A Georgian single-bay house of scribed roughcast walls and slate roof. In the lower storey is an inserted shop front framed by panelled pilasters, plain fascia and deep moulded cornice. A half-lit panelled door to the L has a plain overlight. In the middle and upper storeys the windows are offset to the R. They comprise a 12-pane hornless sash window in the first floor, and a similar 9-pane window in the upper storey.

A long gabled rear wing is roughcast with an end stack. In its 2-window S elevation facing the passage through No 16a are some original windows, namely 9-pane hornless sashes in the upper storey and a 12-pane sash window middle R. Late C19 2-pane sashes in earlier openings are middle and lower L, while the doorway lower R has a replaced door and plain overlight. A lower flat-roofed 2-storey projection further behind is L-shaped and provides a link to 9-11 Castle Ditch.
