18 Edenduff Terrace, Antrim, Co Antrim, BT41 4NF

18 Edenduff Terrace is a distinctly proportioned mid-Victorian terrace cottage built in the 1860s as part of a worker's housing row on the Shane's Castle estate. Although it has lost some original features, most notably the lattice glazing to its front windows, it retains considerable character and forms part of a group of four similar cottages that together possess definite architectural and historical interest.

The building is a single-storey, three-bay terrace house constructed of rubble basalt, one of a block of four identical cottages. The main entrance faces south.

The entrance elevation is roofed with Bangor blue slates laid in regular courses, finished with dark-toned ridge tiles. A single chimney rises from the right-hand extremity, shared with the adjoining house; it is constructed of red brick with a projecting blue-black brick cornice of three courses topped by a blocking course of red brick and finished with two pots. The basalt rubble walls feature a projecting brick eaves course. Original red brick flat arches head the openings with block dressings, though these are partly obscured by later cement reveals and raised surrounds. Window surrounds are lugged; original lime mortar pointing survives in places, though later cement repairs have been made. Metal guttering and a downpipe run to the right-hand extremity.

The entrance elevation comprises a central doorway flanked by a window on each side. The windows are rectangular timber sliding sash windows with 1 over 1 glazing and horns, painted white with exposed sash boxes painted green; they have projecting painted stone cills. The doorway contains a rectangular flush timber door surmounted by a rectangular fanlight of obscured glass in a moulded timber frame. The door is furnished with a modern metal letterbox and knocker; a concrete doorstep lies below. Black PVC vertical cable trunking is positioned to the left of the doorway.

The rear elevation is similarly single-storey and slated. It retains three original rectangular metal rooflights. The walling matches the entrance front except for the lower portion, which is roughly rendered with lime mortar; old lime mortar pointing generally survives to the masonry. Metal guttering and downpipe are present; the downpipe has a cast iron lower portion with a later metal pipe inserted above. The rear elevation contains a doorway with a small window to the right. Brick dressings face the window and upper part of the doorway, though cement-rendered surrounds have been added to the doorway reveals. The window is a rectangular timber side-hung casement with a projecting painted sandstone cill. The doorway contains a modern rectangular flush timber door set within a broad original timber frame, with a modern metal handle and cement-rendered base blocks flanking the frame.

The cottage stands as part of a terrace of four similar single cottages, itself one block in a row of five such blocks. The terrace occupies a rural setting, facing the main road but set back slightly, with a tarmac access road immediately in front separated from the main road by kerbstones. The heavily wooded demesne of Shane's Castle lies opposite, bounded by a basalt rubble wall, with agricultural land surrounding the remainder of the site. Access to the rear is via a gravelled driveway along the gable of the adjacent house (No. 17) to the west, leading to a small gravelled rear area now overgrown with grass and bounded on the east by vertical timber fencing. A timber outbuilding of no special interest stands immediately to the north, with a garden beyond.

The terrace was built by the O'Neill family as worker housing for the Shane's Castle estate. The precise date of construction is not documented, but the row appears for the first time on the Ordnance Survey map of 1902 and may be tentatively dated to the 1860s. Originally, all houses in the terrace blocks featured lattice-paned windows to the front.
