The house was built in three sections, the earliest about 1830-1831.","why_significant":"The nomination presents the property as an unusual, well-preserved example of an early 19th-century rural farm complex in southwestern Ohio. It cites the rational site planning, which uses local stone, the sloping hillside and a spring. It also ties the property to Daniel Unzicker, a Bavarian-born Mennonite farmer and preacher who settled the land.","narrative":"Near Oxford in Butler County, Ohio, this trimmed fieldstone farmhouse grew in three sections, beginning around 1831. The oldest part has walls about 20 inches thick, a gable roof and a pent roof across the south front. Later sections use more carefully coursed stone. Inside, the original tulip poplar and ash floors and wood trim survive, and the roof framing includes sapling poles and mill-sawn timbers. Daniel Unzicker, a Mennonite farmer and preacher from Bavaria, bought eighty acres of school land here and later expanded to one hundred sixty. His son Peter, a stone mason, probably helped build the house and farm buildings. The site also includes a barn, a springhouse that was probably the first structure built, and a fieldstone smokehouse. The complex is valued for its practical planning: the house sits against a hillside, opens to the south and east for protection from winter winds, and uses local stone and a spring to serve the farm's needs.","period_of_significance":"19th Century (ca. 1831)","architect_builder":"Daniel Unzicker (owner-builder); his son Peter, a stone mason, probably helped with construction","architectural_style":null,"criteria":[],"status_note":"Listed in excellent condition and occupied as a private residence; the house has been restored with new heating, plumbing and wiring.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:09.777933-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/74001404.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/74001404/3211a7abc0-800.webp","url_1600":"https://nationalhistoricalregister.com/media/74001404/3211a7abc0-1600.webp","licence":"CC BY-SA 4.0","author":"Andrew Clyde Armstrong","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Unzicker-Cook_House.jpg\" rel=\"noopener\">Andrew Clyde Armstrong</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Unzicker-Cook_House.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71986893","wikipedia":"https://en.wikipedia.org/wiki/Unzicker%E2%80%93Cook_House","wikidata":"https://www.wikidata.org/wiki/Q7897860"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/butler-county/unzicker-cook-house-74001404/"}
