It has a cobblestone farmhouse begun possibly in the 1820s and finished about 1840, plus a barn and a wagon house/machine shed from the nineteenth century.","why_significant":"The farmhouse is argued to be an outstanding example of western New York cobblestone architecture from the middle period of the tradition, and a distinctive late Federal/early Greek Revival house with a Palladian-inspired cut-stone entrance. The farm also keeps the full 203 acres assembled by D.D.T. Warner in 1867, along with two historic outbuildings that reflect nineteenth-century sheep, hog, orchard and field-crop farming.","narrative":"Along Route 488 on the Phelps and Hopewell town line, this 203-acre farm centers on a cobblestone farmhouse dated 1840 on a stone in its front gable. Construction may have begun in the 1820s and continued over several years. The two-story main block and its side wing are faced with rounded stones laid in even horizontal courses with V-shaped mortar joints. The front door, framed by cut-stone Doric columns and a shell-like fanlight, is described as unique in Ontario County. Italianate porch and rear additions followed in the late 1860s or early 1870s under Daniel D. Tompkins Warner, son of Oliver Warner, who is credited with the house. A tripartite barn and a machine shed/wagon house survive from the nineteenth century. The acreage matches the holdings assembled by 1867 and was farmed for sheep, hogs, orchard fruit and field crops. The property stayed in the Warner family until 1947 and still operates as a dairy farm.","period_of_significance":"ca. 1840 - ca. 1900","architect_builder":"Oliver Warner","architectural_style":"Late Federal/early Greek Revival cobblestone farmhouse with later Italianate additions","criteria":[],"status_note":"Described as a full-scale working dairy farm; the farmhouse is occupied as a private residence and its interior is largely intact.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:45.647777-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/88002189.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75320556","wikipedia":"https://en.wikipedia.org/wiki/Oliver_Warner_Farmstead","wikidata":"https://www.wikidata.org/wiki/Q7087917"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/ontario-county/warner-oliver-farmstead-88002189/"}
