It also belongs to the local context of community development and regional expansion, 1870-1941.","narrative":"This 1 1/2-story frame house at 1304 South Market in Brenham was built about 1883 for Samuel Schlenker and his bride, who later served as Washington County tax assessor for 22 years. It began as a vernacular L-plan dwelling with Italianate features such as arched windows with hood moldings, pedimented surrounds and a panelled bay window. H.F. Kolwes bought the property in 1919 and, after a visit to New York's Hudson River Valley, remodeled it around 1920. He added scrollwork bargeboards, spindlework, jigsawn brackets, turned finials and a full-width front porch with brick piers. The result is a Carpenter Gothic interpretation that is the only residential example of Gothic Revival architecture in Brenham and is rare in Texas. The house sits on a pier-and-beam foundation with weatherboard siding and an asphalt-shingled cross-gabled roof. A frame garage on the lot does not contribute to its historic character. The house remains in good condition and retains a high degree of integrity.","period_of_significance":"c.1883, 1920","architect_builder":null,"architectural_style":"Gothic Revival","criteria":["C"],"status_note":"Described as in good condition with a high degree of integrity; still used as a single dwelling.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:21.509643-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/25/9706/40970625/content/electronic-records/rg-079/NPS_TX/90000460.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/40970625","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q110002485"},"indexable":true,"url":"https://nationalhistoricalregister.com/texas/washington-county/schlenker-kolwes-house-90000460/"}
