It is also notable for an attached two-bay carriage shed at the end of the side ell, described as unique in the multiple resource area. The form ties it to the farming settlement of Colonie after the decline of Van Rensselaer tenancy.","narrative":"This brick farmhouse at 140 Dunsbach Ferry Road in Colonie was built around 1840 in the Greek Revival style. It has a two-story main block with a side-hall plan, a three-bay gable-end facade, tooled stone lintels, and a recessed entrance with pilasters, sidelights and a transom. A one-and-one-half-story ell with large eyebrow windows extends from the main block and includes a kitchen and two carriage bays separated by a large cooking fireplace and chimney. The carriage shed is described as unique among the town's surveyed historic resources. Martin Dunsbach, a farmer, bought the land in 1837, and his family also operated the ferry across the Mohawk River. The farm remained intact until the 1950s, when a highway was built across the property. Today the house stands on about 2.5 acres without most of its farmland. Its significance rests on its rare brick construction and its place in Colonie's agricultural growth.","period_of_significance":null,"architect_builder":null,"architectural_style":"Greek Revival","criteria":[],"status_note":"Used as a residence; condition rated fair; the farmland was cut off when a highway was built across the property in the 1950s, leaving only a non-contributing garage and shed.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:44.944719-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/85002705.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75311996","wikipedia":"https://en.wikipedia.org/wiki/Martin_Dunsbach_House","wikidata":"https://www.wikidata.org/wiki/Q6775354"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/albany-county/dunsbach-martin-house-85002705/"}
