The Donnelly House is a two-story wood-framed house, generally rectangular in plan and clad in textured yellow-buff brick with a flat-topped red-tiled hipped roof. An arched recessed corner entry is framed in sandstone, as is a portion of the large chimney. Many interior features survive. Built in 1926, the house has been attributed to Dr. M. J. Bisco, a dentist, who built a number of houses in South Fort Worth in the 1920s and 1930s. It is similar to other designs by Bisco (see, for example, 2900 6th Avenue). The original owner was George A. Donnelly, president of the Eastland Oil Co. The house remained in the Donnelly family until 1978, and may be eligible for the National Register following an assessment of Donnelly’s importance in the oil industry. The Donnelly House was designated Demolition Delay in 1995.
