Why it's listed

A brick house begun in 1738 on a high, commanding site in Chester County, Pennsylvania, built in the transitional Georgian style of the western Delaware Valley. Its four-bay south facade, Flemish bond brickwork, segmental window arches and transomed door are early features. The plan divides the house into four three-story brick corner rooms around a wide ground-level hall, and the interior, with its closed stair, baroque balusters, panelled doors and corner fireplaces, shows a plain, restrained finish. The builder, Joseph Pennock, was a farmer, maltster, county justice and member of the Provincial Assembly, and his family produced later notable figures, including Sarah Pennock, who married the botanist Humphrey Marshall. The house is regarded as one of the most ambitious early eighteenth-century houses in the county and is significant for its architecture and its place in colonial history. The Pennock family held it until 1960, when Stewart Huston deeded the house and fifty acres to the Primitive Hall Foundation.

Significance in brief: The nomination argues that the house is significant in architecture, for its environmental setting, and in colonial history. It is regarded as one of the most ambitious early eighteenth-century houses in Chester County. It was the homestead of the Pennock family, whose members included a county justice, a botanist's wife and an early woman ironmaster.

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.
