Why it's listed

Built about 1747 by Joseph Gorgas, a miller, on land assembled by his father John Gorgas, this three and a half story house in Germantown is constructed of rubble stone with dressed stone on its front facade. Its gable roof carries brick end chimneys, and a one story kitchen wing of rubble stone extends from the rear. The house stands a full story taller than any other house built in the Germantown vicinity during the eighteenth century, and it is valued as an expression of the area's mid-eighteenth century domestic building. Its cove cornices and a coved pent eave between the second and third stories are notable features. Several mantelpieces, interior mouldings and some hardware survive inside. The name derives from legends that Johannes Kelpius built the house, and from its later association with the Ephrata community, whose members stayed there while traveling to Philadelphia on business.

Significance in brief: The nomination argues the house is notable for its size, being a full story taller than other eighteenth century houses in the Germantown vicinity, and as an interesting expression of mid-eighteenth century Germantown domestic architecture. Its heavy cove cornices and unique coved pent eave between the second and third stories are cited as distinctive features.

What listing means for this property

National Register listing is honorary: it recognises significance and does not restrict what a private owner may do without federal money or permits. It unlocks the 20% federal rehabilitation tax credit for income-producing buildings, state credits in many states, and Section 106 review when federal agencies are involved. See what listing means in practice.
