It sits on a one-acre area within a larger horse farm parcel.","why_significant":"The house keeps its design, materials and workmanship from the late First Period and transitional frame, qualifying under Criterion C. Two sections are joined at attic level by double-dovetailed binding timbers, a very unusual way to connect two frame houses in Massachusetts. Although it was turned 90 degrees in the early 20th century, it remains largely on its original site.","narrative":"Built around 1720, the Col. John Osgood House at 547 Osgood Street in North Andover is a 2 1/2 story, five-bay clapboard house with a central chimney and an integral rear lean-to. It is made of two one-cell sections joined together, and only the right-hand section still shows late First Period details, such as an exposed quirk-beaded summer beam, chamfered plates and lamb's tongue stops. The two sections are tied together in the attic by two short double-dovetailed binding timbers, a very unusual method of joining houses in Massachusetts Bay. Early in the 20th century the house was turned from south to west to face a re-aligned road, and the chimney stack was probably rebuilt then. Because it was only rotated about 90 degrees on its original site, it keeps its sense of location. Its surviving design, materials and workmanship, together with the unusual framing, are the reasons it was listed. A late 19th century barn stands nearby on the horse farm.","period_of_significance":null,"architect_builder":null,"architectural_style":"Transitional First Period","criteria":["C"],"status_note":"Condition described as good; in present use as a residence (rental).","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:03.739563-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/30/7901/63790130/content/electronic-records/rg-079/NPS_MA/90000250.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/90000250/970e0143ab-800.webp","url_1600":"https://nationalhistoricalregister.com/media/90000250/970e0143ab-1600.webp","licence":"CC BY-SA 4.0","author":"User:Magicpiano","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:NorthAndoverMA_ColJohnOsgoodHouse.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:NorthAndoverMA_ColJohnOsgoodHouse.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63790130","wikipedia":"https://en.wikipedia.org/wiki/Col._John_Osgood_House","wikidata":"https://www.wikidata.org/wiki/Q5141773"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/essex-county/osgood-col-john-house-90000250/"}
