14-23 Riverside Manor, Riverside Drive, Aberdeen

14-23 Riverside Manor is a neo-Georgian villa designed by Marshall Mackenzie and James Matthews in 1885. This two-storey, three-bay building is situated on a prominent corner site and features later additions and alterations. It is constructed from tooled grey granite ashlar with contrasting dressings and a white granite entrance bay. The villa has a rough-faced base course, cill, dividing and eaves courses, long and short quoins, and surrounds to openings, along with overhanging eaves.

The southeast elevation is symmetrical, highlighted by an advanced central bay with a piended roof that is channelled at the ground floor. It has a pilastered doorpiece with a depressed-arched doorway, featuring a two-leaf panelled timber door and a plate glass fanlight above. There is a canted oriel window on the first floor above the entrance, with single windows on both the ground and first floors in the flanking bays to the left and right.

On the northeast elevation, there are single windows on the ground and first floors of a broad canted bay to the left and in the flanking bay to the right. Adjoining to the right is a single-storey and attic, three-bay granite service wing, which has harled 20th-century additions on the outer right. This wing features regular fenestration on the ground floor and gableted windows breaking the eaves on the attic floor.

The northwest elevation is mostly obscured by the service wing and the 20th-century additions. The southwest elevation has single windows on the ground and first floors of a broad canted bay to the right and in the flanking bay to the left. The adjoining three-bay granite service wing on the left also has harled 20th-century additions, with regular fenestration on the ground floor and gableted windows on the attic floor.

The villa features two-pane timber sash and case windows, a grey slate piended roof with lead ridges, corniced granite ridge stacks with circular cans, and cast-iron rainwater goods.

The interior was not seen in 1999. The property also includes four corniced gatepiers with pyramidal caps at the street, a low coped rough-faced granite boundary wall along Riverside Drive, and high rubble boundary walls elsewhere with rounded coping.
