Cluntagh House, 68 Ballytrim Road, Cluntagh, Crossgar, Co Down, BT30 9LD

Cluntagh House is a substantial two-storey farmers' house of approximately 1845–1850, with a gabled return to the rear. The house is set on the south side of Killyleagh Road at Cluntagh Crossroads, about two miles east of Crossgar. The front façade faces west and is symmetrical in composition.

The ground floor features a central panelled timber doorway with a radial elliptical fanlight and single-pane arch-headed sidelights with panelled aprons. The doorway is surrounded by an unusual rendered gabled surround, which marks where a former, probably Edwardian, hipped roof conservatory-like porch was removed. To the left of the doorway is a window with a frame that appears to be a sash with Georgian panes (6/6), but is actually a modern top-hung model. This window has a smooth render surround with label moulding. The same style of replica sash frames is used throughout the house, and most are entirely convincing until examined closely. To the right of the doorway is a similar window. The first floor has three slightly shorter windows with moulded keystones but no label moulding.

The north elevation comprises the north face of the low two-storey gabled return on the left and the north façade of the main house section. The return's north face has two ground-floor windows and two first-floor windows in line, all with replica sash frames. First-floor windows here are smaller (6/3 panes) and feature smooth render surrounds with moulded keystones. The north façade of the main house has two windows on each floor with moulded keystones to those on the first floor but no label moulding.

The south façade of the main section repeats the north arrangement, except the first floor lacks a window on the right side; instead, a small window-like recess with label moulding and similar detailing occupies this space. A gabled outbuilding stands very close to this façade, with a short wall and gate spanning between the house and building.

The rear elevation of the main house features a broad window with a recent four-light frame on the ground floor to the left. Roughly at the centre of the first floor is a window matching the front style but without surround or moulding. To the right extends the return, whose east-facing gable is blank. To the south, the return has been extended in lean-to fashion with two casement windows and a partly glazed door.

The main façade is finished in early twentieth-century-style dry dash with in-and-out smooth render quoins, eaves course, and base. The rear façade and lean-to are lined rendered and painted. The hipped roof of the main house features two tall, centrally located yellow brick chimney stacks with dentilled corbelling, set broadside forward. These stacks are probably replacements of circa 1880–1900. The gable of the return carries a smaller stack in similar style. The entire roof is covered in natural slate with PVC rainwater goods.

To the south of the house is a large two-storey gabled outbuilding in rubble and render with modern windows to its west face. Immediately to the east is a larger gabled outbuilding in rubble with a series of arched openings supported on cast-iron columns in colonnade fashion to the ground floor on the north side. On the first floor are three small windows with replica sash-like frames and a timber-sheeted loft door. This outbuilding has been greatly renovated in recent times, including reconstruction of the archways and roof. To the east of the house is a longer but lower two-storey outbuilding, now largely rendered with modern-style window frames to its small openings. This outbuilding may contain the fabric of a pre-1834 dwelling.
