Cottage in Glenarm Castle Estate ('Lord Antrim's Cottage'), Great Deer Park, Glenarm, County Antrim, BT44 0BD

This rambling, picturesque two storey cottage in the 'Domestic Revival' style was designed by the architects Blackwood and Jury and built in 1920. It stands on the site of an earlier pre-1832 cottage orné (shown on the 1832 and 1858 Ordnance Survey maps and marked 'The Cottage' on the latter), which had apparently been built as a gamekeeper's lodge. The building was originally constructed as a dower house, though in later years it served as accommodation for estate workers. The cottage was greatly extended to the south in 1991, with high quality alterations that included the relocation of bathrooms and the expansion of the kitchen. The property continues to serve as a private dwelling.

The cottage is idyllically sited on a well wooded rise overlooking the Glenarm River, at the southern end of the Glenarm Demesne, approximately two and a half miles south of Glenarm castle and village.

The building displays a variety of gabled and hipped roof bays and projections, with tall chimneys, painted roughcast render, and multi-pane casement windows throughout. Cast iron rainwater goods are present. The roof is covered in natural slate.

The asymmetric west elevation features two storey gabled bays to either side of a central recessed bay. The recessed bay contains a semicircular arch-headed timber door, with multi-pane paired casement windows to the right and at the half landing. At the centre of the roof line is a flat-roofed dormer with two casement windows and a circa 300mm overhang. To the left is a two storey projecting bay with tripartite casement windows to both floors, while a further two storey bay to the right contains a four-casement ground floor window with lattice panes and a paired first floor window. Each bay has a circa 300mm overhanging verge. A date stone inscribed '1920' with a capital 'A' surmounted by an earl's coronet appears below the left side of the dormer.

The south elevation contains a projecting gabled canted bay with a tripartite centred window to the ground floor and a paired window with a Tudor arched head to the first floor. The cants have casement windows on both floors. To the left of the bay, the lower wall is obscured by plant growth. To the right is a ground floor casement window and a paired flat-roofed half dormer to the first floor. A broad chamfered chimney stack flanks the bay to the left at roof level, with a tall narrow chimney stack to the right. A small date stone inscribed 'AD 1991' appears below the first floor window cill. This south elevation reflects the 1991 extension and alterations.

The east elevation features two storey projecting gabled bays to each side of a recessed central bay. The central bay contains French windows to each side of the ground floor and a small window to the first floor, with a wide chimney stack at the ridge. The southern bay incorporates a recent canted sun room with French and multi-pane windows, and casement windows to the bay itself. The northern bay contains casement windows and tripartite casement windows to the upper floor. The southern face of this bay has a canted two storey extension, circa 1991, with tripartite casement windows to both floors and casement windows to the cant sides.

The north elevation contains a left of centre two storey bay with a centred casement window to the ground floor and a sheeted timber door to the left. A small corner infill with single storey height links to adjacent bays, featuring a timber sheeted door to the north face and a small four-pane casement window to the east. To the right of this, the main wall is set back, with paired six-pane casements to the ground floor and a casement window to the first floor. A wide chimney stack rises to the ridge.
