3-stage west tower (embraced by C15 westward extensions to nave aisles), spire, 5 bay aisled nave with north and south porches, 2 bay chancel with 2-bay north and south chapels and C19 north organ chamber.
At the west end of each aisle can be seen the original width of the C15 westward extension before Smith's remodelling.
the east bay is of 2 storeys (reflecting an earlier, probably C16, internal arrangement) with a square-headed mullion window of 2 lights to the ground floor and a square-headed window of 3 segmental-headed lights to the first floor.
South arcade: 3 west bays are early C13: pointed arches with paired rolls and a central quirk to the soffit on circular abaci and cylindrical piers on waterholding bases.
North arcade: 3 mid C13 west bays of pointed double-chamfered arches on similar abaci, cylindrical piers, and waterholding bases.
Late C13 chancel north chapel: 2 pointed, double-chamfered arches on quatrefoil pier: filleted attached shafts to responds.
Late C15 chancel south chapel: 2 pointed, double-hollow-chamfered arches on octagonal pier.
Set into the north wall of the south chapel is a small collection of Romanesque moulded and carved stones, including a sagittarius figure.
At the west end of the present nave, between the clearly inserted tower arch and arcade responds, can be seen a small area of C12 ashlar.
