It is a small, isolated enclave neighborhood of 2- and 2+1⁄2-story masonry duplexes constructed about 1877 to house workers in the nearby Meadow Mill of the Woodberry Manufacturing Company. All but one of the eleven duplexes are constructed of brick, hence the four-acre enclave's traditional name; the other dwelling is built of stone. Two small two-story frame houses are also included in the district.
