The building has a double-depth plan and is two storeys high with three bays.

The main entrance features a panelled door and fanlight within a Venetian Gothic surround, incorporating colonnettes and a heavy, bracketed hood.

Above, sash windows are found within chamfered stone architraves, complete with panelled aprons and decorative sills. The interior has not been inspected. The building is inscribed with the initials JN and the date 1864 over the entrance.
