Castle Cottage, Brodick Castle, Arran

Castle Cottage and Greenhyde Cottage, built in 1885, form a pair of single-storey rectangular-plan cottages on the Brodick Castle Estate, situated on north-south falling ground on either side of a track. Castle Cottage stands to the east, Greenhyde to the west.

Both cottages are built of granite rubble with red ashlar sandstone dressings and grey slate roofs. Windows are mostly timber sash and case, and both have coped ashlar end and ridge stacks with tall black cans.

Castle Cottage's west (front) elevation features a modern half-glazed door to the centre right, a 2-pane window to the right, a 12-pane window to the far right, and three windows to the left comprising an 8-light horizontal window to the centre flanked by 12-pane windows. A pitched-roof store with a door is set into the south gable. The east (rear) elevation has a boarded door to the centre right, a miniature 2-pane window and a 12-pane window to the right, a 2-light window to the left, an 8-light horizontal window to the far left, and an early 20th-century projecting window to the outer left. The interior features plasterboard walls and ceilings with a low fireplace of painted coursed stone with timber mantelshelf.

Greenhyde Cottage's east (front) elevation has a door to the centre with windows to the left and right and a miniature 2-pane window immediately right of the door. A lean-to store with external door is set into the south, with another lean-to store on the north featuring a blocked doorway and inserted small horizontal window. The west (rear) elevation has an 8-light horizontal window to the centre and 12-pane windows to the left and right. The interior similarly has plasterboard walls and ceilings, a low fireplace of plastered stone with timber mantelshelf, and vertically boarded timber doors.

Originally thatched and rendered, the cottages were deliberately designed in an archaic vernacular style to evoke an earlier era and provide rustic scenery along the perambulation from the castle to the 'Seven Bridges Walk' up the Mill Burn—an unusual approach for estate cottages of this date. Castle Cottage, the larger of the pair, was originally two separate dwellings. A photograph by Washington Wilson from the mid-1880s documents the original appearance; Greenhyde retains harling to its rear elevation.

By 1954, Castle Cottage had been converted to a single house occupied by a retired couple responsible for stoking the boiler in Brodick Castle and kitchen duties, while Greenhyde was a 2-roomed house occupied by a pensioner looking after chickens and plucking game. Internal arrangements have changed since then. In 1982, both cottages were completely refurbished with new floors and re-roofed. They are currently used as accommodation for staff and volunteers.

An ancillary chicken-rearing house, constructed around 1930 of harled brick with a slated piend roof, stands to the north of Castle Cottage.

These cottages form part of a wider group on the Brodick Castle Estate, comprising Brodick Castle, the Bavarian Summerhouse, Cnocan Burn Road Bridge, the Ice House, the Walled Garden, the Nursery, Main Gates, West Gates, Coastal Boundary Walls, and South Gates.

The Brodick Castle Estate, now a discrete entity, was originally the nucleus of the Lands of Arran. Fought over during the Scottish War of Independence, it became an Earldom and was granted to James Hamilton by his cousin, King James IV, in 1503. The Isle of Arran remained one of the minor estates of the Dukes of Hamilton until the late 19th century. Agricultural improvements in the 18th century, culminating in early 19th-century clearances, displaced the island's small-scale subsistence farming. By the mid-19th century, improved transportation made Brodick an attractive picturesque resort and hunting destination for the Hamiltons, and the castle was substantially rebuilt with surrounding policies laid out as gardens and pleasure grounds. Following the death of the 12th Duke in 1895, Brodick passed to the future Duchess of Montrose. In 1957, the castle and immediately surrounding policies were conveyed to the National Trust for Scotland.

The listing description was revised and the category changed from B to C as part of the National Trust for Scotland Estates Review in 2010–11, with the cottages previously listed individually.
