South Lodge, Oxenfoord Castle

South Lodge, probably designed by William Burn around 1840, is a picturesque lodge with a T-plan layout and Tudor detailing. It forms part of a group including Oxenfoord Castle, Middle Lodge, and North Lodge. Located about a mile from the North Lodge, the lodge was described as a "beautiful little residence" in the early 20th century.

The lodge is predominantly single-storey with gabled elevations, constructed from stugged sandstone ashlar with chamfered arrises. It features tall, moulded, polygonal, and corniced stacks, and a porch in the re-entrant angle. The eastern elevation, the principal facade, has a basket-arched doorway within a gabled stone porch. To the left return is a narrow window, and the lodge adjoins the main house to the right return. The main house’s left side includes a recessed bay with a curved outshot chimney displaying sawtooth coping that rises into a pedestalled wallhead stack. A blank shield motif is set within a panelled pedestal. A broad gabled bay to the right of the porch features a corniced canted window and a blocking course. The western rear elevation exhibits a catslide projection in the re-entrant angle. A blank gable sits to the left, with a window on its return, alongside a later lean-to addition to the left return. The southern elevation presents a gabled end with a projecting tripartite window to the ground floor, and a corbelled wallhead displaying blind arrowslit detail above. A later, single-storey, harled lean-to addition on the northern elevation conceals the original elevation, with a modern timber door on the right return.

Most windows are timber sash and case, with 2-pane and 4-pane glazing, and some fixed diamond quarry panes to the side. The roof is gabled, covered in grey slate with zinc ridging and decorative timber barge boarding on each gable. Painted cast-iron rainwater goods are concealed. Additional decorative stacks, including one with a barley sugar design, are linked by a fluted bridge to the centre of the roof. A felted flat roof covers a rear extension featuring a harled stack.

The interior of the lodge was not inspected in 2000.

Stugged ashlar boundary walls with corniced coping run to the south. Three polygonal, ashlar gatepiers mark the driveway and pedestrian gate, which has studded neck detail, corniced caps, and armorial shield facetted blocks. Decorative cast-iron gates provide access to the driveway, while a single gate serves pedestrians. Semi-circular-coped rubble walls extend to the west and north, with a squat, corniced ashlar pier at the junction.

The architectural inspiration for the lodge diverges from the castle-like designs of the other lodges, drawing instead from Elizabethan architecture and exhibiting a stylistic connection to Cranstoun Riddel, the former residence of Lord Stair’s factor. The ornate chimneys are considered its most outstanding feature. The attribution to William Burn is likely due to his work on the estate from 1840 and the stylistic similarities to other buildings by him.
