House, Ballymagart Mill, Ballyardle Road, Kilkeel, Newry, Co Down, BT34 4JX

Ballymagart Mill is a two-storey, three-bay house with a two-storey annexe to the right, aligned north-south within a complex of associated mill buildings. The main house has a pitched natural slate roof with brick chimneys to both gables. The walls are wet-dashed and painted with projecting eaves course, and the building has half-round cast iron rainwater goods with a downpipe to the right.

The west elevation contains the main entrance in the second bay from the left. This consists of a vertical tongue-and-groove sheeted door, diagonally sheeted internally and apparently original, with a cast iron knocker. The door sits within a gabled timber porch with a pitched slated roof, turned finial, and decorative bargeboard. Flanking the open porch entrance on both sides, and continuing to the cheeks, are diagonal tongue-and-groove sheeted surfaces to dado level with timber latticework above. A pair of fretted timber corbels rising from the opening reveals support the timber lintel. The left bay has a single window and the right has two; all are 6/6 exposed box sliding sash windows with painted granite cills. Four similar windows to the first floor align with the ground floor openings. The left gable has a ground-floor door and is abutted by a single-storey stained timber lean-to conservatory with a door on its left cheek. At first floor left is a 2/2 sliding sash window.

The rear elevation has a single-storey porch at centre. To its left are two 2/2 sash windows serving the kitchen, and to the right are two similar windows serving the rear corridor. A 6/6 sash half-landing light sits to the right of the porch. At first floor are three 2/2 sash windows: one over the ground floor left window, a second over the porch, and a third over the right window. The porch has a pitched natural slate roof and painted dashed walls, with a 1/1 sliding sash on its right cheek and a multi-paned painted modern timber door on the left cheek.

The right gable is abutted by the lower annexe, with its exposed wall rendered and blank. The annexe has a pitched natural slate roof with two cast iron skylights on the rear pitch. The walls follow the main house treatment but feature three courses of painted brick at eaves level, the middle course set skew. It has small four-paned casements to front and rear walls and a tongue-and-groove sheeted door to the rear. The right gable of the annexe has a pair of vertical sheeted timber top-hung sliding doors with French windows inset behind. Centred over is a pair of four-paned French windows opening onto a cantilevered balconette with modern wrought metal rail.

To the rear, outhouses with natural slated roofs and painted dashed walls enclose a yard on two sides. The east block is single storey with an open central section. The north block comprises a two-storey barn to the right and single-storey stores to the left. To the south and south-east of the house are small vernacular dwellings, both single storey with pitched natural roofs and painted dashed walls. The southern dwelling is two bay with single sliding sash windows to each bay and a tongue-and-groove sheeted door to the right of centre. The south-eastern dwelling is three bay, with a tongue-and-groove sheeted door to the right bay and top-hung casements following the glazing pattern of original sashes. Fields around the site have traditional flat-iron gates between circular stone piers with conical pebble-topped copings.
