Fullarton Parish Church, Church Street, Irvine

Fullarton Parish Church, built in 1838, is an aisleless rectangular plan church featuring Tudor Gothic details. It has a corbelled gablehead belfry and corner pinnacles at the southeast. The exterior is constructed of squared and snecked rubble stone with ashlar dressings, a base course, quoins, square leaded openings, battered cills, and hoodmoulds. The church has deeply chamfered arrises and a harled northeast elevation.

On the southeast elevation, there is a central entrance door with a rectangular fanlight above it, flanked by tall windows and a 4-light lancet set in a rectangular window above. The northeast elevation features a 4-bay nave with three tall windows and a doorway to the left, which has a simplified shield panel above. The southwest elevation mirrors the northeast with a doorway to the right. The northwest elevation has two tall windows and a shield panel in the center of the gable, while a later hall extension obscures the lower part of this elevation.

The interior was not seen in 1997. The southeast elevation has multi-pane glazing, while the nave has later 6-pane glazing and stained glass on the northwest side. The church features grey slate roofing, deep coped skews, squared ashlar skewputts, and two polygonal ashlar stacks behind the gablehead to the northwest.

Adjacent to the church is a single-storey church hall that extends to the west, which is not included in the listing. The former schoolhouse is also a single-storey, 5-bay rectangular plan building made of squared and snecked rubble stone, with square-headed windows and hoodmoulds.

The northeast (principal) elevation of the schoolhouse has bays grouped as 1-1-3, with an entrance in the second bay from the left featuring an ashlar porch and a pointed arch doorway, topped with a small gable that has skews and a ball finial. The southwest elevation has five bays of windows symmetrical with the northeast elevation, but a flat roof addition obscures three bays to the right. The southeast elevation showcases a 3-bay gable end with an armorial panel in the center. The northwest elevation is obscured by a low rubble built lean-to, with one surviving window to the right.

The schoolhouse features 18-pane timber sash and case windows, a recent machine tile roof, coped skews, skewputts, and an ashlar gablehead stack to the northwest, along with a later brick stack to the southeast. The interior of the schoolhouse was also not seen in 1997. The flat roof addition to the southwest is not included in the listing.
