Coach House, Hewison House, 44 Minister's Brae, Rothesay, Bute

This is a mid to later 19th century building that originally served as a manse, and was later converted into three separate flats in the mid to later 20th century. It is two storeys high with a basement, and built in a plain classical style with a symmetrical front facade. Alterations have been made to the rear.

The building is constructed of harl-pointed random rubble sandstone with raised, polished margins, and pilastered quoins. It has a raised base course and a lintel course beneath corniced eaves. The surrounds to the openings are of stugged long and short rubble, with projecting cills. A columnar doorpiece is located centrally on the front elevation. A harled, single-storey, single-bay outbuilding is situated to the northeast (originally the coach-house), and a single-storey, three-bay outbuilding of whin rubble stands to the east (originally the stables).

The front (east) elevation features a replacement door, centred at ground level, with a modern fanlight. The doorpiece projects forward and comprises flanking Doric columns, a plain frieze, a cornice, and a block pediment. The remaining bays on both floors are regularly fenestrated.

The rear (west) elevation incorporates a staircase leading to a two-leaf timber door, centred on the first floor, which provides access to the upper flat. Single windows are located in the bays to the outer left and right. A balustraded platform with a modern door is offset to the left of centre at ground level. A small single window is positioned centrally, flanked by single windows in the outer bays. The basement flat has a modern door, also offset to the left of centre, with single windows to the left and right.

Modern aluminium windows have been installed to the front and rear, along with replacement rainwater goods. The roof is piended and covered with grey slate, featuring raised stone skews. Corniced apex stacks are present on the north (sandstone) and south (brick replacement) sides, along with various circular cans.

The outbuilding formerly used as a coach-house has a blind single window centred beneath the apex on its western elevation and a garage opening on the south side. It has a graded grey slate roof with raised skews.

The outbuilding formerly used as stables has a single boarded timber door centred at ground level on its western elevation, a single window in the bay to the outer right, and a slit opening in the bay to the outer left. It also has a graded grey slate roof, raised skews, and corniced apex stacks to the north and south, though the cans are now missing.

The interior of the building was not inspected in 1996.

Rubble coped random rubble boundary walls run along Minister's Brae, with square-plan sandstone piers flanking the entrance. These piers have prominent cornices, which are detached and located off-centre to the right. A rubble wall along Mount Pleasant Road has round-arched coping and stugged dressings.
