Unusual double gable front, the main chapel gable asymmetrically unbalanced by low gable over door, this last with short roof to valley and long low roof to left. Vestry projects left at right angles with large roughcast corniced stack in angle of two roofs.

Rubble plinth with ashlar chamfered top broken forward for 3 buttresses, a pair closely clasping the door, the right of these also the left buttress of the main chapel gable, echoed by one at right corner (one of a pair clasping corner). three foundation stones over plinth then very large 6-light free styled window with ashlar frame, mullions and tracery, leaded lights, and painted flush sill. Window is framed by thin buttress-piers rising from plinth level, with steep sloping tops under tiny gables. Tops frame a deep double-curved ashlar window head with gabled keystone, the curve shallower to window head than to upper edge. Window mullions are plain vertical except for centre one which flowers into cinquefoil-cusped heart tracery framed by two cusped mouchettes. Small triple vent in gable with louvres.

Doorway to left has tall narrow door with 3-light overlight, also double curved to ashlar head, in miniature of the big window head. Overlight has vertical mullions cusping to centre light and the shape is echoed in the head of the leaded-glazed panel in the door below. Under long roof-slope to left is a plain roundel, door in short return wall. Set-back vestry wing to left has taller roof, 2 narrow 12-pane fixed-light windows to side-wall right, arched large end-wall window with keystone to surround and 2 similar narrow windows to extreme left of rear wall, adjacent to rear gable of chapel, which has flanking buttresses with ramped tops, plain barred roundel window, and a little vent in gable as on main front.
