The house was built in 1754 by Conrad Grubb, a weaver.","why_significant":"The nomination argues the house is a restored example of a Germanic house type that contained a home weaving industry. Its floor plan, fireplace placement and features such as the bake oven and loom-related details are presented as evidence of the builder's trade. The restoration is described as having high integrity.","narrative":"Built in 1754 by the weaver Conrad Grubb, the homestead in Montgomery County, Pennsylvania, consists of a two and one-half story house of local shale and sandstone with a brick addition, a barn with a milk house joined by a breezeway, a shed, a well house, an arched dirt cellar and a restored eighteenth-century garden. The house follows a three-room Germanic plan with a central fireplace whose heat reaches the formal and sleeping rooms, and it has an attached bake oven. Oak ceiling joists in the downstairs sleeping room bear the weight of the room where the heavy loom stood, and a drilled hole in an upstairs floor appears suited to a warping reel. The house is oriented to the sun to light the loom shed. Grubb farmed while working as a weaver and died in 1798 without heirs. The house is valued as a preserved example of a home industry setting and as a variant of a German house type brought by settlers. Its restoration is regarded as thorough.","period_of_significance":"1754","architect_builder":null,"architectural_style":"Germanic central fireplace house with three-room floor plan","criteria":[],"status_note":"Partially restored","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:28.771905-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/73001651.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/73001651/b3ffd645a1-800.webp","url_1600":"https://nationalhistoricalregister.com/media/73001651/b3ffd645a1-1600.webp","licence":"CC0","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Conrad_Grubb_Montco_PA.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:Conrad_Grubb_Montco_PA.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71998071","wikipedia":"https://en.wikipedia.org/wiki/Conrad_Grubb_Homestead","wikidata":"https://www.wikidata.org/wiki/Q5162523"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/montgomery-county/grubb-conrad-homestead-73001651/"}
