4-5 and 6 Castle Demesne, Glenarm Castle, (off Straidkilly Road), Glenarm, Ballymena, Co Antrim, BT44 0BD

A plain gabled two-storey terrace of estate workers' houses, dating from perhaps around 1875 or earlier, which forms the east side of a small courtyard at the north end of the Glenarm estate, a short distance north of Glenarm Castle itself. The terrace originally contained three dwellings, though two have since been amalgamated into a single unit. The courtyard complex also includes a single-storey former laundry to the north side, a former dairy to the south, and a small office block to the west.

The front (east) elevation is finished in unpainted render. To the left of centre is a timber-sheeted door with two high-level glazed panels. To the left of this are two sash windows with Georgian panes (6/6), while to the right of the door are three further similar windows. At the far right is a plain timber-sheeted door with a shallow two-pane fanlight, which may be a relatively recent insertion. The right-hand or centre window of the three-window group may originally have been a doorway. At the far left is a pier-like projection, possibly a small remnant of a wall. The right end of the façade merges with the east face of the adjoining stable block. The first floor contains six almost evenly spaced windows matching the ground-floor arrangement. The south gable is finished in unpainted render and is blank, merging with a tall rendered wall which in turn connects to the south façade of the former dairy. On the west elevation, a single-storey return projects to the far left. To the ground floor right of this return are two windows as on the front, followed by a timber-sheeted door and another window at the far right. The first floor has three windows of the same type, with a further window set at half-landing level between the 2nd and 3rd windows. The rear elevation is finished in unpainted render. The return to the far left links to the former laundry building and has a window (3/6) to its south face. The roof is slated with three small Velux windows to the rear. Three rendered chimneysstacks are present, and cast-iron rainwater goods are fitted throughout. The ground immediately adjoining the rear of the dwellings sits approximately 600 millimetres below courtyard level.

The north side of the courtyard is bounded by a large single-storey gabled building that served as the original laundry for the castle, finished in unpainted render. The east gable has a doorway to the left, while to the right it is abutted by the return of house no. 6. The south façade of the laundry has four sash windows with Georgian panes (3/6). To the north the building is abutted by a long lean-to store. The laundry has a slated gabled roof and a single rendered chimneystach.

The south side of the courtyard is bounded by a long single-storey rendered block. The west end of this block formerly housed the dairy, while the east end appears to contain sheds and stores and is lower in height. The north elevation has three timber-sheeted doors to the left and a Georgian-paned sash window (6/6) to the right. The west gable has a doorway, while the east gable appears to be blank. The south façade has two small windows with dilapidated frames. The roof is slated and gabled.

The west side of the courtyard is bounded by a low one-and-a-half-storey gabled building that appears to have contained offices. The west façade has an unusual pointed-arch doorway to the left with a timber-sheeted door, flanked by narrow windows with semicircular-headed frames and margins, all set within geometric pointed-arch openings. To the right of this door and window grouping is a sash window with Georgian panes (6/6, though with blocked panes), followed by a large elliptical-headed doorway for carts with timber-sheeted double doors. Further right is a pedestrian doorway with a timber-sheeted door and rectangular fanlight, with a double sash window at the far right. This façade is finished in unpainted render, part of which (to the left) is lined. The rear (east) elevation has a timber-sheeted door to the left, then a window, the rear of the large cart doorway, then another window with a recent-looking eight-pane frame. This elevation is also finished in unpainted render, with part of it (to the right) lined. The gabled roof is slated and rises slightly to the north end, suggesting the block was built in two sections, a theory supported by differences in the render. The right (south) side of the roof has two small gabled dormers with sash windows (2/2), and a small cast-iron skylight is present to the rear.

Historical records indicate that in 1874 a fire destroyed much of the stable yard and outbuildings at Glenarm Castle, compelling the 11th Earl of Antrim to construct a new range of buildings the following year. It remains unclear whether the entire pre-1874 complex was destroyed. While the plainness of the dwellings might suggest a pre-1874 date, they do not appear to correspond to any buildings shown on the 1857 Ordnance Survey map, indicating they were erected sometime after this date. Map evidence shows that the terrace contained three dwellings until the mid-1970s. This grouping is situated within a conservation area and forms part of a larger estate complex; to the north lies a much more extensive courtyard complex of dwellings and outbuildings recorded separately.
