North Lodge And Entrance Arch, Duns Castle

North Lodge and Entrance Arch at Duns Castle is an early 19th-century Tudor lodge house that has undergone later alterations and additions. Originally rectangular in plan, it is now L-planned and is situated next to gatepiers and a Tudor-arched gateway that spans the road. The building features whinstone droved ashlar dressings, while later additions are harled. There is a whinstone wall flanking the ashlar gatepiers, which have an ashlar roll-topped moulding and a battered base course.

On the southeast elevation, the lodge has a four-bay design with square-planned gatepiers that include Gothick cusped panels and coping. The Tudor chamfered arch has roll-topped coping on the inner left. To the outer left, there is a whinstone wall with ashlar roll-topped coping, and to the inner right, a whinstone coped wall features a chamfered ashlar surround to a boarded studded door, which serves as a pedestrian entrance. The gabled wall of the lodge to the outer right has a tripartite window at ground level with a tabbed surround and a square plaque in the gablehead, along with kneelers to the gable. An ashlar wallhead stack is located to the outer left of the bay.

The southwest elevation has a three-bay layout with a screen wall to the outer left. A gabled ashlar porch is centrally located, featuring a Tudor-arched entrance with a shield above the apex. There are five steps leading to a boarded studded door, which also has a shield above the lintel. The flanking bays contain bipartite windows. The rubble and whinstone screen wall has ashlar roll-topped coping, and there is an ashlar-surrounded Tudor-arched boarded and studded door. A modern addition is set back behind the screen wall, with a modern door to the left and a modern window to the right.

The northeast elevation includes a half-piended modern addition at the center and a flat-roofed addition at the re-entrant angle. The lodge features four-lying-pane timber sash and case windows in each section of the bipartite and tripartite windows. The roof is covered with purple slate, and later additions are also slated. There is a brick gablehead stack on the northwest side. The interior was not seen in 1995.
