Kilbarchan West Parish Church

Kilbarchan West Parish Church was built between 1899 and 1901, designed by architect William H. Howie. The church is constructed of red sandstone and snecked bull-nosed rubble, with ashlar detailing, and features a Gothic style with an irregular plan. It has a Scotch slate roof and ogee gutters.

On the Church Street elevation, the church has a buttressed gable that is narrower than the main body of the building, topped with a gablet cope and a cross finial. A tall five-light window with plain tracery and a cinquefoil head is present, although the lower part of the window is blind. A cill course and hoodmould step down to the buttresses. At ground level, there are three bipartite windows with cusped heads and a deep base course. To the left, there is a set-back gabled porch with a double doorway accessed by railed steps, featuring an arched head with a central vesica and a blind ocular. Further left is an octagonal stair tower with a lancet window on the front face, a hoodmould, and a pyramidal roof topped with a wrought-iron finial. To the right, there is a small door and another octagonal stair tower similar to the one on the left, but with a small window at ground level. A transept is located beyond.

The south elevation features the main body of the church with three lancet windows that have Y tracery, separated by buttresses. To the far left is a semi-octagonal apse. On the right side, there is a two-storey gabled vestry block with a stair tower at the extreme right. The vestry has a low door on the right at ground level and a bipartite window to the left, both with louvered heads. There are two bipartite windows at the first floor with stained and leaded glass. A chimney is located on the left gable, along with a later boiler-house chimney in the re-entrant.

The east elevation shows the gable of the main range, which has a plain cope and gableted skewputs. The semi-octagonal apse features a simple traceried three-light central window, flanked by lancets.

On the north elevation, there is a three-bay transept with three-light lancet windows at the first floor and tripartite windows at ground level, the latter having segment heads and relieving arches. A stair tower is positioned to the left of the transept, with a lancet window on the north face. In the body of the church, there are two small Y-traceried windows with curved cills, and a doorway in the re-entrant has a moulded segment head.
