Its builder combined Georgian, Roman Classical, Adamesque and Renaissance forms in an individual way. It is regarded as a unique variation of that regional type and one of the most interesting architectural remains in its district.","narrative":"Built in 1839 in Gastonville, Washington County, this three-bay, two-and-a-half-story side-hall house of random-coursed stone is a Post Colonial vernacular dwelling of Western Pennsylvania. The style lies between early log houses and the Greek Revival, and its builders borrowed freely from Georgian, Roman Classical and Adamesque forms, combining them in their own manner. A large chimney marks a back wing, probably a kitchen, and a second chimney stands at the far gable end. Stone lintels top the openings, and a circular stone block sits beneath the gable apex. Wide, unornamented eaves project boldly from the roof. A one-story recessed addition with a verandah was added later in the nineteenth century. The 2-over-2 windows are later 19th-century additions. The house is regarded as a unique variation of its type and among the most interesting architectural remains in its district, with value that is irreplaceable on a regional or national level.","period_of_significance":"1839","architect_builder":null,"architectural_style":"Post Colonial (Western Pennsylvania Post Colonial vernacular)","criteria":[],"status_note":"In good condition; altered; on its original site.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.022744-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/75001675.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/75001675/220cc78d34-800.webp","url_1600":"https://nationalhistoricalregister.com/media/75001675/220cc78d34-1600.webp","licence":"CC BY-SA 3.0","author":"Generic1139","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Dusmal_House.jpg\" rel=\"noopener\">Generic1139</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:Dusmal_House.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71995641","wikipedia":"https://en.wikipedia.org/wiki/Dusmal_House","wikidata":"https://www.wikidata.org/wiki/Q5316947"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/washington-county/dusmal-house-75001675/"}
