Lodge, Johnstounburn House

Dated 1841, this is a single-story gate lodge with a rectangular plan, and modern additions at the rear. It is constructed of red sandstone rubble with stugged and droved grey ashlar dressings.

The south elevation is three bays and symmetrical. A slightly advanced gabled bay is centrally positioned, featuring a doorway with a decoratively bracketed cornice and chamfered reveals. The lintel above the door is inscribed "A 18TakThocht. BigNocht41 B," along with a two-pane fanlight. Pointed arrow slit windows flank the doorway, with a blind arrow slit at the apex of the gable. Bipartite and mullioned windows are found in the outer bays.

The east and west (gable) elevations have a window at the centre and a blind arrow slit at the apex. The bipartite sash and case windows have a lying-pane glazing pattern, while the glazing on other windows varies. The roof is covered in purple slates and features crowsteps. Two pairs of coped ashlar diamond ridge stacks are present.

The entrance arch, quadrant walls, and retaining walls are likely from the same period, 1841, and are constructed of red sandstone rubble with stugged ashlar dressings. The central archway is segmental and in a mannered Dutch style, with an ashlar coped gable incorporating a shield panel facing the road. Ashlar-coped quadrants flank the arch, leading to pedestrian gateways within the main, coped retaining walls. These have mannered Dutch-style gables with blind arrow slits above the entrances.

The lodge was commissioned by Archibald Broun, who likely commissioned the entrance arch in 1841, possibly from William Burn. Broun was likely the patron of the coach house, which is listed separately. According to local accounts, he moved to Chesterhill House, opposite, towards the end of his life, having spent his funds at Johnstounburn; the lintel inscription is believed to advise visitors to not build anything.
