29 Ballydyan Road, Ballydyan, Saintfield, Co Down, BT30 9JP

29 Ballydyan Road is a part two, part single storey gabled farmhouse located on the east side of Ballydyan Road, roughly three miles south of Saintfield, County Down. The building likely assumed much of its present form around the 1870s, though it contains fabric from an earlier dwelling shown on the Ordnance Survey map of 1834, which was then recorded as single storey.

The asymmetrical front elevation faces roughly north. The centre and right portions are two storeys high, while the left section remains single storey. A large modern flat roofed porch with conservatory has been added to the front, with a door facing west. Flanking the porch are two large sash windows with Georgian panes (10/10 lights), one on the single storey portion to the left and one to the right. The first floor contains three unevenly spaced sash windows, all with 6/6 lights. The east and west elevations are blank. To the rear, a two storey flat roofed projection sits roughly at the centre of the main building's facade. This projection has small PVC windows on both its east and west faces, with a PVC door and window on its south face. The rear facade of the main building retains larger sash windows with PVC frames — one at ground floor and one at first floor to the left of the projection, and a further window to the right. An additional window with PVC frame occupies the far right on the single storey section.

The exterior is finished in painted lined render with in-out quoins to the front elevation. The roof is slated with an overhang to the two storey section. Three yellow brick chimneys occupy the gables. Cast iron rainwater goods are present.

The building's development is complex. Evidence suggests the roof was raised at some point, and the asymmetrical window arrangement supports this hypothesis. The Georgian paned sash windows date to approximately 1840s–1850s, though such windows persisted throughout the Irish countryside into the late 19th century, so the raising of the roof may have occurred after 1870. The yellow brick chimneys and roof details suggest work between circa 1870 and 1900. The large front porch dates to around 1970. Further alterations have been carried out between the Second Survey and 2004.

The setting includes a rath opposite the front of the house, which has been landscaped as a garden with steps facing the property. The original earthen bank topped with trees survives around the remainder of the boundary.
