This finely-scaled Federal style frame house is of a central hall plan; its exterior displays a symmetrical five-bay facade with hip roof and twin chimneys. A denticulated main cornice and delicate window caps add decorative interest to the facade, while attention is drawn to the entrance by a columned porch with cove ceiling. The possibility exists that the northeast kitchen wing is Samuel Plumb's own dwelling house, built around 1740, and relegated to a minor role as an attached dependency by the subsequent construction of James Plumb's "Mansion House".
