St Luke's is built of red brick, with dressings in Bath stone and roofs of blue slate, in the Early Gothic style. It was designed to accommodate over 300 persons, and is made up of a nave, chancel, south transept, vestry and south porch. The turret on the west gable contains one bell. Internal fittings include a stone font, oak lectern and reading desk. The benches and chairs are carved from deal. The church's floor was laid with concrete and wood, and the chancel paved with encaustic tiles from Minton, Hollands and Co.
