23 Rubislaw Den South, Aberdeen

25 Rubislaw Den South, including boundary walls, is a double villa built around 1900 by Arthur Clyne. It features two mirrored houses, each two stories high with an attic and four bays. The exterior is made of rough-faced granite, finely finished at the edges of the main elevation, with grey granite on the ground floor and pink granite on the first floor. The rest of the building is constructed from Aberdeen-bond rubble. There is a base course, a ground floor cill course, and a tooled dividing band course that forms the cill course for the first floor.

The north elevation is symmetrical, featuring two doorways in the center bays of the ground floor. These doorways have sunken fillets below the lintels and are flanked by pilastered timber doors with panels and glazed panels, along with letterbox fanlights. Above each doorway, there is a window on the first floor. The outer left and right bays have shallow rectangular tripartite windows with banded rustication on both the ground and first floors, and parapets that break the eaves. The attic features bipartite flat-roofed dormers above, with skylights between the central bays.

The west elevation is asymmetrical and gabled, with a window in the center of the first floor and a single-storey wing adjoining the right side of the ground floor. The south elevation was not visible in 2000. The east elevation is also asymmetrical and gabled, with a window in the center of the first floor and a single-storey wing adjoining the left side of the ground floor.

The villa predominantly has 2-pane timber sash and case windows. The roof is grey slate with decorative terracotta ridges, stone skews with blocked skewputts, and coped gablehead and wallhead stacks that break the pitch, featuring circular cans. The rainwater goods are made of cast iron.

The boundary walls consist of low coped Aberdeen bond granite walls to the north and rubble walls for the remainder.
