Schall, William and Caroline, House
Why it's listed
Built in 1835 of two-foot-thick fieldstone, the two-and-one-half story house at Green Lane was constructed for iron master William Schall and his wife Caroline. Its rear kitchen ell is part of the original 1835 construction, and the center-hall plan, six-over-six sash windows and Greek Revival moldings are largely original. Two entrances carry fan lights, and the interior retains fireplace mantels, original Dutch locks, and pine flooring. A stone wash house with a walk-in fireplace stands on the same parcel. The house was regarded as a well-preserved example of the Federal style in Montgomery County and as a reflection of the status of its first owner. Its interior woodwork and entrance detailing were considered of unusually high quality when compared with other local Federal houses.
Significance in brief: The nomination argues the house is a Federal-influenced vernacular example of Pennsylvania architecture with well-preserved interior woodwork, fan-lit entrances and an integral rear ell. It also says the house reflects the social standing of William Schall, an iron master, in the 19th century.

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.
