The Gemmill-Faust House is a historic house at 321 St. Andrew's Terrace in West Helena, Arkansas. It is a two-story wood-frame structure with a brick-face exterior, built c. 1920. The house is an excellent local example of the Prairie School of design, with its broad spreading eaves, hip roof with hipped dormer, light-colored brick, and ribbon windows throughout. A period garage stands west of (behind) the main house.
