13B Forest Road, 13, 13A, Aberdeen

This building, known as 15, 17, and 19 Forest Road, was designed by Walker and Duncan in 1899. It is a two-storey villa with a basement and attic, featuring a four-bay double villa layout. The exterior is made of tooled pink granite ashlar, which is finely finished at the edges, and has a rough-faced granite base course and an eaves course.

The principal elevation is symmetrical, consisting of two mirrored villas that have been subdivided into flats. The central two bays on the ground floor have segmental-arched doorways accessed by stone steps leading to the basement. These doorways feature stop-chamfered reveals and moulded lintels with keystone motifs, with each doorway having a pair of replacement panelled timber doors and a fanlight above. The first floor has regular fenestration, and there are skylights in the attic. Curvilinear-gabled bays are located on the outer left and right sides. Each bay has a four-light canted window that extends through the basement, ground, and first floors, topped with a crenellated parapet that forms a balcony for the attic floor. A round-arched window is centered in the gablehead of the attic, with a stone finial at the apex of the gable.

The southeast elevation is gabled and features windows in the center of the ground, first, and attic floors. The northeast elevation is near-symmetrical with four bays; the ground floor is not visible as of 2000, but the first floor has regular fenestration and bipartite windows in the outer bays. The attic floor has triangular-canted dormers in the center two bays with skylights above, and bipartite rectangular dormers in the outer left and right. The northwest elevation is also gabled, with windows in the center of the ground, first, and attic floors.

Most of the windows are predominantly two-pane timber sash and case, although there are PVCu windows on the first floor of the villa to the right (13 Forest Road). The roof is covered with grey slate and features a terracotta ridge. The gable ends have coped stone skews with blocked skewputts, and there are coped gablehead and ridge stacks with circular cans. The building has cast-iron rainwater goods.

The interiors were not seen in 2000.

The gatepiers and boundary walls consist of a low coped granite boundary wall to the southwest, topped with railings that enclose the basement floor. There are scrolled stone gatepiers on the left shared with 21 Forest Road and a decoratively scrolled gatepier on the right shared with 9 and 11 Forest Road. The remainder of the boundary is made up of rubble walls.
