Crumlin Presbyterian Church, Main Street, Crumlin, Co Antrim

Crumlin Presbyterian Church is a Gothic Revival building comprising a rectangular nave with a gabled two-storey extension to the rear and a three-storey entrance tower to the front. The main entrance faces south.

The entrance elevation presents a symmetrical composition of the south gable with a central projecting tower, except for a circular stair turret set into the angle with the church to the right of the tower. The walls are smooth cement rendered, lined and blocked, with a moulded plinth and moulded projecting eaves course that continues as a string course around the tower. Similar string courses appear at two higher levels of the tower, with moulded coping to the south gable. Two-stage weathered buttresses flank each extremity of the south gable.

The tower is square with octagonal projections at the corners, corbelled out at the eaves course level of the church and at the rear corners of the tower, but rising from diagonal buttresses at the front corners. These continue upwards into corner pinnacles at the top of the tower, with crenellated parapets between them. The second floor of the tower has a central Gothic arched opening in each face, filled with wooden louvres and set under a Gothic arched label moulding. The first floor contains square windows in the centre of the front face with lozenge pattern cast iron tracery set in chamfered reveals; the other faces of the first floor are blank.

The main entrance is located in the centre of the ground floor of the tower, consisting of rectangular timber double doors, panelled, which are modern replacements for a ledged timber original. The doors are set in a Tudor arched surround inscribed 'MILLAR ARCHITECT' at the top (without bar to the As), surrounded by a label moulding surmounted by a framed stone panel inscribed 'Ecclesia Scotica'. Two granite steps combined with a concrete door step lead to the front door. The west side of the ground floor of the tower has a small rectangular window of lozenge pattern cast iron tracery in a chamfered reveal with a Tudor style drip moulding over, with perspex storm proofing affixed over the window.

The south gable of the church to the left of the tower features a tall Gothic arched lancet in a chamfered reveal with a cusped headed frame, glazing continued behind it, a deep splayed cill with coved underside, and a label moulding over. The circular stair turret in the angle between the tower and church to the right of the tower has walling as before, with a flat roof behind a blocking course. Facing south in the turret is a window similar to that in the south gable. A cast iron downpipe is positioned in the corner with the tower.

The west elevation of the church comprises a four-bay nave divided by two-stage weathered buttresses, with a recessed two-storey end bay at the same ridge height, also marked by a buttress, and a later two-storey extension set back to the left with a lower roofline. The main roof is covered in Bangor blue slates in regular courses with dark blue ridge tiles. Six small roof ventilators are positioned at intervals at mid-pitch. Cast iron gutters with circular cast iron downpipes are located in the second and fourth bays from the tower. Each nave bay has a Gothic arched lancet with two lights and a tracery spandrel, with detailing otherwise similar to the south gable window. The second, third, and fourth bays have circular cast iron ventilator grilles deep set in the wall below the cills, with a modern rectangular air vent at plinth level directly below. The set-back rear stair bay has two windows, one to each floor, consisting of rectangular timber fixed lights with top-hung vents, with a PVC gutter and PVC downpipe. The north gable of the set-back rear stair bay is blank above the later projecting gabled extension. The plinth of the set-back bay is not moulded.

The extension is roofed with slates in regular courses with a PVC gutter on a timber fascia and PVC downpipe and soil pipe. The walls are plastered, lined and blocked, with an unmoulded plinth. One window to the first floor on the west elevation is a rectangular timber fixed light with top-hung vent. The north gable of the extension is two-storey, with similar walling as before and timber barge boards. Two windows to each floor are Gothic arched varnished timber fixed lights of leading glazing with perspex mounted over the face. The east side of the extension is blank with a PVC gutter on a wooden fascia and PVC downpipe.

The east elevation of the nave is similar to the west side. The east elevation of the set-back bay is similar to the west side except for the absence of windows; instead it features a Gothic arched doorway, chamfered, with a modern replacement Gothic arched ledged wooden door with a modern handle, set in a chamfered wooden frame with three concrete steps. A cast iron gutter and downpipe are present.

The church stands facing the main road but set back within its own grounds comprising a grassed graveyard with a concrete path around the church. The front is approached by a modern brown concrete brick paved path leading from the front gateway and splaying to each extremity of the entrance front. No graveyard memorial stones are of any special architectural interest. The boundary to the front is formed by a gateway and screen walls between a sexton's house and a session room, both built within the church grounds and forming a semi-formal arrangement with the church itself. The boundary to the east is formed by a pebble-dashed wall with cement coping. The boundary to the west is formed by concrete post and wire fencing. The boundary to the rear is formed by a wall finished with wet dash of crushed stones and cement coping, containing a modern Gothic styled steel gate set within a tall Gothic shaped archway, rendered as the rear wall. A flight of concrete steps leads up from the road to the path at the rear of the church, lined by modern tubular steel handrails.

The front gateway and screen walls comprise a pair of square piers with roughcast panels with chamfered smooth rendered borders and shallow pyramidal smooth rendered caps surmounted by cylindrical metal lamp standards. Double gates of restrained scrolling designs are fitted. Curving forward from the piers are low screen walls of roughcast with broad concrete copings surmounted by plain modern iron railings, which return to each side to abut the adjoining gabled Session Room and Sexton's House.
