St Margaret's Roman Catholic Church, Sinclair Street, Clydebank

St Margaret's Roman Catholic Church, located on Sinclair Street in Clydebank, was designed by Gillespie, Kidd and Coia in 1972. The church has a roughly rectangular shape, featuring yellow facing brick walls on three sides and a small half-hexagonal apse. The roof is aluminium clad, with a space-frame construction in the center, and the glazing slopes from the wallheads to the central panel.

The front elevation includes a timber-framed glazed frontage topped with an aluminium-clad oversailing flat roof, which has an irregular polygonal plan. The front faces of the porch and main roofs display deep aluminium-panelled fascias, with the former inscribed with the name "SAINT MARGARETS" and a cross.

The side and rear elevations are constructed in plain brick stretcher bond, with courses of vertically-set stretches at intervals. Some of these vertical stretches have been omitted to provide cavity-wall ventilation.

Inside, the church is arranged for post-Vatican II liturgy from the outset. It features tiered wooden seating arranged in a fan shape around a stone-faced altar on a low dais, with a tabernacle positioned on a two-stage brick plinth at the rear. The sides and rear of the interior have multi-recessed brick panelling that reduces in height from the center, with diagonal pine panelling above.

Adjacent to the church is the presbytery, which is a two-storey structure with a flat roof and timber cladding. It is set in a bunker with vertical brick inner walls and grassed 'glacis' on the outer faces.
