Downingtown Log House

Why it's listed
A round log house of one and a half stories, built circa 1700 on the banks of the Brandywine Creek area in Downingtown, is attributed to either Jeremiah Collett, Jr., or Joseph Hickman. Its measurements are 21 feet, 9 inches by 25 feet, with a slide-board opening on the south wall. Swedish features include the low doorway, horizontal planking on the gable ends, and the slide-board, while English influence appears in the shallow saddle-notched corners, larger windows, and a serpentine staircase. The Downing family acquired it in 1739 and added a Georgian mantel and interior partitions. The borough received the building in 1940 and restoration followed in 1947. It is regarded as the only surviving example of very early European settlement in central Chester County and the oldest documented structure in the vicinity. Its wider significance also rests on its local symbolic role for the borough.
Significance in brief: The nomination argues it is the only surviving example of very early European settlement in central Chester County and the oldest documented structure in the vicinity. It combines Swedish construction features with English Quaker adaptations, and it is traditionally the symbol associated with the Borough of Downingtown. Most of its interior and exterior is considered original construction.

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.
