11 Caughey's Road, Dromore, Co Down, BT25 1DS

11 Caughey's Road, Dromore, Co Down is a two-storey, three-bay formalised vernacular farmhouse dating from around 1800–1819. It represents an increasingly rare building type and demonstrates clear stages of development over approximately two hundred years.

The house originated as a single-storey structure comprising the two bays to the right of the current façade; the left bay was added later as part of its expansion to two storeys. All three bays are approximately the same width.

The pitched roof is covered in very small, thick natural slate (fixed with wooden pegs, according to the owner) and features a flush verge with cement skews and traditional eaves detail. The ridge is laid in terracotta tiles; the verges are raised in concrete. The eaves project with an additional projecting course and moulding below, broken over the windows. Rustic brick chimneys rise to the gables and along the ridge one-third of its length from the left gable (without pots). Galvanised metal half-round gutters on brackets serve the roof.

The façades are whitewashed in lime render; the gables are cement rendered. The principal (north-facing) elevation displays the main entrance: a timber four-panelled door with bolection moulding, flanked by narrow 1/1 sliding sash windows with sills on either side and a quartered semi-circular fanlight above (with curved side transoms). Through the fanlight, the edge of the first floor is visible. To the left of the door, closer to the front, is a 1/1 tripartite sliding sash window with third-width sashes either side of the main light; the boxes are reeded and the sills are painted concrete. To the right, at a distance from the door, is a matching window. All ground floor window sills are set very low. At first floor level are three 6/3 sliding sashes aligned with the ground floor openings, with exposed boxes but no sills.

The east (left) gable is cement rendered and contains a modern timber top-hung window at first floor level, with a rainwater hopper towards the front at eaves level (lacking a downpipe) and a soil vent pipe beside it with drainpipes.

A single-storey, cement-rendered, flat-roofed garage with two timber ledged, braced and battened sliding doors abuts the right gable.

The south-facing rear elevation shows the blank rear wall of the garage at the left. The house elevation to its right contains a square opening with a modern timber window (two top-hung lights over a single lower pane), followed by a rear door of timber, ledged, braced and battened, then a paired 1/1 sliding sash window with exposed boxes. The sill level is higher than on the front elevation. At first floor, all windows are 1/1 timber sliding sashes with concrete sills; the leftmost is centred over its ground floor counterpart, the middle window sits above the rear door and is lower than the others, and the right window is positioned to the right of the ground floor opening. The right (west) gable is abutted by the garage; the wall above is blank and cement rendered.

The house sits at the end of a long laneway from the road, which continues as an unmetalled track through fields. A concrete paved roadway leads to the farmyard past the east gable. To the front, a small field separates the lane from trees on the banks of the River Lagan. To the rear is a concrete yard enclosed by a steep bank to a small field.

The Ordnance Survey maps of 1834 and 1859 show a building of the same size, position and orientation as the current house. By the third edition map of 1919, the house is named "Lagan Vale" and additional outbuildings had appeared; a single outbuilding is recorded on the earlier maps.

The major architectural features remain substantially unchanged, and the building demonstrates the key stages of its development over approximately two centuries, making it a good example of a type now increasingly rare.
