18 Langtongate & Gatepiers, Duns

16 Langtongate and its gatepiers in Duns are mid 19th century semi-detached Tudor houses, designed in a symmetrical pattern book style. They are two stories high and have two bays, set back from the road on rising ground. The front is constructed of stugged coursed ashlar with polished dressings, while the sides are harled with long and short ashlar dressings. The buildings feature a base course and chamfered arrises.

The south elevation has deep-set doors with Gothic panels and rectangular fanlights that include Gothic glazing. These doors are framed by stop-roll-moulded architraves. Above, there are bracketed balconettes with pierced balustrading and moulded coping. Between the doors on the ground floor are narrow hoodmoulded closet windows, and there are windows above the doors on the first floor. A single corbelled stack is located at the center, breaking the eaves, and features a pair of coped ashlar diamond flues with octagonal cans. The outer bays are advanced and have gabled roofs, with a piend-roofed canted window at ground level (the one for No 18 is cement-rendered) and a single hoodmoulded window on the first floor, which has a blank shield in the gablehead and an apex finial.

Both the east and west elevations are gabled, each with a window on every floor. The north elevation has advanced bays at the center, but the interior was not seen in 1993.

The windows are timber sash and case with 12 panes, although No 18 has uPVC replacements. The roofs are covered with grey slates, and there are brick apex stacks on the east and west sides, along with sawtooth ashlar coped skews and corbelled gablet skewputts.

The boundary walls, gatepiers, and railings include a low rubble front wall with saddleback ashlar coping. Each house has a pair of capped octagonal pedestrian gatepiers, with cast-iron spearhead railings and gates. There is a further pier that abuts 14 Langtongate to the east, and a tall coped rubble boundary wall to the west.
