Despite changes over the years and an unsympathetic commercial interior, Prentis Store is one of the best surviving pre-Revolutionary stores in the Chesapeake. Its exterior is unusually costly for a commercial building of its time, built of brick and finished with a modillion cornice and a pediment turned toward Duke of Gloucester Street. The original plan is perceptible in the fenestration. The front door gave public access to a sizable salesroom with shelves running the length of the side walls. A rear door led to stairs and a small office lighted with side windows and heated with a small fireplace. Storage and perhaps workers' sleeping space in the attic was lighted by narrow dormers.
