The form dates its construction to circa 1717, when Dielman Kolb purchased the 150-acre tract on which he built the house.","why_significant":"The nomination argues the house is a representative example of the eighteenth-century Germanic house type of the area, with proportions governed by geometric ratios and a floor plan that departs from the normal three-room arrangement. It also states the house has characteristics of unusual interest not seen in any other local building and is worthy of further architectural study.","narrative":"Built around 1717 by Dielman Kolb, an early settler in the Skippack Creek area, this gambrel-roofed farmhouse sits in a shallow hollow near Lederach in Lower Salford Township. It follows the central fireplace Continental type common to the region, with its kitchen at the far end and a large formal room opposite. Its proportions are described as a generated square, derived from geometric ratios associated with German building practice. The floor plan departs from the normal three-room layout: the front half is divided by two partitions into three areas whose purpose is not known, and the large formal room sits on the north side without a fireplace. The cellar has an unusually wide stair, probably for lowering bulk goods, and small splayed windows. Later changes include a late nineteenth-century remodeling that converted the gambrel into an A-frame roof, and a small summer kitchen on the east corner. The house was listed for its eighteenth-century Germanic architecture and its unusual plan features.","period_of_significance":null,"architect_builder":null,"architectural_style":"Germanic central fireplace house, gambrel roofed","criteria":[],"status_note":"The house is in the process of restoration; the form describes its condition as fair and altered.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.399264-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/73001647.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/73001647/da7987a1a1-800.webp","url_1600":"https://nationalhistoricalregister.com/media/73001647/da7987a1a1-1600.webp","licence":"CC BY-SA 3.0","author":"Shuvaev","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Dielman_Kolb_Homestead_01.JPG\" rel=\"noopener\">Shuvaev</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:Dielman_Kolb_Homestead_01.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71996215","wikipedia":"https://en.wikipedia.org/wiki/Dielman_Kolb_Homestead","wikidata":"https://www.wikidata.org/wiki/Q5274921"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/montgomery-county/kolb-dielman-homestead-73001647/"}
