St Dionis' Mission Hall

St Dionis' Mission Hall is a building constructed from red brick with stone bands and dressings, topped by a clay tile roof. Originally designed as a single tall space, it included a small narthex to the west and additional entrances to the south. The interior has since been horizontally subdivided to create upper and lower halls, along with toilets and a kitchen.

Architecturally, the hall showcases early French Gothic style, representing the robust variety of High Victorian ecclesiastical design. The south front facing St Dionis Road is nearly symmetrical, featuring two bays of paired lancets on either side of the grand main entrance. This entrance is adorned with stiff-leaf pilasters that support a pointed arch, topped with a crocketed gable and panels of incised ornament. Above the door, a tall two-light window with a ringed central shaft and a pierced quatrefoil head extends into a steep gabled half-dormer. To the left, there is a smaller door, also beneath a crocketed gable. The west front facing Parsons Green displays three stepped lancets with pierced quatrefoil heads, connected by a hood-mould and a flush stone band. Below, the lean-to narthex mirrors the south front, featuring a central two-light window and a gabled half-dormer.

Inside, the hall has a five-bay open layout (now subdivided) with wall-shafts attached to internal buttresses. These rise to stiff-leaf capitals that support the principal members of a scissor-truss roof. The external stone banding continues through the walls, visible both inside and out, although the interior brickwork has been painted. At the wall-head, there is a frieze of pierced quatrefoils with stencil decoration. At the east end, a broad stone arch encloses the sanctuary recess, flanked by colonettes with capitals that connect to the wall-shafts through a continuous band of stiff-leaf carving.
