A former boarding house stands as an outbuilding on the one-acre site.","why_significant":"The nomination argues the house is a unique local example of Federalist architecture, notable for its high-quality design and fine granite ashlar construction. It is also associated with Richard Sayles, a local wool manufacturer who owned it after about 1852. It is argued to retain integrity of location, design, materials, setting and workmanship.","narrative":"Built around 1820-1825 at 80 Mendon Street in Uxbridge, this nearly square, two-story house has a hip roof, two interior chimneys and walls of hammered granite ashlar. The symmetrical south facade centers on a panelled door beneath a blocked semicircular light, framed by a projecting granite surround rising to a keystone. Stone blocks were matched for color and size, and the terraced site slopes to a granite retaining wall along Mendon Street. The original owner is unknown, though the design suggests a prominent mercantile or early manufacturing family. The house takes its name from Richard Sayles (1819-1887), a Rhode Island native who worked in Uxbridge woolen mills, supervised construction of the Central Woolen Mill, and later owned the Rivulet Mill. After his death the house was sold to the Calumet Woolen Company, which probably used it for workers' housing. It was listed for its Federalist design, its integrity, and its link to Sayles.","period_of_significance":null,"architect_builder":null,"architectural_style":"Federalist","criteria":["A","B","C"],"status_note":null,"vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:11:58.023249-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/85/7930/63793085/content/electronic-records/rg-079/NPS_MA/83004131.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/83004131/260345a43e-800.webp","url_1600":"https://nationalhistoricalregister.com/media/83004131/260345a43e-1600.webp","licence":"CC BY-SA 3.0","author":"Ksherin","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Richard_Sayles_House,_Uxbridge,_MA.jpg\" rel=\"noopener\">Ksherin</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:Richard_Sayles_House,_Uxbridge,_MA.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63793085","wikipedia":"https://en.wikipedia.org/wiki/Richard_Sayles_House","wikidata":"https://www.wikidata.org/wiki/Q7328905"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/worcester-county/sayles-richard-house-83004131/"}
