Ballybot House, 28 Corn Market, Newry, Co Down, BT35 8BG

Ballybot House, formerly known as Dempster's Mill, is a three-storey rubble granite spinning mill with 16 bays, aligned north-south on the west side of Corn Market in Newry. The building has been restored by the Confederation of Community Groups for office and retail use.

The roof is hipped and covered with concrete tiles, with plastic vents in the middle of the front pitch and a vertical metal chimney flue rising from the rear wall. The walls are constructed of random rubble granite with roughly dressed granite quoins. Cast-iron cyma-recta rainwater goods are fitted above a six-course red-brick eaves course, of which the top three courses are corbelled.

The ground floor facade features windows in bays 1, 4, 7, 10, 13 and 16. All are 2/2 bottom-opening sashes in PVC frames with stepped red-brick jambs, shallow segmental brick heads and granite cills. Between these windows, five wide openings with brick jambs and heads have been modified to accommodate modern glazed shop fronts and doors with wooden fascias and roller shutters above, replacing the original window and door openings. The first floor carries 16 equally-spaced windows identical to those on the ground floor. The second floor also has 16 windows in line with those below, identical except for their smaller size, flat heads and cast-concrete cills. The right gable is blank except for a modern ground-floor door opening with a glass panel in a metal frame within a stepped red-brick surround, inserted during refurbishment.

The rear elevation is also 16 bays wide. On the ground floor, bays 1 and 2 contain high tongue-and-groove rectangular panels with doors in their bottom halves. Bays 3 to 6 have four PVC 2/2 bottom-opening windows with concrete cills. Bays 7 to 9 are as bays 1 and 2. Bay 10 is infilled. Bays 11 to 14 match bays 3 to 6 but with granite cills. Bay 15 features an elliptically-headed doorway with a two-leaf tongue-and-groove door and panelled head. Bay 16 matches bays 1 and 2. All openings have stepped jambs in matching red brick and reflect modifications of the original openings. The ghost of two one-storey gabled returns can be seen on bays 1 to 4. The first and second floors carry 16 window openings similar in style to the front elevation, with granite cills on the first floor and concrete cills on the second. On both floors, the opening in the ninth bay from the left is infilled with stone. The left gable is blank except for a high semicircular-headed brick window arch, now with rendered infill. Above and to the side of this opening are three square holes delineated by granite blocks, now infilled, which possibly supported bearing blocks for mill shafts. The top floor walls, although of similar construction to those below, show an evident joint line reflecting the addition of this storey during recent refurbishment.

A building formerly associated with the mill stands to the rear (HB16/28/074B). There is now no trace of the chimney from the steam engine boiler which formerly stood in the yard to the south-west of the mill.
