Its construction date is uncertain: possibly 1832 for the main body, or after 1863.","why_significant":"The nomination argues the house is an unusually sophisticated variant of the Italian Villa style. It is architecturally significant in its own right and reflects the taste attributed to the Harmon family, who owned the land. Its construction date is undocumented and subject to conjecture.","narrative":"This two-story brick house on East Prospect Road in Ashtabula began as a rectangular late Adam or Greek Revival building with a five-bay facade, shallow gabled roof, and an entrance with sidelights. Later changes added Italian Villa features, including a shallow three-bay round-arched wooden porch, bracketed eaves, and arched sidelights, plus a small central gable with an octagonal window. An L-shaped wing and a frame addition extend from the rear, and the interior was remodeled into four apartments. The land belonged to Edwin Harmon, a farmer, trader, and shipper who died in 1863, after which the portion holding this house passed to his son Francis E. Harmon. Whether Francis built the house after 1863 or part of it dates to a traditional but undocumented 1832 is unresolved. The house was listed because of its design, an unusually refined local version of the Italian Villa style that reflects the Harmon family's taste.","period_of_significance":"19th Century","architect_builder":null,"architectural_style":"Italian Villa (Tuscan), added to a late Adam or Greek Revival form","criteria":[],"status_note":"Condition listed as excellent and altered, on its original site; the interior was remodeled into four apartments and the form lists a private residence use.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:10.486368-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/75001312.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/75001312/268a8e9328-800.webp","url_1600":"https://nationalhistoricalregister.com/media/75001312/268a8e9328-1600.webp","licence":"CC BY-SA 3.0","author":"Alfredtwo","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Francis_E._Harmon_House_01.jpg\" rel=\"noopener\">Alfredtwo</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:Francis_E._Harmon_House_01.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71986675","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q137597551"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/ashtabula-county/harmon-francis-e-house-75001312/"}
