St Andrew's Parish Church, 344 Muir Street, Motherwell

St Andrew's Parish Church, located at 344 Muir Street in Motherwell, was designed by Alexander Cullen in 1904. This rectangular-plan, asymmetrical gabled Gothic church features a bell tower with a caphouse at the northwest corner and a fleche on the nave. The exterior is constructed of red bull-faced, coursed squared and snecked sandstone with ashlar margins.

The southwest elevation, which is the principal facade, has three bays with a base course, cill height stringcourses, and an eaves course. The openings have chamfered reveals and stopped hoodmoulds. The gabled nave is central, showcasing three small lancets at the ground level and tall tripartite lancets at the gallery. The gablehead jetties out and includes an oculus, with blocking buttresses. There are stone steps leading to a pointed arch door in the center of the right bay, which has a shouldered stringcourse above a recessed panel and an inset tall lancet. To the left bay is a slightly advanced four-stage square-plan bell tower, which has stone steps leading to a pointed arch door with a slightly projecting gabled hood at the ground level, and a blind left return. The second stage features paired lancets, while the return has a single lancet. The third stage is blind, and the fourth stage has louvered bipartite lancets, a corbelled and crenellated parapet, and a crowstep gabled caphouse with a small arrowslit at the gablehead.

The northeast elevation is made of brick with red ashlar sandstone margins and has tripartite tall lancets in the center. It is a single storey with a flat roof, and a church hall adjoins the ground level. The northwest elevation consists of four bays with the bell tower on the outer right. It has set back buttresses between the bays, paired square windows at the ground level, and paired lancets at the gallery. The southeast elevation mirrors the northwest, but features a shouldered gabled bay on the outer left, with a tall, narrow lancet above a small square window that has a continuous cill course and a jettied gablehead.

Inside, the church has a plain galleried interior that is open to a hammerbeam roof. The windows are fitted with rectangular leaded glass. The roof is covered with grey slates and lead flashing, and the rainwater goods are made of cast iron.
