The house is listed with a construction date of c1830, determined by research, and its original use was as a farm.","why_significant":"The nomination argues the house is architecturally significant because it is a liberal and exacting execution of the Federal style, more elaborate than most structures erected in East Fallowfield Township during this period. Its elliptical fanlight over the main entrance is described as a formal interpretation of the Federal style usually found in townhouses rather than in the country, while most Federal farmhouses have transom lights instead.","narrative":"Built around 1830 as a farmhouse on Glen Rose Road in East Fallowfield Township, Chester County, this two-story Federal residence is four bays wide and roofed with a wood-shingled gable. Its lipped chimneys rise at both gable ends, and nine-over-six and six-over-six sash windows light the facade, with square windows in the gables. The single off-center main entrance is topped by an elliptical fanlight with fluted trim. The house was built during a period of cautious rural building, after the tight money of the War of 1812 and before the financial panic of 1837. The nomination treats the fanlight as the key distinction: Federal farmhouses of the area usually have transom lights, and an elliptical fanlight of this kind is more typical of town architecture. The house was evaluated as architecturally significant within the context of the East Fallowfield Township Multiple Resource Area, and its exterior features are described as intact.","period_of_significance":"1820-1860","architect_builder":null,"architectural_style":"Federal","criteria":[],"status_note":"Residence; condition and integrity recorded as excellent in the survey form.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:33.048395-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/85001148.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/85001148/f49ad2bfd2-800.webp","url_1600":"https://nationalhistoricalregister.com/media/85001148/f49ad2bfd2-1600.webp","licence":"CC0","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Passmore_Chesco.JPG\" rel=\"noopener\">Smallbones</a>, <a href=\"http://creativecommons.org/publicdomain/zero/1.0/deed.en\" rel=\"license noopener\">CC0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Passmore_Chesco.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71992549","wikipedia":"https://en.wikipedia.org/wiki/Mansel_Passmore_House","wikidata":"https://www.wikidata.org/wiki/Q6751583"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/chester-county/passmore-mansel-house-85001148/"}
