St John's is constructed in
sandstone with
slate roofs. Its architectural style is
Early English. The plan consists of a five-
bay nave, a chancel, and a west tower. The tower is in three stages, the upper two stages being set back. At the corners are clasping
pilaster-straps, and the plain
parapet is further set back. The bottom stage contains an arched west doorway, above which is a pair of
lancet windows. Five steps lead up to the doorway, with a
wrought iron handrail on the left side. The handrail was designed by Brian Rourke in 1979 and is decorated with representations of the local industry. The middle stage of the tower contains small
chamfered windows on each side and a clock face on the west side. The top stage has
louvred, arched bell openings, and roundels containing
quatrefoils. The bays of the nave are separated by shallow
buttresses, and each bay contains a large lancet window. The east window consists of three equal lancets. The east window and the windows in the tower contain stained glass designed by George Wragge and date from the 1930s. ==External features==
