The building is topped with a slate roof that has tiled cresting and three narrow rendered chimney stacks. The wide boarded eaves are supported by deep curved brackets. The windows are 12-pane sash windows, with architraves, and there are small pane tripartite windows at either end on the ground floor. An Ionic porch is located at the second bay, supported by iron columns and featuring a dentil cornice, deep boarded fascia, and panelled reveals. The rear of the building is cement rendered and has small pane sash windows. The left end gable has undulating bargeboards and is scribed rendered.
