1, 3 South Street, Duns

1 and 3 South Street in Duns is an early 19th-century building that incorporates earlier elements. It consists of two stories and an attic, featuring a seven-bay pair of houses with a unified shopfront that includes three shops at the ground level. The shopfronts are made of channeled ashlar with a single cornice, while the first floor is finished in dry-dash, and the sides and rear are harled. The shops have panelled and glazed doors, along with plate glass letterbox fanlights, and are flanked by large plate glass shop windows. There are piend-roofed timber dormers on the upper levels.

On the north elevation facing South Street, the broad left bay contains a shop at the ground level, a window on the first floor, and a dormer above. To the right, there are six bays with two shops at the ground level, flanking a flush-panelled door that has a decorative multi-pane fanlight leading to flat No 5. All bays have windows on the first floor, and there is a pair of dormers.

The south elevation at the rear features three bays set at a swept angle to the right. In the center, there is a flush-panelled door with a plate glass letterbox fanlight, accompanied by a narrow window to the left and a window on the first floor that lights the stair. There are small windows to the right and a blank section to the left. To the left, there are four irregular bays, with a tall stair window in the third bay from the right and two dormers, the left one being canted.

The gable ends are blank. The building has 12-pane timber sash and case windows, with 4-pane windows in the dormers. It is roofed with grey slates, features ashlar coped skews, and has scroll skewputts at the rear. The apex stacks are made of brick and rendered on the east side. The interior was not seen in 1993.
