It sits on a rock-face stone foundation and is also known as the Eikenberry House.","why_significant":"The nomination presents the house as an outstanding example of Eastlake decorative detail, especially on its veranda and enclosed porch. It was the town home of a retired farmer from a pioneer Darke County family. The house is also reported to have had the first flush toilet in Greenville.","narrative":"Built in 1882, this T-shaped brick house at 209 Washington Street in Greenville, Ohio, rests on a rock-face stone foundation and is noted for its Eastlake decoration. The forward leg of the T is surrounded by a veranda and enclosed porch, the most striking part of the design. The veranda has table-leg columns, arches of intricate turning and gouge work, carved gable ends and turned balusters, and it keeps its patterned slate roof. Windows are one-over-one double-hung sash with hoodmoulds and stone lug sills, and the eaves carry brackets. Benjamin Franklin Coppess, grandson of pioneer Adam Coppess, who came to Darke County in 1819, was a successful farmer with 300 acres. He and his wife Maria moved to town and built the house. It is reported to have had the first flush toilet in Greenville. The interior is well-preserved and rather austere Victorian. Later changes include a shortened veranda, an extended side porch, removed cresting and a rear shed addition.","period_of_significance":"1882","architect_builder":null,"architectural_style":"Eastlake","criteria":[],"status_note":"Private residence, occupied at the time of nomination; altered, with the original veranda shortened and roof cresting removed.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:09.205057-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/78002052.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/78002052/b21f5816d4-800.webp","url_1600":"https://nationalhistoricalregister.com/media/78002052/b21f5816d4-1600.webp","licence":"Public domain","author":"Nyttend","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Benjamin_Franklin_Coppess_House,_Greenville.jpg\" rel=\"noopener\">Nyttend</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Benjamin_Franklin_Coppess_House,_Greenville.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71987965","wikipedia":"https://en.wikipedia.org/wiki/Benjamin_Franklin_Coppess_House","wikidata":"https://www.wikidata.org/wiki/Q4888625"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/darke-county/coppess-benjamin-franklin-house-78002052/"}
