Baptist Church & Church Hall, Windmillhill Street, Motherwell

The Baptist Church and Church Hall on Windmillhill Street in Motherwell were designed by Alexander Cullen and completed in 1895 and 1909, respectively. The church features a rectangular plan and is styled like a Lombard basilica, with a tripartite pedimented facade made of ashlar red sandstone and harled sides. It has a base course and eaves course, with semicircular arched openings and chamfered reveals.

The southwest entrance elevation has a slightly advanced central pedimented bay with a door at the center, topped by a cavetto hoodmould. Above the door is a tripartite window set within a semicircular recessed arch that breaks the pediment, flanked by Corinthian columns and plain giant order pilasters. The flanking bays have regular fenestration, and the eaves course features a Lombard frieze and projecting cornice.

The northeast rear elevation is a gable end, which is obscured by the adjoining church hall. The southeast side elevation has five bays with regular fenestration, except for a pedimented canted bay with a piended roof on the outer left and tall gallery windows. The outer right bay is blocked and obscured by the hall's forestairs. The northwest side elevation mirrors the southeast, but features an oculus in the tympanum of the pedimented bay.

Inside, the church has an open plan with plain whitewashed walls and square-pane leaded windows. The roof is covered with grey slates and pantile ridges, and there are cavetto moulded cast-iron rainwater gutters.

The Church Hall, designed by John Wilson in 1909, is a two-storey, rectangular-plan building with a gabled roof made of harled sandstone. The principal southwest elevation has forestairs to the far right leading to a first-floor entrance, which features a two-leaf door with a semicircular fanlight set within a gabled red ashlar sandstone porch. The bays to the left are obscured by the adjoining chancel. The northeast rear elevation has a blind, flat-roofed modern addition at ground level. The southeast side elevation has a gable end with a tripartite window in the center, inscribed by a semicircular hoodmould, flanked by windows, and a large blocked Venetian window on the second storey. The northwest side elevation is obscured by modern additions. The hall is also topped with grey slates, lead flashing, and coped skews.
