Outhouse, 58-60 Kirk Street, Campbeltown

58-60 Kirk Street in Campbeltown is an early 19th-century, two-storey and attic, three-bay house featuring classical details. The front facing Kirk Street has squared and cherry-caulked rubble walls, while the sides and rear are roughcast with ashlar dressings. The building has a base course and a lintel course at the eaves, with raised margins around the windows and framing on the street elevation, and projecting cills.

On the northeast elevation facing Kirk Street, there is a pilastered doorpiece with an entablature at the center, a deep-set entrance door, a flanking window, and regular fenestration on the first floor. The entrance features a nine-panel, flush-beaded timber door with a decorative rectangular fanlight above.

The northwest side elevation has an entrance porch for No 58 at the first floor, with a vennel beneath. There is a concrete-covered access stair with a wrought-iron handrail built against No 54-56. The southeast side elevation is a blank gable end. The southwest elevation is three-storey with a single-storey projection at the center, a lean-to porch at the side, a tall stair window on the first floor above, and a low square window on the second floor (garret). The ground floor window in the right bay is slightly offset.

The windows throughout the house are timber sash and case, with plate glass on the rear elevation's third floor, four and two-pane at the dormers, four-pane at the porch, and twelve-pane elsewhere, except for the stair windows which have six and two-pane fixed lights. The roofs are covered in grey slate, with modern rooflights and timber piend-roofed slate-hung canted dormers on the outer bays of the northeast pitch. There are cast-iron gutters and downpipes, and roughcast stacks topped with circular cans and skew copes.

Inside, most of the original fittings remain, including a timber staircase, chimneypieces, cornices, panelled doors, and shutters. The inner entrance door is a two-panel design with a nine-pane glazed upper section and a rectangular light above.

The walls include a rubble dwarf wall with an ashlar cope facing Kirk Street, with curved ends flanking the entrance door and terminating to the north with an ashlar gatepier topped with a pyramidal cap and a surviving section of wrought-iron railing with arrow finials.

At the rear of the house, there is a monopitch rubble outhouse with vertically-boarded timber doors, and some wainscoting still survives inside.
