4 Milltown Road, Milltown, Lislea, Newry, Co. Armagh, BT35 9UF

Four Milltown Road is an early nineteenth-century vernacular building dating from between 1820 and 1839. It stands set back from the east side of a minor road branching off the B30 that leads southwards towards Forkill, approximately two miles from Camlough on the Camlough–Newtownhamilton road. The house faces west.

The building is two storeys with a harled and whitened finish to the front elevation and exposed whitened stone to the rear. The roof is covered with natural slate, and the chimney is constructed of dark brick with corbelling. Rainwater goods throughout are plastic. The gables are plain without openings. Evidence of rough quoin stones built into the walls suggests the original building was of a lesser size than it now appears, and quoin stones remain visible at the north extremity of the original structure and in the corresponding position on the rear elevation.

The main western elevation contains a windbreak porch positioned at the right-hand extremity with a modern timber-sheeted half door and a natural slate lean-to roof. To the left of the porch are two windows, both vertically sliding sashes: the lower one divided into two vertically with splayed sash stops, and the upper one divided into two vertically. The sills are of traditional depth at their leading faces. The building extends to the left in modified two-storey construction, with an external staircase rising to a timber-sheeted door that gave access to the original storage chamber, and below this a ground-level entrance leading to the byre.

Attached to the south gable is a single-storey unit of concrete block construction with a monopitch corrugated roof, fronted by a harled façade matching the main building. This unit contains a windbreak porch with a half door and two vertically sliding windows with sashes divided into two vertically and moulded sash stops. To the north gable is attached a further extension of corrugated sheeting with steel-framed windows.

The east-facing rear elevation of the main house is pierced by three openings: a small plain window at upper level, a plain vertical-shaped window at lower level, and a modern top-hung window at high level.

The house appears on the first edition of the Ordnance Survey map of 1833–5 and the second edition of 1860, both showing small structures at front and rear. The plan form of the original structure survives, preserving most of the elements characteristic of vernacular building tradition, though later additions and alterations have modified the overall form.
