The stone section was built by John Hayhurst, possibly as early as 1742.","why_significant":"The house is presented as a typical early stone house of southeastern Pennsylvania that later received additions, and as a good example of regional style. General Sullivan of the Revolutionary forces encamped at the farm from December 20 to 25, 1776, before the attack on Trenton. The one-room stone school house is described as one of the few remaining early stone school houses of the region.","narrative":"Built of stone in Upper Makefield Township, Bucks County, by John Hayhurst, possibly as early as 1742, the two-and-a-half-story house was later enlarged with a frame section, probably built in the early or mid nineteenth century. The stone section has stucco over uncoursed masonry, and its interior keeps wide board floors, wood window reveals and cornice moulding, plus two stone fireplaces, one used for cooking. Beside it stands a one-and-a-half-story stone school house, built in 1804 and converted to a shed in 1873. General Sullivan of the Revolutionary forces encamped at the farm from December 20 to 25, 1776, just before the attack on Trenton, which gives the property its historical weight. Hayhurst, a minister among Friends who belonged to Wrightstown Meeting, is also associated with the house, which is regarded as a good example of regional stone architecture.","period_of_significance":"18th Century","architect_builder":"John Hayhurst (builder of the stone section)","architectural_style":null,"criteria":[],"status_note":"Frame section exterior has been altered with aluminum siding; the school house was converted to a shed in 1873.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.15484-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/74001759.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/74001759/2f9ef252b7-800.webp","url_1600":"https://nationalhistoricalregister.com/media/74001759/2f9ef252b7-1600.webp","licence":"CC BY-SA 3.0","author":"JERRYE &amp; ROY KLOTZ MD","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:HAYHURST_FARM.jpg\" rel=\"noopener\">JERRYE &amp;amp; ROY KLOTZ MD</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:HAYHURST_FARM.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71998806","wikipedia":"https://en.wikipedia.org/wiki/Hayhurst_Farm","wikidata":"https://www.wikidata.org/wiki/Q16994974"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/bucks-county/hayhurst-farm-74001759/"}
