Lancaster’s most important architect, C. Emlen Urban, designed this beautiful Colonial Revival townhouse in 1906 for Isaac H. Weaver, and wife Edith Bachman Weaver. Mr. Weaver later was president of Lancaster's Chamber of Commerce. He was a dealer in leaf tobacco.
The building contractor was Samuel H. Bally. The house features Flemish bond brickwork, a modillioned cornice, a rooftop balustrade, an entry portico with fluted columns, a water table, entry fanlight and sidelights, and an original three-bay wing to the south.
