Why it's listed

Built beginning in 1854 on a 312-acre tract in the Great Valley, this two-story stuccoed stone mansion in the Cottage Style was begun by Hewson Cox, who died in 1859. The house has a cross-shaped core, steeply pitched gables with lancet windows, and diamond-paned windows, and it was regarded as a mansion from the start. In 1904 Clarence Sears Kates bought the estate and commissioned Milton Medary to renovate it, adding a Tudor-style library and music room with a balcony for an organ, stained glass, and gothic vaults. The original core was left largely intact. The house is significant as an early example of Gothic Revival design in the region, shaped by Downing's published designs. Kates later helped establish Church Farm School, a farm and trade school for orphaned boys, and the property was bought by the school in the 1950s.

Significance in brief: The nomination argues the house is an excellent example of mid-nineteenth century Gothic Revival domestic design, inspired by the designs of Andrew Jackson Downing, and an early introduction of Gothic Revival elements into the Great Valley. Its 1904 alterations, in the Tudor or Baronial Manor style, are described as not obscuring the original design.

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.
