Edward Clark (Lt. Governor 1859-1861; Governor 1861) purchased four lots, including this property, in 1856. This brick structure likely served as an outbuilding, and possibly as slave quarters, during the period Clark lived in the adjacent home from 1856-1867. The layout of the home is typical of slave quarters for the period and could have housed the ten slaves Clark owned. The vernacular, one-story load-bearing brick masonry building was constructed of double wythe, buff-colored Austin common brick. In the 1930s, original exterior features of the home were modified by owner Mamie Hatzfeld. Despite the changes, it is a rare surviving example of a pre-Civil War residential building.
