Combining Federal proportions with Greek Revival details, Pratt's most impressive residence is a handsome, five-bay, two-story brick mansion, with a long, one-story rear ell. Its original pedimented two-story portico over the central bay has been replaced with a one-story porch extending the length of the facade. In the rear yard, facing Charles Street, is a small brick building with the legend “Veazey 1901” carved in a stone lintel over its entrance. Oscar A. Veazey, who purchased the property in 1880 and was appointed West Virginia's first state mine inspector in 1883, had his office here.
