11 Ann Street, Edinburgh

9 Ann Street in Edinburgh is a classical townhouse built between 1826 and 1829, likely by architect James Milne, with some later additions to the attic. The building features an extensive convex crescented stepped terrace of two-storey, three-bay townhouses with a basement, situated on rising ground to the southeast. The prominent gardens in front enhance the street view, with No 3 and No 13 slightly advanced from the others, and No 13 having a two-bay blind return.

The exterior is constructed from broached ashlar sandstone and coursed squared rubble, with ashlar rybats at the basement. The entrance platts oversail the basement area recess. Architectural details include a banded base course and a narrow banded cill course at the ground floor, along with a deep banded cill course at the first floor that features fluted aprons beneath the windows. No 13 has bowed cast iron balconies at the first floor, and the eaves are corniced. The doorways are moulded, architraved, bracketed, and corniced, with rectangular fanlights that have a geometric glazing pattern. Some later rectangular tile-hung dormers are also present.

On the southwest (rear) elevation, the building is made of coursed rubble with tooled ashlar rybats, lintels, and cills, displaying roughly regular fenestration. The windows are timber sash and case with a 12-pane glazing pattern. The roof is double-pitched, with a piended roof over No 13, covered in grey slates. Corniced broached ashlar ridge stacks are present, some with clay cans, along with cast-iron rain-water goods. A low broached ashlar wall with droved copes and gate rybats edges the gardens, topped with cast-iron railings that incorporate a decorative cast-iron lamp standard with a large bowl shade.

The interior, as seen in 2010, features a decorative classical scheme characterized by intricate plasterwork, large drawing rooms, and stone stairs with well-detailed balustrades, topped by large cupolas.
