Peirce and designed by the Boston firm Coolidge, Shepley, Bulfinch and Abbott. It is now Henderson House, a conference center of Northeastern University.","why_significant":"It is one of about a dozen large estate houses remaining from Weston's late 19th and early 20th century estate era, and the last of the grand Weston estate mansions to be built. It is the only remaining Tudor-style estate house in the town and its largest and most elaborate example of the style. The house is also notable for its largely intact condition and for the extensive original plans and sketches that survive from its architects.","narrative":"Set on a rock ledge at the high point of a nearly six-acre parcel in Weston, Massachusetts, this Tudor Revival mansion was built in 1925-27 for Edward R. Peirce. The Boston firm Coolidge, Shepley, Bulfinch and Abbott designed it after an earlier fire. Its first story, porte-cochere and porches are stone, the upper story and gables are half-timbered, and the roof is slate. Interiors are Colonial Revival, with a two-story stairhall and a double staircase. The house later became Henderson House, a conference center of Northeastern University. It is valued as the last of Weston's grand estate mansions, the town's only remaining Tudor-style estate house, and its largest and most elaborate example of that style. The Peirce estate once covered almost 325 acres across Weston and Wellesley and stayed in private hands into the late 1950s. The house survives largely unaltered, and original architectural plans and sketches have been preserved.","period_of_significance":null,"architect_builder":"Coolidge, Shepley, Bulfinch and Abbott","architectural_style":"Tudor Revival","criteria":[],"status_note":"Described as in excellent condition with few alterations since construction; used as a conference center by Northeastern University.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:04.125384-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/34/7958/63795834/content/electronic-records/rg-079/NPS_MA/97000880.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/97000880/e447b2fa62-800.webp","url_1600":"https://nationalhistoricalregister.com/media/97000880/e447b2fa62-1600.webp","licence":"CC BY-SA 4.0","author":"User:Magicpiano","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:WestonMA_HendersonHouse.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:WestonMA_HendersonHouse.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63795834","wikipedia":"https://en.wikipedia.org/wiki/Henderson_House_(Weston,_Massachusetts)","wikidata":"https://www.wikidata.org/wiki/Q5344810"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/middlesex-county/peirce-edward-house-henderson-house-of-northeastern-university-97000880/"}
