18 Church Street, Ballynahinch, Co. Down, BT24 8AF

Two storey terrace shop, now vacant, probably originally a dwelling house dating from around 1840. The building is set on the slope of Church Street to the south of Ballynahinch town centre, with its front façade facing west.

The ground floor front elevation features central double doors with vertical timber sheeting and a rectangular fanlight, flanked by simple timber pilasters. To the left is a large shop window, now boarded over, also framed with timber pilasters. To the right is a narrower window opening, also now boarded over. The first floor has two widely spaced windows, each with a sash frame without astragals. A small portion of the north gable is exposed where it rises slightly above the roofline of the neighbouring building (No. 16). The south gable is obscured by the gable of No. 20, which rises above its apex.

The rear façade has a door opening to the right of centre at ground floor level, and a modern two-pane top-hung window to the centre of the first floor. The front elevation is finished in lined render, while the rear elevation is finished in roughcast. The gabled roof is finished in what appear to be asbestos slates. Two plain rendered chimney stacks are present, along with cast iron rainwater goods.

A two-storey pitched roof return was recently demolished, along with a single-storey lean-to extension.

Historical records show that when the first Ordnance Survey map was drawn up in 1833–34, much of what is now Church Street remained undeveloped. A house occupied this site at that time, belonging to Michael Nugent and recorded as an old, low, two-storey dwelling. The terrace as it appears today was constructed around 1840. The property was in the hands of James Flinn in 1863 and possibly Margaret Grant in 1899. The building functioned as a shop, probably from the early 1900s, but was a private dwelling when surveyed in 1974. The property was acquired by the current owner in 1977.
