The 2½-story wood-shingled house has a gable roof with an integral leanto, a large center chimney, a five-bay facade facing south and a glazed center entry porch. It sits on Holt's Hill, set well back from the road, with a converted barn among its outbuildings. The estate grew into one of Andover's largest landholdings, reaching about a mile in radius from the house, and seven generations of the Holt family farmed it until the 1880s. The house is notable for its original framework, early interiors and remote setting. It was listed for its long link to a family prominent in the growth of eastern Andover and as an important example of how an early farmhouse form evolved, while keeping its integrity of design, materials, workmanship and setting.","period_of_significance":null,"architect_builder":"Nicholas Holt III (original owner and builder)","architectural_style":"Georgian","criteria":["A","C"],"status_note":"Present use is residential; a barn on the property has been converted.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:11:57.865863-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/19/7899/63789919/content/electronic-records/rg-079/NPS_MA/82004819.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/82004819/bccd775b09-800.webp","url_1600":"https://nationalhistoricalregister.com/media/82004819/bccd775b09-1600.webp","licence":"CC BY-SA 4.0","author":"User:Magicpiano","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:AndoverMA_HoltFarm.jpg\" rel=\"noopener\">User:Magicpiano</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:AndoverMA_HoltFarm.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63789919","wikipedia":"https://en.wikipedia.org/wiki/Holt_Farm_(Andover,_Massachusetts)","wikidata":"https://www.wikidata.org/wiki/Q14715550"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/essex-county/holt-farm-82004819/"}
