The Roberts-Quay House is an historic, American home that is located in the Washington Square West neighborhood of Philadelphia, Pennsylvania. The original section was built circa 1850; it was then expanded in 1889, 1906, 1921, and 1928.
This historic residence was the home of Matthew Quay (1833–1904), a United States Senator from Pennsylvania. Its original section measures forty-seven feet by fifty-one feet, and is a four-story building with a brownstone face and sides of stucco, scored as brownstone. It has a basement, attic, and cupola and was designed in a Renaissance Revival style. The expansions to the north added one hundred feet to the depth of the building.[2]
