Its altered chimney stack shows how First Period houses were adapted to Georgian taste, and the joining of two houses reflects the link between dwelling and workshop for cabinetmaker Joseph Hosmer. It also qualifies under Criterion D because hidden finishes and hearths may yield information.","narrative":"This house at 572 Main Street in Concord is a five-bay, two-and-a-half-story clapboarded dwelling with a central chimney and an eastern ell. Its core is a First Period timber frame, visible today mainly in chamfered summer beams with decorative stops and pips. Quarter-round chamfers in the east rooms suggest a date before 1700, while beveled chamfers in the west may be contemporary or slightly later. Around 1757, Major Joseph Hosmer, a cabinetmaker and farmer, probably added the northern rooms and joined a two-story gambrel-roofed house to the main block as an ell, perhaps to provide workshop space. The northern rooms have angled fireplaces, an example of an older plan adapted to Georgian taste. Georgian and Federal paneling, cupboards and a fine second-floor fireplace survive inside. The house is significant for its richly marked early frame, its evolution through the eighteenth century, and the potential for further research behind later sheathing and boxing.","period_of_significance":null,"architect_builder":"Major Joseph Hosmer (cabinetmaker) joined and enlarged the house, probably c. 1757; no architect is named.","architectural_style":"First Period","criteria":["C","D"],"status_note":"Residential use, condition described as good; 19th-century garage with rooms above, a former barn, stands on the property.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:03.67896-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/1/7904/63790401/content/electronic-records/rg-079/NPS_MA/90000170.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/90000170/6ce40e0e44-800.webp","url_1600":"https://nationalhistoricalregister.com/media/90000170/6ce40e0e44-1600.webp","licence":"CC BY 3.0","author":"John Phelan","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Joseph_Hosmer_House,_Concord_MA.jpg\" rel=\"noopener\">John Phelan</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:Joseph_Hosmer_House,_Concord_MA.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63790401","wikipedia":"https://en.wikipedia.org/wiki/Joseph_Hosmer_House","wikidata":"https://www.wikidata.org/wiki/Q6284081"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/middlesex-county/hosmer-joseph-house-90000170/"}
