Willowbank House, Willowbank Road, Aberdeen

Willowbank House is a late 18th-century villa, with significant additions and alterations carried out around 1843 by J & W Smith. The house is a two-storey structure with a basement and attic, arranged in a four-bay, T-plan, and built of coursed grey granite with finely finished dressings. Features include a base course, raised margins, projecting cills, strip quoins, overhanging eaves to the 19th-century gables, and dormers to the attic floor.

The northeast (principal) elevation is asymmetrical. An advanced, flat-roofed Doric porch, painted white, is located on the ground floor of the penultimate bay to the left. A round-arched niche is on the inside return of the porch, with ashlar steps leading to a two-leaf panelled timber door flanked by glazed panels and topped with a letterbox fanlight. A window sits above the doorway on the first floor, with other windows to the basement, ground and first floors of a flanking bay to the right. Dormers provide light to the attic of the two centre bays. A gabled bay is advanced to the outer left, with windows to the basement and centre of the ground and first floors set within a recessed segmental arch. Another gabled bay is advanced to the outer right, featuring a tripartite window with a balcony on the ground floor and a window to the centre of the first floor.

The northwest elevation is symmetrical, with a gabled form and a flat-roofed bowed bay to the centre of the ground floor, containing three windows. The remainder of the elevation is blank.

The southwest elevation is asymmetrical, with four bays. A flat-roofed porch sits in the penultimate bay to the right, above a basement level, with irregular window placement. The two flanking bays to the left have regular fenestration, with a dormer in the attic of the penultimate bay. A gabled bay is advanced to the outer right, with a flat-roofed addition projecting from the ground floor and connecting to rubble boundary walls, featuring windows to its left and right returns.

The southeast elevation is nearly symmetrical, with three bays and regular fenestration to the basement, ground, and first floors.

The windows are predominantly 12-pane timber sash and case. The roof is covered in grey slate with lead ridges, with stone skews. The building features corniced wallheads, gableheads, and ridge stacks with circular and octagonal cans. Cast-iron rainwater goods are also present.

Inside, a decorative Ionic columned entrance hall and staircase remain, along with some original skirting boards, dado rails, cornicing, and fireplaces.

The site is enclosed by low granite coped rubble walls to the north and higher rubble coped rubble walls to the remainder of the boundary.
