Coopershill House, Cooperhill, Co. Sligo

Work began around 1755 and did not finish until 1774, the date carved into the keystone above the front door as if the builders wanted no confusion on the point. Whatever caused the delay, the result shows no sign of compromise or afterthought; the five-bay, three-storey house reads as a single coherent idea, its north and south fronts treated with the same careful symmetry, as though the design had been settled once and never revisited.

The house is attributed to Francis Bindon, an architect associated with a number of Irish country houses in this restrained classical idiom, built for A. B. Cooper. The masonry is squared and coursed limestone with polished ashlar quoins, the kind of chamfered corner stones that sharpen a building's edges without drawing attention to themselves, and the window surrounds throughout are Gibbsian, meaning they are broken up with alternating blocks of rustication, a device named after James Gibbs that gives plain stone openings a sculptural quality. The entrance front carries a Wyatt window at second floor level, a tripartite arrangement with a taller central light flanked by narrower ones, and a serliana at the centre of the first floor, the same three-part motif with an arched middle section that appears in Palladian buildings across Ireland and Britain. Sandstone steps, bridging the basement area below, lead up to a hardwood door of fifteen raised-and-fielded panels beneath an interlaced fanlight, with an armorial plaque set into the window sill above the entrance, a small heraldic flourish on an otherwise unornamented facade.

The domestic architecture does not stand alone. To the west lies a stable yard built to a U-plan around 1774, its limestone rubble walls pierced by a segmental carriage arch and a further ashlar archway, with yellow brick surrounds around the doors and windows and old crown glass still visible in the overlights of the timber doors. The coach house nearby, similarly worked in limestone rubble under a pitched slate roof, has since been converted into living accommodation, a practical afterlife for a building type that so often falls into disuse once motor vehicles replace the horse and carriage. The whole group sits within a landscaped demesne of mature parkland and farmland, reached along a tree-lined driveway from the east, the approach itself part of the composition rather than a mere access route.
