A unique blend of urban fashion and folk masonry, this side-hall town house was enlarged in 1796 (datestone) by County Register and Recorder Jeremiah Simpson, who incorporated one of Sunbury's first houses behind a front addition in an updated Federal style with a fanlight entrance, carved and dentiled cornice, and keystone lintels over the two-over-two windows. The masonry, however, is the work of an imaginative builder. Oversized fieldstones cut into circles and diamonds ornament the facades, forming a raised patterned stringcourse between the two stories with a decorative vertical band running down the center of the gable ends.
