North Lodge including gates, Winton Castle

North Lodge, including gates, is an early 19th century structure featuring twin castellated towers that were linked by Gilbert Ogilvy around 1925. The building is constructed from stugged ashlar sandstone and includes chamfered reveals, a base course, and hoodmoulds above the pedestrian doors and lancet windows. The towers have corbelled and gablet-coped crenellated parapets. Each octagonal tower is two storeys high and divided by a string course, with a tall window at ground level facing the roadside and a smaller window on the first floor, mirroring this arrangement on the drive side.

A passage link made of ashlar connects the towers, featuring a wide pointed-arch gateway flanked by pedestrian gateways, each topped with a blank shield. The parapet is raised above the drive arch. Attached to one of the octagonal towers is a square-plan, squat single-storey tower with angle buttresses. This tower has a hoodmoulded doorway that is partly obscured by a lean-to modern porch on the roadside and features a medallion plaque above the window on the drive side. There is also a late 19th century gabled addition to the east. The doorways to the towers are located under the passage link, adjacent to the gateways.

The gates are likely from the 17th century and consist of fine two-leaf wrought iron gates with an overthrow at the drive arch, along with possibly later gates at the pedestrian gateways.
