It has a two-story gambrel-roofed brick front block built c. 1766 and a rear stone wing, with 14 contributing farm buildings and structures.","why_significant":"The nomination argues the house is an important example of 18th century vernacular architecture in the Hudson Valley, blending New World Dutch and English building practices. The farm's outbuildings and landscape also document changing agricultural activity from the 18th to the 20th century.","narrative":"Locust Dale Farm, on Spook Rock Road southwest of Claverack hamlet, centers on a two-story brick house with a gambrel roof, built about 1766, and a rear stone wing of uncertain date. The farm covers roughly 150 acres of fields and woods and includes a large frame barn dating to about 1860, a silo, a corn crib, a privy, a smokehouse, a former summer kitchen and several 20th century sheds and garages. The brick block combines Dutch and English traditions. Cross-bond brickwork, decorative vlechtingen in the north gable, exposed ceiling beams, a jambless fireplace and a Dutch-style gambrel frame sit alongside a symmetrical five-bay facade, a center hall plan and load-bearing brick walls. A recent restoration removed later Italianate elements, replicated lost finishes and added a timber-frame wing at the rear. The property is valued for its architecture and for the way its buildings and landscape show how local farming changed from the 1700s into the 1900s.","period_of_significance":"c. 1766-c. 1940","architect_builder":null,"architectural_style":"Colonial: Georgian/Dutch Colonial; Early Republic: Federal","criteria":["A","C"],"status_note":"Used as a single dwelling; the house was recently restored from a dilapidated condition to an early 19th century appearance and a timber-frame addition was built at the rear.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:47.946632-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/09000861.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75317107","wikipedia":"https://en.wikipedia.org/wiki/Conyn_Van_Rensselaer_House","wikidata":"https://www.wikidata.org/wiki/Q5166786"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/columbia-county/van-rensselaer-conyn-house-09000861/"}
