Constructed of snecked and textured pink and red local sandstone with paler freestone dressings under green slate roofs. Detail includes stepped and raked angle buttresses, high moulded plinth, continuous hoodmoulds to windows, raised copings to gables and crucifix finials; the windows are mainly lancets with moulded stone dressings, containing small-pane leaded glazing.

Nave clerestorey is 5-bay with pairs of small lancets (single to R, adjacent to bellcote). Below, N aisle has 3 larger lancets with nook shafts and foliated capitals, separated by angle buttresses; smaller window to L; to far L eaves project down over a pointed-arched doorway. Similar arrangement of windows to S aisle and clerestorey, the 4-window aisle without nook shafts.
