Dun A Bhuilg (Loch Sween House), near Achnamara

Dun A Bhuilg, also known as Loch Sween House, near Achnamara, is an Arts and Crafts style house designed by Albert Reginald Powys with John Eric Miers MacGregor and built in 1929. It is a two-storey and attic structure with multiple gables, combining traditional Scottish building methods and materials with contemporary techniques. The house occupies an elevated position west of Kilmory Bay, affording panoramic views towards the mountains of Jura. The walling rubble was sourced from a rocky outcrop immediately behind the property. The design incorporates stylised crowsteps, steeply pitched roofs, and wallhead chimney stacks with mitred slate coverings. Whitewashed exterior walls feature first-floor windows set close to the overhanging eaves.

An outbuilding to the rear is excluded from the listing.

The main, west-facing elevation includes a recessed entrance within a full-height stair outshot. This outshot has a pair of small round windows on the ground floor, two windows above, and a monogrammed date plaque in the gable. A faucet feeds water into a stone basin alongside the entrance steps. A brass bell is mounted on the wall to the left of the door, and the entrance is sheltered by a cast concrete porch featuring crowsteps. A further cast concrete porch is situated above the entrance to the south gable end. The rear elevation displays a broad gable with a wallhead chimney stack, accompanied by smaller windows stepping down to the right of this chimney.

Internally, exposed timber beams are visible on both the ground and first-floor ceilings. The ground floor is finished with quarry tile flooring that slopes to corner drains. The staircase is constructed of solid timber, spiralling around a central post with a rope handrail. A boiler/cloakroom area incorporates a former coal store, featuring a circular coal-hole and a suspended drying rack. The sitting room fireplace features a flush, pedimented lintel flanked by exposed brickwork. Interior doors are faced with plywood, and built-in storage cupboards and drawers are integrated into the walls and attic eaves. The kitchen preserves bespoke timber dressers and a small, glass-walled creamery with slate shelving and a chimney for venting warm air. A walk-in pantry contains bespoke timber units and a serving hatch connecting to the kitchen. The main bedrooms feature timber window seats and timber coving. The attic bedrooms each contain four built-in timber bunk beds. A further bathroom has been added on the first floor.

Multi-pane timber sash and case windows, some with ‘Vita-Glass’ panes, are found in the large sitting room and stair outshot. Smaller multi-pane Crittal windows are present elsewhere. The roof is dark slate, with tightly mitred joints at the valleys. Rainwater goods are primarily cast iron, incorporating decorative rainwater hoppers.
