Outbuilding, Johnstone Parish Manse

The building is a house with associated outbuildings, constructed in several phases beginning in 1735. The main house was enlarged in 1795 and 1809 to create an L-shaped plan, featuring a three-bay south and west elevation and a stair turret in the re-entrant angle. The house is two storeys high and built of coursed rubble with ashlar margins, dressings, and rusticated quoins, all of which are whitewashed. Ground-floor openings on the south elevation were altered around 1840, incorporating enlarged windows and a recessed doorway with Doric columns in an antis, all with hoodmoulds. Margined first-floor windows are connected by an eaves band. The west elevation has a narrow, centrally-placed doorway with a modern doorcase. Sash windows with 12-pane glazing are found throughout. The building has a main cornice, end and axial stacks, and a roof that is gabled at the east and piended elsewhere, covered in graded slates. A tall, narrow, lean-to addition to the rear may have originally served as a privy, with an outbuilding adjoining it. A detached L-shaped range of outbuildings to the north was altered in 1878 by James Barbour.

The interior has been significantly altered, but retains a fine mid-18th century chimney piece, reportedly re-used from a house in Dumfries, within a ground floor room on the east side. Square ashlar gatepiers, also by James Barbour in 1878, stand to the west, topped with pyramidal caps and linked to an ashlar-coped garden wall.
