The house's walls are sandstone quarried on the site, with a copper roof and tidewater red cypress woodwork.","why_significant":"The nomination argues the house is a nationally significant work of Frank Lloyd Wright and one of only two Wright-designed buildings in western Pennsylvania, the other being Fallingwater. It is described as a particularly intact, well-maintained example of a high-end, customized Usonian house from the final decade of Wright's career. The nomination also notes its close relation to Fallingwater, which was built for the Kaufmann family and whose influence shaped the Hagans' interest in Wright.","narrative":"Set into the side of Kentuck Knob in the Kentuck District of Stewart Township, Fayette County, this one-story house was designed by Frank Lloyd Wright and built between 1954 and 1956 for I.N. and Bernardine Hagan. Its walls are sandstone quarried on the property, laid in rough-cut courses, and its crescent plan wraps around a west-facing courtyard. Cypress eaves with hexagonal openings and a copper roof define its profile, and the interior woodwork and built-in furniture are tidewater red cypress. The house is regarded as an excellent example of Wright's late Usonian residential design and as one of only two Wright buildings in western Pennsylvania, the other being Fallingwater. Its integrity of design and setting, and its connection to the nearby Fallingwater, are the chief reasons for its listing. The Hagans planted roughly 8,000 seedlings that turned the former farm fields into forest, and the landscaping remains intact.","period_of_significance":"1954-1956","architect_builder":"Wright, Frank Lloyd (architect); Jesse Wilson (stone mason); Herman Keys (contractor)","architectural_style":"Modern Movement (Wrightian)","criteria":["C"],"status_note":"The house is in excellent condition with little alteration and is open to the public through a tour program.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.047001-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/00000708_NHL.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/00000708/6349a4cd1e-800.webp","url_1600":"https://nationalhistoricalregister.com/media/00000708/6349a4cd1e-1600.webp","licence":"CC BY-SA 4.0","author":"Andre Carrotflower","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Kentuck_Knob_20190516_(24)_-_%22Courtyard-Carport%22.jpg\" rel=\"noopener\">Andre Carrotflower</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:Kentuck_Knob_20190516_(24)_-_%22Courtyard-Carport%22.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71994167","wikipedia":"https://en.wikipedia.org/wiki/Kentuck_Knob","wikidata":"https://www.wikidata.org/wiki/Q283587"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/fayette-county/hagan-i-n-and-bernadine-house-00000708/"}
