The original builder is unknown.","why_significant":"The nomination presents it as a distinguished, largely intact example of settlement-period domestic architecture on Long Island, with heavy hewn timber framing, a center chimney with bake oven, and original wrought-iron hardware. It is also the only surviving recognizable eighteenth-century residence near Centerport and records the expansion of settlement along the north coast of central Long Island.","narrative":"Built around 1730, this saltbox farmhouse at the edge of Centerport on Long Island's north shore is a one-and-one-half story timber-frame building with a one-story wing added in stages during the eighteenth century. Its post-and-beam frame, hand-made brick center chimney with bake oven, early batten doors, Suffolk-type latches and a split Dutch door with wrought-iron hinges survive, while the windows, front door and exterior shakes are later replacements. The original builder is unknown. The Suydam family, subsistence farmers who shipped surplus produce to New York City by schooner, appear to have arrived in the 1760s and acquired the house within about two decades. Family members owned it until 1954. The house is listed because it is a well-preserved example of early Long Island construction and the only recognizable eighteenth-century residence left near Centerport. Today the Greenlawn-Centerport Historical Association owns it and plans a headquarters and museum there.","period_of_significance":"Eighteenth century (stated as the house's eighteenth-century period of significance; no specific date range given)","architect_builder":"Unknown (architect and builder both listed as unknown)","architectural_style":"New England style saltbox; vernacular Long Island settlement-period farmhouse, with a Greek Revival stoop","criteria":[],"status_note":"Condition marked fair; used as a residence, and owned by the Greenlawn-Centerport Historical Association, which plans to use it as headquarters and museum. Two non-contributing outbuildings (shed and garage) are in poor condition.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:44.641739-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/88002135.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/88002135/95bf6a7baa-800.webp","url_1600":"https://nationalhistoricalregister.com/media/88002135/95bf6a7baa-1600.webp","licence":"Public domain","author":"Unknown authorUnknown author","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Suydam_House_Centerport_Suffolk_County_New_York.jpg\" rel=\"noopener\">Unknown authorUnknown author</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Suydam_House_Centerport_Suffolk_County_New_York.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75314947","wikipedia":"https://en.wikipedia.org/wiki/Suydam_House","wikidata":"https://www.wikidata.org/wiki/Q7650635"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/suffolk-county/suydam-house-88002135/"}
