Pirnmill Church, Pirnmill, Arran

Pirnmill Church, located in Pirnmill on the Isle of Arran, was built in 1910 and features a rectangular plan in a simple Arts-and-Crafts style, enhanced by a lower vestry wing that gives it an L-shape. The exterior is finished with dry dash harl and red ashlar sandstone dressings, topped with a slate roof. The front elevation includes a base course, ashlar-coped skews, and skew blocks.

The front elevation has a central two-leaf boarded door set within a chamfered doorcase, flanked by square-headed sidelights that feature pointed timber tracery. Above the door, there is a four-centred arch Y-traceried window with a hoodmould and label stops, along with a date panel on the gable.

On the left return elevation, there is a wallhead gable on the left with a stepped three-light window, and to the right, there are three bipartite windows. The right return elevation features three bipartite windows on the left, with the vestry gable advanced to the right, which has a stepped three-light window. There is also a further lower addition on the right return elevation.

The interior has not been seen. The property includes two pyramidal-capped ashlar gatepiers and rubble boundary walls.
