Walsh-Havemeyer House
Also known as: Plympton House
Why it's listed
Built around 1835 on a 2.06-acre parcel beside Quassaick Creek in New Windsor, this brick house was the residence of John H. Walsh, who oversaw the neighboring paper mill established by his father, Hugh Walsh. The house began as a one-and-one-half-story, hip-roofed Greek Revival building with brownstone trim and a three-sided porch of Grecian Doric columns. By the later 1850s the Havemeyer family lived there, and the main block and service wing were raised to full two stories. Inside, the center-passage, double-pile plan survives, along with black marble mantels, plaster ornament resembling the work of Minard Lafever, the original stair and the kitchen hearth. Pressed-tin ceilings were added around 1910. The porch columns have since been replaced by chamfered piers. The house is recognized as a locally significant, largely interpretable example of Greek Revival domestic architecture and as a reminder of the Walsh family's mill enterprise.
Significance in brief: The nomination argues the house is a locally significant, relatively intact example of 19th-century domestic design in the New Windsor area. Its original center-passage, double-pile plan and Greek Revival interior finishes largely survive, including marble mantels, plasterwork and the main stair. It is also an important link to the Walsh family's mill development along the Quassaick Creek corridor.

What listing means for this property
National Register listing is honorary for a privately owned home: it does not by itself restrict what an owner may do with their own money, and it does not require public access. Restrictions come from local landmark or historic-district ordinances, which are separate (how they differ).
Owner-occupied houses are not eligible for the 20% federal rehabilitation tax credit, which applies to income-producing buildings, but many states offer credits for homeowners. Listing also opens the door to preservation easements and to buying a plaque. Start with what listing means for homeowners, renovating a listed house and selling one.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
