Ballykilbeg House, 22 Ballykilbeg Road, Ballykilbeg, Downpatrick, Co Down, BT30 8HL

Ballykilbeg House is a large, plain, cube-like two-storey gentleman's residence dating from around 1791, situated at the end of a short drive to the east of Ballykilbeg Road, approximately three miles south-west of Downpatrick. The building is graded B+.

The symmetrical front façade faces south. At the centre of the ground floor is a flat-roofed entrance porch added around 1994, which replaced an earlier Edwardian conservatory-like gabled example. The porch rests on splayed steps belonging to the original doorway and has a panelled door to the west and a sash window to the south with horizontal glazing bars (2 panes over 2). A smaller fixed light frame window sits on the east face of the porch. To the left and right of the porch are two further windows each, matching the porch window style. The first floor has five similar but slightly smaller windows, with the central window set in a shallow semicircular arch recess that originally extended to ground level but is now obscured by the porch. All windows have horizontal glazing bars unless stated otherwise.

The shorter west façade has two windows to the centre and right of the ground floor (matching the front arrangement) and three to the first floor. To the left of the ground floor is a modern partly glazed door with a simple hood, which does not appear to be an original opening. The east façade has a similar arrangement to the west, with three ground floor windows and blind window-like recesses to the first floor.

The rear façade is effectively three storeys, as a moat-like ditch reveals the basement level. At basement level, a small hipped-roof porch with a timber-sheeted door and three-pane fanlight sits centrally, its walls rubble-constructed with remains of harling. To the right is evidence that a square window has been blocked. The ground floor has four windows: the left window matches the front style; the central window retains Georgian 6/6 panes and sits in a shallow semicircular arched recess; to the right is a much smaller window with a modern frame, with a broad sill below suggesting it was originally larger; further right is an even smaller window with a dilapidated modern frame. The first floor has three windows matching the front arrangement, with Georgian 6/6 panes to those on the left and centre. Just right of centre, close to the eaves, is a tiny single-pane window. The rear façade is entirely plain rendered and painted, though it has not been painted for some years and is discoloured.

The front, east, and west elevations sit on a bevelled base with basement lightwells to east and west. The hipped roof is slated with two central rendered chimney stacks bearing long rows of matching octagonal pots. A small hipped-roof dormer with a 6/6 sash frame is positioned to the rear, with two similar dormers to the east. A low parapet runs across the front. Rainwater goods are mainly cast iron.

To the rear of the house stands a large grouping of two and single-storey rubble-built outbuildings.
