12 Dean Terrace, Stockbridge, Edinburgh

11 Dean Terrace in Stockbridge, Edinburgh, is a two-storey and basement terrace of three-bay townhouses designed by James Milne in 1824, featuring a plain classical style. At the corner, there is a slightly advanced three-storey and basement, five-bay tenement pavilion with a small bowed recess. The building is constructed of sandstone ashlar, with a channelled finish at the ground floor and rustication on the southwest elevation facing Carlton Street. The entrance platts overhang the basement area recess leading to the street.

Architectural details include a banded base course, a banded cill course at the first floor, and a corniced eaves course, along with a corniced cill course at the second floor of the corner pavilion. The doorways are inset, featuring timber doors and rectangular fanlights, some of which have a geometric glazing pattern. The first-floor windows are moulded, architraved, and corniced, with individual cast-iron balconies for the townhouse windows and bowed balconies for the two right-hand bays of the southeast elevation of the corner pavilion.

The northwest (rear) elevation is made of random rubble with droved ashlar rybats, cills, and lintels, and has regular fenestration. The windows predominantly feature a 12-pane glazing pattern in timber sash and case, with 6-over-9-pane glazing at the first floor of the corner pavilion. The roof is double-pitched, covered with grey slates, and has corniced ashlar ridge stacks with some octagonal clay cans. There is also a corniced ashlar wallhead stack on the southeast elevation of the corner block, which has a large fielded panel flanked by a stepped blocking course. Cast-iron rainwater goods and cast-iron railings edge the basement area recess to the street.

The interior, as seen in a selection of spaces in 2010, showcases a decorative classical scheme with intricate plasterwork and large drawing rooms. The stone stairs feature a well-detailed cast iron balustrade and timber handrail, topped by large oval cupolas with decorative plasterwork beneath. The large ground and first-floor drawing rooms at the front have decorative cornicing, some ceiling roses, and large marble fireplaces. Cornicing continues throughout the building, becoming less elaborate on the upper floors and in the basement. Working window shutters are present, and there are circular hallways leading to No. 1 Carlton Street. The interiors have undergone later subdivision, which is common throughout the property.
