13 Danube Street, Edinburgh

19 Danube Street in Edinburgh is an impressive building designed by James Milne in 1824. It features an extensive crescent-shaped terrace of two-storey and basement townhouses in a plain classical style, with a prominent six-bay centre. The façade is constructed from sandstone ashlar, with rustication at the ground floor. The entrance is highlighted by platts that oversail the basement area recess facing the street.

The building has a banded base course and a banded cill course at the first floor, with continuous cast-iron balconies. The advanced centre bays have curved anthemion balconies, and the corniced eaves course is topped by a balustraded parapet, which forms a blocking course for the advanced centre bays. The doorways are inset, featuring timber doors and rectangular fanlights, some of which have a geometric glazing pattern. The windows at the first floor are moulded, architraved, and corniced. There are also some later dormers in the attic behind the parapet.

On the northeast (rear) elevation, the building is made of coursed rubble with droved ashlar rybats, lintels, and cills, displaying a roughly regular fenestration pattern. The windows predominantly feature a twelve-pane glazing pattern in timber sash and case, with a four-over-twelve lying pane glazing at the first floor. The roof is double-pitched and covered with grey slates, while the corniced ashlar ridge stacks are complemented by some clay cans. The building also has cast-iron rainwater goods and cast-iron railings that edge the basement area recess to the street.

Inside, as seen in a selection of interiors in 2010, the decorative classical scheme is characterized by intricate plasterwork, large drawing rooms, and stone stairs with well-detailed balustrades topped by large cupolas. Some areas have been later converted into flats.
