It was built in 1799 for mill owner John Lungren.","why_significant":"The nomination argues the house is a major example of Georgian style architecture with notable integrity, and that it is the finest five-bay Georgian design in the local area. It also describes the house as a landmark that dominated the mill village Lungren created and as an expression of the wealth and standing of its owner. Its retained Germanic building traits are presented as additional interest.","narrative":"Built in 1799 on the steep west bank of the east branch of Chester Creek, this five-bay granite house was erected for paper mill owner John Lungren, who also founded the surrounding mill village of Lenni. Its interior was completed in 1800. The house has paired end chimneys, a date stone on the south gable, and a central hall with a plan of four rooms per floor. Its windows combine Georgian small panes with narrower, deeper muntins of the Federal era, and the first-floor windows were fitted with hinges for shutters. Original details include six-panel doors, box locks, chestnut and poplar flooring, and an open stair with square balusters. A kitchen addition of 1811 was built to match the original. The house is regarded as the finest five-bay Georgian house in the area, and its size, materials and surviving integrity give it a dominant presence over the valley and the mill works.","period_of_significance":"1799-1800","architect_builder":"John Lungren (believed architect and builder)","architectural_style":"Georgian","criteria":["C"],"status_note":null,"vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:38.062414-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/96001197.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/96001197/ad2adcb886-800.webp","url_1600":"https://nationalhistoricalregister.com/media/96001197/ad2adcb886-1600.webp","licence":"Public domain","author":"User:Smallbones on English Wikipedia.","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:StonehavenDelco.JPG\" rel=\"noopener\">User:Smallbones on English Wikipedia.</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:StonehavenDelco.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71995033","wikipedia":"https://en.wikipedia.org/wiki/Stonehaven_(Media,_Pennsylvania)","wikidata":"https://www.wikidata.org/wiki/Q7619194"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/delaware-county/stonehaven-96001197/"}
