The western three bays date to about 1700, with an eastern section added in the mid- to late 1700s.","why_significant":"The nomination argues the house is an intact, representative example of settlement-period residential building in Syosset and Oyster Bay. It is also tied to the Schenck family, among the earliest Dutch settlers of Long Island. Its mix of English timber framing and Dutch features reflects the local blending of the two building traditions. A careful late-1940s restoration after abandonment and vandalism preserved it.","narrative":"Set on about three acres off Convent Road in Syosset, this 1½-story wood-shingled farmhouse began around 1700 as a three-bay western section, with an eastern addition made in the mid- to late 1700s. It has a center-hall plan, large chimneys at each end, and an exposed fieldstone panel on the west wall. The house reflects the meeting of English and Dutch building traditions on central Long Island. Its framing follows English practice, while the stone end panel and other details recall Dutch influence. It is also associated with the Schenck family, early Dutch settlers who farmed a 57-acre tract here. After roughly a decade of abandonment and vandalism, a mid-1940s owner restored the house, replicating lost windows, doors and hardware and adding dormers in an Old Dutch style. A relocated late-19th century barn stands nearby but is counted as non-contributing. The house is considered an increasingly rare early 18th century survivor.","period_of_significance":"c1700 - 1948","architect_builder":"unknown","architectural_style":"Post Medieval English; Dutch Colonial","criteria":["A","C"],"status_note":"Used as a single-family dwelling; restored in the late 1940s after a period of abandonment and vandalism.
