Gregg, Joseph, House
Why it's listed
Built about 1737 by Joseph Gregg on a rise in rolling farmland south of Kennett Square, this three-bay, symmetrical brick house has a stone foundation, an end-gable roof and Flemish-bond front walls with glazed headers. Its plan combines a symmetrical German-influenced facade with an English hall-and-parlor interior, and the nomination places it within the transition from Postmedieval to Georgian design. The Gregg family, descended from John Gregg, who had acquired the land in 1713, held the house and its 200 acres until 1915, when the land was sold. Kitchen and second-story additions were built around 1820 and 1860, and a 1916 frame addition was later removed. Restoration campaigns in the 1970s and 1980s retained most of the original woodwork, windows and hardware. The house is regarded as one of the few early examples in the region that retains its eighteenth-century interior with little alteration, and it is valued for showing how a prosperous farm family lived.
Significance in brief: The nomination argues the house is a nearly intact example of early eighteenth-century rural Southeast Pennsylvania vernacular Colonial architecture, combining German exterior symmetry with English plan features. It is described as one of a small number of such houses left relatively intact in the Chester and Delaware County region, and as a transitional form between Postmedieval and Georgian design. The Gregg family, who held the house for several generations, is also part of its historical context.

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.
