15 Queen Street, Edinburgh

15 Queen Street in Edinburgh is a classical terraced house built around 1785 and remodeled by Thomas Purves Marwick between 1897 and 1898. The building is four stories high with a basement and features three bays. It is constructed from droved Craigleith sandstone ashlar, accented with later cream sandstone dressings. The façade has a regular arrangement of windows with moulded architraves. A set of steps leads to a porch supported by Ionic columns on the right, which includes a fluted doorpiece, a panelled door, and a plate glass segmental fanlight. Above the porch, there is a corniced window with a shaped apron on the first floor. The left bays feature a broad flat-roofed canted window at the basement, ground, and first floors, with chamfered arrises and cornices. The second floor has consoled windows with a cornice above, and a later full attic storey is topped with a cornice and blocking course. The basement has a panelled door with two glazed panes and a four-pane fanlight.

The rear elevation is constructed from rubble and also has three bays, with a full attic storey and direct access to the rear from the left window at ground level. The western angle is chamfered, with No. 16 being less deep. The windows are timber sash and case, with plate glass at the front and 12 panes at the rear. The roof is covered with grey slates, although the stack has been demolished.

Inside, the hall features an original bracketed cornice and a later arch leading to the central stairwell. The original tight horseshoe stair has alternate decorative cast-iron banisters with an anthemion motif. The dining room includes a panelled dado, a cornice, and a black slate Roman Doric columned chimneypiece with cream marble inserts, including a central tablet bearing Goldsmith's crest. On the first floor, the full-width drawing room at the front has a panelled dado, a simple carved 19th-century chimneypiece with marble slips, and a dentilled cornice. There is a two-bay room to the rear left with an original cornice, and a similar layout is found on the second floor. The basement has been extended into the rear area, creating a large room supported by a cast-iron column that holds up the original rear wall.

The property is also adorned with 19th-century wrought-iron railings.
