Koehne-Poast Farm
Why it's listed
West of Germantown, Ohio, this farm centers on a two-story brick farmhouse built in 1853 in the Greek Revival style. The house has a square plan with a central hall and a three-bay facade. Its main feature is a recessed central doorway framed by pilasters, an unusual entablature and fluted Greek Doric columns in antis. Inside, a double-flight stair rises from the main hall, and a Victorian iron-front fireplace and the trim survive in excellent condition. Brick smokehouse and springhouse stand behind the house, and an antique bank barn with a fieldstone foundation sits in the hillside to the west. The nomination ranks the house as the best Greek Revival farmhouse in the greater Dayton area. It also notes two prominent owners: Jacob Koehne, who bought the land in 1839 and served Germantown Academy and the cemetery association, and Rev. Peter C. Prugh, a Reformed Church minister. John Poast bought the property in 1882.
Significance in brief: The nomination calls it an excellent example of an Ohio Greek Revival farmhouse, the best in the greater Dayton area. It is also tied to Jacob Koehne, a notable Germantown citizen who owned the land when the house was built, and to Rev. Peter C. Prugh, a Reformed Church minister who later owned it.

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.
