Ballymullock House, 160 Ballyboley Road, Ballymullock Lower, Larne, Co Antrim, BT40 2SY

Ballymullock House is a late 19th century farmhouse of no particular architectural distinction, dating to approximately the 1860s or 1870s. Its mixed style reflects the adaptation of Victorian architectural styling to a vernacular context.

The house is constructed as a one and a half storey three-bay building with a two-storey return at one corner. The main entrance faces north-west and is symmetrical, featuring a central semi-circular headed doorway with a narrow semi-circular headed two-pane window to each side. These are flanked by two pairs of coupled windows. Above the entrance, a centrally placed first floor window is enclosed in a gable with painted timber oversailing barge boards and a turned wooden finial.

The roof is laid with Bangor blue slates in regular courses and has chimneys at each extremity of the ridge. These are smooth rendered with offset plinth and moulded cornice, painted brown. The walls are smooth rendered, lined and blocked, and painted white, with raised quoins to the extremities and a moulded plinth in brown. A stone cornice runs along the wall, though interrupted by PVC downpipes at each end. A raised platband at first floor level aligns with the cill of the first floor window.

Windows throughout are vertically hung timber sliding sash, 1 over 1, with horns and moulded stucco surrounds. The sidelights to the doorway are two-pane in similar surrounds. The door itself is a modern panelled wood replacement with a modern door handle and a plain fanlight. Panelled pilasters with moulded capitals rise to a moulded archivolt enclosing the doorway. The doorstep is clad in modern red tiles, and a concrete area extends across the front of the house.

The left-hand gable contains two first floor windows similar to those on the entrance front, with a rectangular flush door to the ground floor coupled with a rectangular window, a modern fixed light with top vent. The wall extends in the same plane to the two-storey rear return. The return has a roof of slates as above with a PVC downpipe. Two pairs of coupled windows to the first floor are rectangular timber sliding sash, vertically hung, 2 over 2, with horns, set in unmoulded openings. The ground floor features one rectangular timber window with a fixed light of two panes with top-hung vents in an unmoulded opening, and a rectangular flush timber door with a four-pane rectangular fanlight. The end gable of the return is blank. Four windows to the rear elevation of the return are all modern rectangular timber fixed lights with top-hung vents in unmoulded openings. The rear wall of the front block has one window to the first floor and two to the ground floor, all with segmental heads. The right-hand gable is similar to the left-hand gable except with three windows, two to the first floor and one to the ground floor, all sashed as on the entrance front.

The house stands in a rural location in open countryside, facing the main road at an angle. Lawns extend to the front and side, with a farm yard to the rear containing undistinguished outbuildings. The front boundary is formed by a low wall, smooth cement rendered and painted, with a front gateway comprising square rendered piers hung with a pair of moderately ornamental iron gates of no special distinction.

Rear buildings appear on the first Ordnance Survey map of 1833, but the front house appears for the first time on the Ordnance Survey map of 1903.
