Description

The Old Post is a 1½-storey house with whitened pebble dashed walls and a steep slate roof. It features a small roughcast stack on the left and a larger roughcast stack on the right where the ridge line rises. The openings are offset to the left of centre. The central entrance has a replacement fielded-panel door set in a doorcase with a pediment, flanked by 12-pane hornless sash windows. Above, a central attic gable contains a small sash in a bullseye window, with 12-pane horizontal-sliding sash windows in raked dormers on either side. On the right gable end, there is a 16-pane hornless sash window in the lower storey and an attic casement window on the left side.

The rear of the house is rendered and features a central small-pane Gothic stair window, with an inserted glazed door to the right, below a gabled dormer that has a replacement casement window. On the left side, there is a 2½-storey rear wing, mostly with enlarged or replacement windows, which includes a 1-storey flat-roofed projection against the gable end.

The house's plan reflects early 19th-century alterations, with a central hall and a stair that has a quarter turn, featuring plain balusters and a turned newel. The rooms on the right and left both retain original stop-chamfered cross beams. In the right-hand room, the window reveal has a panelled cupboard door, likely providing access to a former posting box.
