It was the first house built outside the stockaded town of Hadley and has looked nearly unchanged since 1799. It is also a memorial to three families, the Porters, Phelpses and Huntingtons, tied to it for ten generations.","narrative":"Forty Acres, also called the Porter-Phelps-Huntington House, is a three-story gambrel-roofed Colonial house on River Drive north of Hadley, Massachusetts. Moses Porter began clearing the land in 1752, and the house was the first built outside Hadley's stockaded town. Porter's son-in-law, Charles Phelps, a lawyer with knowledge of engineering and architecture, reshaped it between 1770 and 1799. He added a kitchen ell, turned the house to face the road, covered it in graduated clapboards, added a columned entrance porch and replaced the pitched roof with a gambrel roof. The house has changed little since. It was home to the Porter, Phelps and Huntington families for ten generations, including Bishop Frederick Dan Huntington, who used it as a summer residence. The Huntington family gave it to a foundation in 1955, and it is kept as a house museum with family furnishings and papers dating from 1697. Gardens lie to the north and south of the house.","period_of_significance":null,"architect_builder":"Moses Porter (builder, 1752); Charles Phelps (alterations 1770-1799)","architectural_style":"Colonial","criteria":[],"status_note":"Owned by the Porter-Phelps-Huntington Foundation since 1955 and preserved as a historic house museum; furnishings are entirely family possessions.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:11:53.507559-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/71/7954/63795471/content/electronic-records/rg-079/NPS_MA/73000303.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/73000303/992673eb5e-800.webp","url_1600":"https://nationalhistoricalregister.com/media/73000303/992673eb5e-1600.webp","licence":"CC BY 3.0","author":"John Phelan","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Porter-Phelps-Huntington_House,_Hadley_MA.jpg\" rel=\"noopener\">John Phelan</a>, <a href=\"https://creativecommons.org/licenses/by/3.0\" rel=\"license noopener\">CC BY 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Porter-Phelps-Huntington_House,_Hadley_MA.jpg"},"district":{"nrhp_refnum":"100008956","name":"Forty Acres and Its Skirts Historic District","url":"https://nationalhistoricalregister.com/districts/massachusetts/forty-acres-and-its-skirts-historic-district-100008956/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63795471","wikipedia":"https://en.wikipedia.org/wiki/Porter%E2%80%93Phelps%E2%80%93Huntington_House","wikidata":"https://www.wikidata.org/wiki/Q7231583"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/hampshire-county/porter-phelps-huntington-house-73000303/"}
