84 Castle Street, Ballycastle, Co Antrim, BT54 6AR

This is a three-storey, four-bay wide terrace house, likely of mid-18th century origin, built in a Georgian style, although it lacks symmetry. It is situated at the bottom end of Castle Street, where it turns into The Diamond, and its roof line is level with numbers 5 and 4 The Diamond. The building's construction probably dates from between 1820 and 1839, and may incorporate elements of an earlier structure built around 1740 by Hugh Boyd.

The building features a shopfront on the left-hand side of the ground floor, with a double-panelled entrance door flanked by simple pilasters, and a two-pane light above. A double glazed tripartite window arrangement is incorporated into the shopfront, flanked by a third pilaster, with a marble stall raiser beneath. The upper floors have a mix of six-over-six double glazed sash windows, with a larger sash window to the left of the shopfront on the first floor. There are three windows aligning at each floor. The natural slate roof has cast aluminium gutters on projecting brackets. All windows are double glazed, with glazing bars applied to the front of the glass.

The rear elevation includes a wide, two-storey back return that occupies most of the plot width, with a ridge line above the eaves of the main building. The rear of the main building incorporates a circular window. The roof has ½ round gutters and a single aluminium downpipe. The building respects the established building line of the terrace.

The current owner purchased the building in 1999, and it was renovated by Connor McGirr Architects with funding from Urban Development Grants. Very little of the original historic fabric remains, and exterior details are not faithful reproductions of the originals. It is located within the Ballycastle Conservation Area.
