It was built by the Fraser family in the 19th century on the site of the William Smith House.","why_significant":"The nomination calls the house a good example of vernacular Federal architecture common in the Hudson Valley in the late 18th and early 19th centuries. It argues that the site's link to local Revolutionary War history matters even more. The land belonged to William Smith, a Loyalist and noted historian, whose family's nearby house became known as the Treason House after the Arnold-Andre meeting.","narrative":"Set on a ridge off Route 9W in West Haverstraw, this two-story clapboard house looks out toward the Hudson River and Haverstraw Bay. It has a rectangular plan, a stone foundation, a hipped roof, five bays and end chimneys, with a symmetrical front and a full-length porch carried on four Doric columns. The entrance has a transom and sidelights with leaded elliptical designs. Inside are eight rooms, a central hall and fireplaces in every room. The Fraser family built it in the 19th century on the site of the William Smith House, which burned around 1808 or 1809. Smith was a Loyalist, a historian and a British informer during the Revolution. His family's land included the nearby Thomas Smith house, later called the Treason House after the meeting between Major John Andre and Benedict Arnold. The Hoyer family acquired the house in the early twentieth century, and it has remained a private home.","period_of_significance":"19th Century","architect_builder":null,"architectural_style":"Vernacular Federal","criteria":[],"status_note":"Described as in fair condition and altered, on its original site, and used as a private residence.
