Whallon, James, House
Also known as: Marquardt, George, House
Why it's listed
Built about 1816 on one of the highest points in the area, this two-story red brick house on Winton Road in Greenhills was constructed by James Whallon, who fired the bricks on the site. The west facade is laid in Flemish bond, with gauged brick over the windows and a doorway featuring sidelights and a delicate elliptical fanlight. Inside, carved elliptical motifs repeat on the mantels, and the entry hall keeps its original open-string stair with a cherry handrail. Whallon arrived in Ohio in 1800, farmed the land, served as Justice of the Peace and raised a devout Presbyterian family that produced several ministers. The house is regarded as a fine and uncommon local example of Federal architecture. The City of Greenhills bought it in 1958 and has used it for municipal offices, scouting and church services. Some alterations have occurred, but it retains its early character.
Significance in brief: The nomination argues the house is a fine, rare local example of Federal style architecture, notable for its delicate detailing and scale. It also represents the Whallon family, a pioneer family active in farming, religion and education whose substantial home reflects their success.

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.
