William Hammond built it about 1719 on land leased from Philipsburg Manor, with additions in 1835 and 1860.","why_significant":"The nomination argues it is an early 18th-century farmhouse and one of only two surviving Philipsburg Manor tenant dwellings, out of about two hundred originally. It was also the homestead of the locally prominent Hammond family, including James Hammond, a Revolutionary War militia colonel. It offers insight into the county's 18th-century vernacular architecture.","narrative":"Built around 1719 by William Hammond, this small frame farmhouse in Eastview, near Hawthorne, was a tenant dwelling on the Philipsburg Manor. Hammond reportedly built it without a basement so it could be moved if his lease ended. The house has a five-bay front porch, a central section with two later wings: a detached cottage moved and joined to it in 1835 as a kitchen wing, and an east wing added in 1860. Inside are wide-board floors, large fireplaces and 18th-century paneling in the parlor. It is believed to be one of only two surviving Philipsburg tenant houses, from about two hundred that once stood on the manor. Hammond's son James, who inherited the farm, commanded the First Regiment of Westchester Militia in the Revolution and was held prisoner by the British for eighteen months. The family kept the property for several generations. The county historical society repaired it in 1926 and now opens it to visitors.","period_of_significance":"1700-1799","architect_builder":"William Hammond","architectural_style":null,"criteria":[],"status_note":"Owned by the Westchester County Historical Society and open to the public as a museum; the form lists condition as fair and altered, with the occupancy box marked unoccupied.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:43.133714-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/80002790.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80002790/95ad47ca21-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80002790/95ad47ca21-1600.webp","licence":"CC BY-SA 3.0","author":"Daniel Case","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Hammond_House,_Hawthorne,_NY.jpg\" rel=\"noopener\">Daniel Case</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:Hammond_House,_Hawthorne,_NY.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75323045","wikipedia":"https://en.wikipedia.org/wiki/Hammond_House_(Eastview,_New_York)","wikidata":"https://www.wikidata.org/wiki/Q5645846"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/westchester-county/hammond-house-80002790/"}
