The reviewer recommended listing under Criterion C.","narrative":"Built in 1867 for Alpheus Mead, a local butcher, this house at 2200 Massachusetts Avenue in Cambridge is a center-entrance Mansard house typical of the mid-1860s. Original features include an entrance porch with quadrant struts, alternating gabled and segmental dormers, and a projecting bracketed cornice. Other details noted include modillons under the cornice, a double door, very large lintels, and a center arch with a pediment. Aluminum siding has been added over the years, but the original trim survives and the clapboarding likely remains underneath. The house was first residential and later put to commercial use, and it now holds professional offices. It is considered one of the best remaining houses of its type on the Avenue. Together with the Daniel Snow and R. H. Farwell Houses, it is one of only three residences in close proximity that show the style and scale of the homes that once lined this road, now largely replaced by commercial development and new construction.","period_of_significance":null,"architect_builder":null,"architectural_style":"Mansard","criteria":["C"],"status_note":"Present use is professional offices; aluminum siding has been added over the original clapboarding, and the original trim was retained.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:11:54.511177-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/72/7904/63790472/content/electronic-records/rg-079/NPS_MA/82001961.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/82001961/6f2831b30b-800.webp","url_1600":"https://nationalhistoricalregister.com/media/82001961/6f2831b30b-1600.webp","licence":"CC BY 3.0","author":"Tim Pierce","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Alpheus_Mead_House.jpg\" rel=\"noopener\">Tim Pierce</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:Alpheus_Mead_House.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63790472","wikipedia":"https://en.wikipedia.org/wiki/Alpheus_Mead_House","wikidata":"https://www.wikidata.org/wiki/Q4735307"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/middlesex-county/mead-alpheus-house-82001961/"}
