[3] The church is built of stone with Welsh slate roofs.
The steeple has a tower with angle buttresses, two-light bell openings, a cornice, and a broach spire with four lucarnes.
The transepts are short and flat-roofed with parapets, and each contains an oculus window.
Inside, the crossing is of unusual construction, with four narrow arches, with heavy squinches in the corners supporting the tower.
The stone altar rail with iron gates, wooden pews and choir stalls, pulpit and font are all designed by Lamb, as are the north and west stained glass windows.
