13 King's Gate, Aberdeen

15 King's Gate consists of a pair of two-storey and attic double villas built in 1894 by George Coutts, designed in a Gothic Arts and Crafts style. The villas are constructed of rough-faced coursed grey granite with finely finished margins. A deep base course, ground floor and first floor cill courses, a dividing band course, and an eaves course further define the exterior.

The north (principal) elevation is symmetrical, showing two two-bay semi-detached houses. Each bay contains a three-light canted window extending through the ground and first floors, creating a balcony at the attic level. Above this are pedimented tripartite dormers with nail-head terracotta tympana, a cartouche at the centre, and a decorative bracket at the base of the wallhead stack. Segmental-arched doorways, reached by a flight of stone steps, are set into the ground floor of the outer bays, featuring panelled timber doors with decorative stained-glass fanlights. Keystoned oculi flank the doorways on the left and right. Rectangular bipartite oriel windows are positioned above on the first floor, breaking the eaves with a steeply pitched French roof. A gableted timber dormer is inset, and No. 13 has an iron finial to the apex.

The west elevation is asymmetrical and includes a flat-roofed garage to the left of the ground floor, above which is a stair window. A two-storey addition is on the outer right. A curvilinear-gabled centre bay breaks the eaves, containing a segmental-arched opening to the left of the gablehead and irregular window placement in the bays to the left. The south elevation was not visible in 2000. The east elevation also demonstrates asymmetry, with a two-storey addition to the left. A panelled timber doorway with a letterbox fanlight is on the ground floor of the right return, with a window above. A curvilinear-gabled centre bay breaks the eaves, containing a stair window between the ground and first floors, and a segmental-arched window above. Another panelled timber door, reached by steps, is on the right of the ground floor.

The windows are predominantly two-pane timber sash and case windows, featuring geometrically glazed upper panes. The roof is piended and covered in grey slate, with lead ridges and flashings. Corniced wallhead and gablehead stacks have circular cans. Cast-iron rainwater goods are placed throughout. The interiors were not visible in 2000.

The square-plan corniced granite piers mark the northwest and northeast boundaries, connected by a low coped granite wall. A coped granite rubble dividing wall is also present.
