Holy Trinity is a Commissioners' church designed by Lewis Vulliamy in Early English style.

[6] The church is constructed in punch-dressed sandstone ashlar, and has slate roofs with inserted skylight windows.

The plan consists of a four-bay nave without aisles, a two-bay chancel with a north chapel and a south vestry, and a west tower.

[5] Holy Trinity Church was designated as a Grade II listed building on 29 September 1977.

[7] Hartwell and Pevsner in the Buildings of England series comment that the church has a "sturdy quality" and "an impressive sheerness".
