Patterson, Samuel, House
Also known as: Kozar House
Why it's listed
Built in brick in New Alexandria, Pennsylvania, this five-bay farmhouse stands on a knoll above what was the Northern Pike, now U.S. Route 22. Local records suggest Samuel Patterson, a carpenter who became the largest contractor in the community, built it for his own household in 1846 on eighteen acres of a larger farm tract. Its Flemish-bond front and Georgian massing carry Greek Revival trim, including reeded columns, bullseye corner blocks and tiered mantel shelves, executed in a country manner. The interior remains largely intact, with original tongue-and-groove oak floors, hair plaster walls, period doors and hardware, and four original mantels. The upstairs east bedroom retains tiger-maple grain painting, a decorative survival that records earlier interior colors. The house is valued for its rarity as a surviving rural Greek Revival dwelling in the district and for its unusually complete woodwork.
Significance in brief: The house is presented as a rural adaptation of the Greek Revival style and one of the few such dwellings remaining in the New Alexandria area. Its largely intact interior, including original woodwork, mantels, doors and a tiger-maple grain painting, is cited as rare survival from its period. The document also notes Patterson's reputation as a renowned local builder.

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.
