Angle Farm
Also known as: Maplebrow
Why it's listed
Along a slope above Welsh Run in Montgomery Township, Franklin County, Pennsylvania, stands a farmhouse built in stages through the 19th century. Its oldest part is a log section with three bays on the north, apparently dating from the first quarter of the 1800s, to which a mid-19th-century addition of timber frame with brick nogging or log was joined on the south. The house has board and batten siding, a slate roof, and a main entrance with a nine-panel door and diamond-pane transom. A stone springhouse and a frame stable stand nearby. The house served for part of its history as the village post office, kept by Thomas Bowles, who owned it from 1840. Its interior woodwork, fireplaces and later Victorian alterations make it a readable record of successive building periods in the local vernacular tradition, and it is valued for that reason.
Significance in brief: The nomination argues the house is significant for its architecture as a representative of regional vernacular building traditions, with a log section and successive additions that show several periods of construction. It also cites social and humanitarian significance through its role in the village, including its use as the local post office for part of its history.

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.
