It was moved to its present site in 1866.","why_significant":"The house is a handsome example of a high, narrow Federal-style type that has not survived in large numbers in Cambridge. It also represents the homes of people of modest means in the early nineteenth century. The Frost family, whose ancestors acquired the surrounding land in the seventeenth and eighteenth centuries, drove the area's nineteenth-century development.","narrative":"Built in 1807 for Walter Frost, this wood-frame house at 10 Frost Street in Cambridge is a tall, narrow example of Federal-style design. William Saunders is named as the builder. The house originally stood on Massachusetts Avenue at the corner of Roseland Street, where it was the first in a line of mansions along the avenue. In 1866 it was moved to its present site to make way for the North Avenue Congregational Church. The Frost family shaped the nineteenth-century development of the surrounding neighborhood, on land their ancestors had acquired in the seventeenth and eighteenth centuries. Apart from a later Greek Revival porch, the house is described as unaltered. Its significance rests on its architecture and on the Frost family connection. It represents a house type that has not survived in large numbers in Cambridge, and it shows the kind of home occupied by people of modest means in the early nineteenth century. It remains in residential use.","period_of_significance":null,"architect_builder":"William Saunders, builder","architectural_style":"Federal","criteria":["A","C"],"status_note":"Present use is residential; unaltered except for a later Greek Revival porch.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:11:55.057009-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/14/7905/63790514/content/electronic-records/rg-079/NPS_MA/82001942.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/82001942/303364f0bf-800.webp","url_1600":"https://nationalhistoricalregister.com/media/82001942/303364f0bf-1600.webp","licence":"Public domain","author":"Daderot","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Walter_Frost_House,_Cambridge,_MA_-_IMG_4735.JPG\" rel=\"noopener\">Daderot</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Walter_Frost_House,_Cambridge,_MA_-_IMG_4735.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63790514","wikipedia":"https://en.wikipedia.org/wiki/Walter_Frost_House","wikidata":"https://www.wikidata.org/wiki/Q7964895"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/middlesex-county/frost-walter-house-82001942/"}
