Tarquin House, 18 West Saville Road, Edinburgh

Tarquin House, located at 18 West Saville Road in Edinburgh, is a later 19th century, two-storey house with an asymmetrical three-bay design and a circular entrance tower. The building features squared and snecked rubble with polished ashlar dressings, including a base course, cornice, quoins, architraved windows, a dividing band course, and an eaves course to the tower.

On the southeast elevation, the entrance features an engaged tower in the central bay, with a panelled timber door and a shouldered plate glass fanlight leading to a porch at the base of the tower. There are narrow shouldered single windows on either side of the entrance, and three narrow round-arched single windows on the first floor above. To the right, there is an advanced gabled bay with a bipartite window on the ground floor that has 4-centred window heads, and a shouldered bipartite window with a capital to the mullion on the first floor above. A moulded ashlar plaque is located above the gable. To the left, there is a bipartite window on the ground floor and a shouldered single window on the first floor above, which breaks the eaves with a hood-mould.

The northwest elevation consists of two bays, with an advanced gabled bay to the right featuring a canted mullioned three-light window on the ground floor with 4-centred window heads. Above, there is a bipartite shouldered window with mullions on the first floor. The left bay has single windows on both the ground and first floors, with the first-floor window breaking the eaves, and a single window in the flat-roofed wing to the left.

The house has 2-pane timber sash and case windows, a grey slate piended roof, and piended hoods over the first-floor windows in the left-hand bays of each elevation. The turret has a conical grey slate roof. Swept metal canopies are present over the advanced window bays on the ground floor, along with iron finials and a wrought-iron window guard on the first floor of the southeast elevation. There is a recessed gabled garage to the east with a sandstone lintel and two-leaf timber doors, each with three glass panels, topped with a grey slate roof.

The property is enclosed by low coped rubble boundary walls along the street, with original cast-iron railings facing Mayfield Road. Original iron gateposts are present with a later wrought-iron gate leading to West Savile Road.
