The architect is unknown.","why_significant":"The building is significant as an example of the regional multi-family housing type known as the triple decker, built during growth in the town's eastern section. It reflects the severe Classical style common in the 1910s and 1920s and is one of the best preserved three-deckers in the Hamilton Street area. It is also tied to housing growth driven by the Hamilton Woolen Company.","narrative":"This triple-decker at 29-31 River Street in Southbridge was built between 1904 and 1925, based on Sanborn maps. It is a clapboard-clad, three-family house in a Colonial Revival Vernacular style, standing in a row of three-deckers across from the Harrington Cutlery factory. It is one of two similar houses side by side and one of a row of six built in different designs at about the same time on land that had stayed vacant into the twentieth century. Its plain Classical styling, common in the 1910s and 1920s, contrasts with the lacy porches of earlier three-deckers in the Flats. It is regarded as one of the best preserved three-deckers in the Hamilton Street area and has had no major alterations. The house reflects housing growth in Globe Village during the 1920s, when the Hamilton Woolen Company stayed active while many New England textile mills were closing. That company shut down after a strike in 1936.","period_of_significance":null,"architect_builder":null,"architectural_style":"Colonial Revival Vernacular","criteria":["A","C"],"status_note":"Condition described as good, with no major alterations and no outbuildings; in use as a 3-decker.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:01.087322-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/41/7934/63793441/content/electronic-records/rg-079/NPS_MA/89000575.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/89000575/759bd5d3d2-800.webp","url_1600":"https://nationalhistoricalregister.com/media/89000575/759bd5d3d2-1600.webp","licence":"CC BY-SA 4.0","author":"User:Magicpiano","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:SouthbridgeMA_29-31_RiverStreet.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:SouthbridgeMA_29-31_RiverStreet.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63793441","wikipedia":"https://en.wikipedia.org/wiki/Building_at_29%E2%80%9331_River_Street","wikidata":"https://www.wikidata.org/wiki/Q4986559"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/worcester-county/building-at-29-31-river-street-89000575/"}
