Dunallan, 20 Ancrum Road, Dalkeith

Dunallan is an asymmetrical villa dating from around 1884, exhibiting Renaissance detailing and gablet-crowstepped gables. It is constructed of bull-faced snecked ashlar with polished dressings, featuring an eaves cornice detailed with nailheads and a base course. Chamfered window reveals are stopped just short of the cills. Windows have cornices on the south side, with transoms at the first floor on the south and east elevations. Decoratively carved aprons adorn the windows, and pedimented dormerheads are present on the south side.

The south (entrance) elevation is three-bay, with a gabled bay projecting to the right and an ashlar porch in the re-entrant angle at the centre. The porch has a balustraded parapet and fluted Corinthian capitalled piers, with open semicircular arches and a moulded, keystoned doorway, containing a panelled door and plate glass fanlight. A segmental-pedimented dormerheaded window sits above the porch at the first floor. A two-storey canted window is in the bay to the right, topped with a balustraded parapet, and a transomed bipartite window is in the gablehead. A bipartite window is at ground level in the bay to the left, while a pedimented dormerheaded tripartite window is positioned at the first floor.

The east elevation also features three bays. A full-height advanced panel in the bay to the right is corbelled at the first floor and topped with a shaped gable and thistle finial. Bipartite windows are present on both floors. Corinthian nook-shafts support the first-floor window, and a small window above the tripartite window is flanked by pilasters and a pediment detail in the gablehead. A window is located in the stop-chamfered advanced panel at ground level in the bay to the left, leading up to a canted window at the first floor with a foliated cornice and a half-piend roof. A window is centred at ground and first floor levels.

The west elevation displays two gabled bays with three windows at both ground and first floor levels. A glasshouse is adjoined to the right, featuring glazed bricks and thistle-detailed ridge and finials. A single-storey gabled service wing is adjoined to the left, with a window to the south and two windows to the west.

The north (Ancrum Road) elevation has a transomed tripartite stair window at the centre and a window below. A window is set into the gablehead of the bay to the left. A single-storey, asymmetrically M-gabled wing is adjoined to the right, featuring a door to the east, three windows, and a hatch door to the north.

Sash and case windows are fitted with a plate glass glazing pattern, with stained glass depicting St Andrew, St George and St Patrick in the stair window. Coped and rounded stacks are present, with a ridge to the south pitch, gableheads to the west and north, and a wallhead to the right of the north elevation. The roof is covered with grey-green slates and pierced red ridge tiles, with some original metal cans and original rainwater goods retained.

The interior features Jacobean details, including a two-bay carved timber arcade in the hall, and an arcaded balustrade to a dog-leg stair. Fine plasterwork is also present.

The property is enclosed by a semicircular coped rubble boundary wall, with three ball-finialled and corniced circular gatepiers to the northeast, and three pyramidal-capped square piers to the northwest. Decorative thistle-detailed wrought-iron gates complete the setting.
