Geographically, the building is aligned on a northwest-southeast axis but this description treats this axis as the west-east
liturgical axis, e.g. the northwest elevation is regarded as the west for liturgical purposes. St John's Church stands prominently to the corner of Cunningham and Drayton Streets, Dalby and is set within extensive grounds. An elegant composition in the
Gothic revival idiom, the building is sheltered by a steeply pitched roof clad with fibrous cement shingles and the
buttresses and external walls are of brown facebrick embellished with white cement copings and mouldings.
Cruciform in plan, the
transept accommodates a clergy
vestry and a choir vestry and the west end a
baptistery flanked by entrance porches. The nave is lit by
lancet windows five of
stained glass and one of coloured glass to the north and two of stained glass and two of coloured glass to the south. Both vestries are lit by lancet windows of coloured glass. Circular lights are over the external entrances to the vestries and oval lights decorate the internal doorways from these spaces the light over the south entrance now without its coloured glass. Internally, these windows are embellished with plain
hood moulds. The east end accommodates the Mulholland memorial window, a fine stained glass window comprising three vertical arched panels crowned with three diamond-shaped lights depicting the
Transfiguration. The Geizel memorial window, depicting
St Cecilia, lights the baptistery. The
nave walls are plastered down to
dado height beneath which is red face brick. The ceiling is lined with battened fibrous cement sheeting with a narrow decorative panel running along the underside of the ridge. Large curved timber
brackets spring from oversized
corbels to support the roof beams. The
altar, with decorative timber panelling to the sides, stands on a raised platform within the
chancel which is lined to dado height with decorative cedar panelling. The church accommodates fine furniture including cedar
pews and
pulpit from the 1876 church, chairs,
kneelers and
lecterns. Other liturgical items include a silver communion plate, candlesticks,
sanctuary lamp and
processional cross. A wing accommodating more seating opens to the south from the sanctuary. This is part of the Frank Knight Memorial Hall, a rectangular brick extension to the south of the church. This extension is not of cultural heritage significance. The shrubs, trees, rectory, parish office and bell tower within the church grounds are not of cultural heritage significance. The property is bounded to Drayton and Cunningham streets by a low brick fence with decorative metal entrance gates. These elements are not of cultural heritage significance. == Heritage listing ==
