The first-floor windows are sash windows without glazing bars, while the ground-floor left has a three-light sash window with glazing bars and horns. The doorway is recessed and includes a rectangular traceried fanlight above a panelled door.
The gabled side elevation to the right has a flat-arched doorway flanked by pilasters and topped with a cornice on consoles. This doorway contains a four-panel door with a plain rectangular fanlight. The right side also features sash windows and an arched staircase window. The lower rear range has sash windows with glazing bars, including one triplet on the ground floor.
