Tonderghie

Tonderghie is an earlier 19th-century planned farm steading, laid out around a central square courtyard. It is notable for retaining a nearly complete horse-powered threshing machine. The steading comprises four ranges of single-storey and lofted buildings, constructed with rubble walls and polished red sandstone dressings to the main east front. The south and west ranges are roofless and are now derelict.

The east range has a symmetrical seven-bay facade. The taller, central bay features a near flat-arch pend with red sandstone voussoirs at ground level, and above it a pyramid-roofed dovecot with a round-arched opening facing east. The outer bays have depressed-arch cart entrances; the inner bays have two sash windows each, with 12-pane glazing. Two doors lead from the pend to stables: the right-hand door is for working horses, and the left-hand door provides access to three stalls for carriage horses, featuring a curved and shaped timber-lined roof and a hay chute trapdoor. Adjacent to the carriage horse stable is a harness room with a small fireplace. A hay loft extends the full length of the east range.

The north range is primarily occupied by a taller, two-storey threshing barn with a straw house attached to the west. The eastern portion of this range was originally a small byre or store. A circular horse engine house is projecting from the north face of the north range; it is rubble-built and has most of its original openings blocked with rubble. It has conical slate roofs. Internally, the upright shaft and harness shafts have been removed, but the gear train and drive shaft remain in situ. The drive shaft connects to a virtually complete roller feed threshing machine, with only the fanner unit missing. The straw house is located to the west, and the ground-floor access from it to the threshing barn was blocked in breeze block in 1988.

The south and west ranges were formerly byres, likely loose byres, and are now roofless but largely complete to wallhead. They are single-storey with depressed-arch openings. An opening in the west range was originally another pend, blocked in 1894. The footings of a drystone dyke, presumably enclosing the south part of the courtyard as a cattle court, are visible.
