40 Newtown Street, Duns

40 Newtown Street in Duns is an 18th-century, end-of-terrace house that has undergone some later alterations. It is a two-storey building with three bays and is finished in harled render with cement margins.

The ground floor features four bays, with windows in the two left bays, a modern glazed door in the inner right bay, and a deep-set garage door in the right bay. The first floor has three windows at eaves level, along with a pair of small cast-iron rooflights.

The gable end is blank and supported by a pair of buttresses. The rear elevation was not visible as of 1993.

The house has four-pane timber sash and case windows, a crowstepped gable with a corbel skewputt, a rebuilt brick chimney stack, and a steeply-pitched roof that is slightly swept at the eaves, covered with grey slates.

Additionally, there is a tall rubble garden wall that extends the line of the gable to the rear.
