45-47 High Street, Ballynahinch, Co Down, BT24 8AB

45-47 High Street, Ballynahinch is a large two-storey terrace house dating from approximately the 1820s, situated on the west side of High Street in the centre of Ballynahinch. The asymmetrical front façade faces east.

The principal feature is a sturdy timber door, possibly original, with shallow panels. The doorway is encased with three-quarter Doric columns supporting an entablature, cornice and blocking course, and is topped with a semicircular fanlight displaying petal tracery. To the left of the doorway is a house window with simple moulded surround and modern frame. To the right stands a large modern shop front. The first floor contains four evenly spaced windows, similar in style to the ground floor left window but smaller, with segmental heads. The south gable is blank. All window frames are now modern examples.

To the rear is a large single-storey return, probably original, which has been extended in relatively recent times. This return contains various modern windows and a modern door. A window with modern frame appears on the ground floor of the main house façade to the right of the return, with three similar windows to the first floor and two stairwell windows set at intermediate levels.

The front façade is finished in painted lined render, while the rear and gable are rendered in unpainted cement rough cast. The gabled roof is covered in artificial slate (both asbestos and asbestos-free), with three Velux windows to front and three to rear. A single rendered chimney stack stands at the south end.

The site has held buildings since at least the mid-18th century. The present house, probably newly built around 1820, matches the dimensions of a property recorded in the valuation of approximately 1836-38, when it served as the manse for Ballynahinch Unitarian (Non-subscribing Presbyterian) Church and was the home of Reverend William Crozier. After Crozier's death around 1867, a shop was inserted into the building—documentary and photographic evidence indicates this occurred before 1905. By the 1930s it operated as a grocer's run by Mr Thompson, with the house occupied by families including the Fultons and a Mrs Hart, who remained until sometime in the 1940s. The house may also have contained a doctor's surgery at some point. In the late 1940s the property served as Ballynahinch Technical College. The current owner acquired it in 1955. The building sustained damage from two nearby explosions in the 1970s; following the first in 1973, the front window frames were replaced with modern versions.
