It stands three storeys high and features a three-window arrangement of 4-pane sash windows, with the upper windows being square. The centre of the façade has a six-panel door set within a lean-to rendered porch. There is also a lean-to on the left end wall that includes a door at the front.

The rear is made of whitewashed rubble with brick heads above the windows. The property has not been inspected.
