The focus of this district is a cluster of brick buildings around the intersection of Washington and East 22nd Streets on the north side of Dubuque.

Most of the houses are front or side gabled vernacular structures, and a few that are Italianate or Classical Revival. Couler Creek, which was located behind the houses on the east side of Washington Street, also affected the development of this area.
