Each property has a semicircular arched doorway on the right-hand side, with panelled doors featuring pilaster jambs topped with cornices, the fanlight above the door of No. 49 being patterned. The ground floor windows are also semicircular arched and contain recessed sash windows. The upper floors contain recessed sash windows with glazing bars, set within flat, gauged arches. A plat band runs above the ground floor. The houses are finished with parapets and stone copings. Cast iron balconies with a geometric pattern are located across the first floor, and cast iron area railings are present to the front; those at No. 49 are topped with pineapple finials, while those at No. 51 have torch finials.
