It is described as a now rare building type. It meets criterion C and retains integrity of location, design, setting, materials, workmanship, feeling and association.","narrative":"Lamont's Market occupies the southwest corner of Charles and Auburn Streets in Auburndale, a modest residential neighborhood in Newton. Built in 1910, it is a two-story, flat-roofed building whose slightly angled facade follows its corner lot. The walls are concrete block with cast stone trim, made by the Riverside Concrete Company, the building's first occupant. Rusticated block marks the basement level, smooth quoins emphasize the corners, and a wave-patterned frieze runs beneath the cornice. Two large display windows and a recessed entry are divided by buff brick piers. A period advertisement promoted the concrete construction as waterproof and fireproof. A second-floor apartment was added in 1928. Early occupants included a florist, a printer and, from 1913 to 1925, grocer F. A. Willis, followed by Malcom Lamont. The building is valued as a well-preserved example of a now rare building type made from an innovative material, and it still serves as a market.","period_of_significance":null,"architect_builder":null,"architectural_style":"Commercial","criteria":["C"],"status_note":"Condition good; the building continues in use as a market with an apartment, and no major alterations are recorded.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:05.090624-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/75/7906/63790675/content/electronic-records/rg-079/NPS_MA/90000029.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/90000029/0ae23cbb67-800.webp","url_1600":"https://nationalhistoricalregister.com/media/90000029/0ae23cbb67-1600.webp","licence":"CC BY-SA 4.0","author":"User:Magicpiano","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:NewtonMA_LamontsMarket.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:NewtonMA_LamontsMarket.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63790675","wikipedia":"https://en.wikipedia.org/wiki/Riverside_Concrete_Company-Lamont%27s_Market","wikidata":"https://www.wikidata.org/wiki/Q7338458"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/middlesex-county/riverside-concrete-company-lamonts-market-90000029/"}
