It is a flat-roofed, three-level International Style residence of steel and wood frame with stone and white-painted board siding.","why_significant":"The house was designed by Walter Gropius in association with Marcel Breuer. It is described as the second Gropius-designed house in the United States, after his own house in Lincoln, and his first American commission. It is also a distinctive adaptation of the International Style to New England's rockbound coast, using native stone and wood. It qualifies under Criterion C in Architecture at the local level.","narrative":"Perched about twenty feet from the Atlantic on Kimball's Point in Cohasset, this three-level house was built in 1938 as a summer home for Josephine Hagerty. Walter Gropius designed it with Marcel Breuer after her son John, a student in Gropius's Harvard class, suggested the commission. The flat-roofed box combines steel and wood framing, white-painted vertical board siding, rubble stone from the site, and lally columns that lift part of the house above high tides. Large glass walls face the ocean, and a two-story sun deck extends toward the water. It is regarded as Gropius's first American commission and his second house in the country. It also adapts International Style ideals to a New England shoreline through local stone and wood. Salt air, storms, and leaks led to repeated window and material replacements, most recently in 1992, though the original design has largely been preserved. Interior features include Breuer-designed bookshelves and chairs.","period_of_significance":"1938-1946","architect_builder":"Gropius, Walter; Breuer, Marcel","architectural_style":"International Style","criteria":["C"],"status_note":"Described as in excellent condition, with alterations largely limited to replacing deteriorated materials; it remains a single dwelling.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:04.516792-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/12/7962/63796212/content/electronic-records/rg-079/NPS_MA/97000529.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/97000529/9fbea155fe-800.webp","url_1600":"https://nationalhistoricalregister.com/media/97000529/9fbea155fe-1600.webp","licence":"CC BY-SA 3.0","author":"Wwoods","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Hagerty_House;2009-09-03.JPG\" rel=\"noopener\">Wwoods</a>, <a href=\"http://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:Hagerty_House;2009-09-03.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63796212","wikipedia":"https://en.wikipedia.org/wiki/Josephine_M._Hagerty_House","wikidata":"https://www.wikidata.org/wiki/Q6288409"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/norfolk-county/hagerty-josephine-m-house-97000529/"}
