St Patrick's Church Hall (aka Old School House), Victoria Street, Ballymoney, Co Antrim, BT53 6DW

St Patrick's Church Hall, also known as the Old School House, is a small single-storey gable-ended schoolhouse built between 1874 and 1876, designed by the architects Young & MacKenzie. It is constructed in dark basalt rubble with cream brick dressings and features pointed arch openings throughout. The building is symmetrical in its frontage, with twin 'sentry box' porches positioned at either end, flanking three tall windows that rise into gablets. The building now stands disused, though it was later adapted for use as a parish hall. It is located on the eastern side of Victoria Street in the centre of Ballymoney, within the grounds of St. Patrick's Church of Ireland.

The main body of the building is essentially rectangular in plan, with the porches projecting to the south. Attached to the north-east is a lower single-storey gabled return, to the west of which is a later, lower single-storey flat-roofed extension. A smaller lean-to extension with a rear porch is set to the west of this again.

The front elevation, which faces south, features the two projecting gabled porches, each with a pointed arch doorway fitted with a timber sheeted door. Between these porches are three tall pointed arch window openings that rise into gablets. The eastern elevation comprises the gable of the main hall and the flush east side of the return. Within the gable is a pair of pointed arch windows with an oculus above them. To the right of these, on the return, is another pointed-arch window that rises into a gablet. The return and larger rear extension abut a tall boundary wall to the north and have no openings on this side. A small yard lies to the eastern side at the rear, enclosed by the boundary wall to the north and a rubble wall with a segmental-headed doorway to the east; the timber sheeted door has partially collapsed. The western gable of the main section matches that to the east.

The roof is pitched and gabled with overhanging timber verges and fascias, with purlin ends expressed externally on the verges. It is covered in natural blue and black slate with matching fireclay copings. A tall red brick chimneystack rises from the ridge of the pitched roof of the return.

The walls of the main hall, return, and yard enclosure are constructed in basalt rubble with a battered rubble plinth. The walls to the flat-roofed extensions are finished in roughcast render. All window and door openings are dressed with cream or straw-coloured clay brick, with cut sandstone sills. Many windows have lost their frames; those that remain are predominantly timber with Y-tracery and hopper openers, though the flat-roofed extension contains a window with a steel frame. Rainwater goods have been replaced in uPVC, though sections are missing.

The western boundary of the site is enclosed by a rubble basalt wall with sandstone capping and wrought-iron railings. A pedestrian gate is flanked with square gate pillars with square caps, surmounted by a segmental-headed decorative wrought-iron arch. Wrought-iron 'hooped' railings segregate the playground in front of the building from the remainder of the church site. A kissing gate allows access through these railings to the church grounds and graveyard.
