50 Ann Street, Edinburgh

50 Ann Street in Edinburgh is a plain classical corner block built between 1869 and 1871. It is two stories high with a basement and features a slightly recessed bowed corner. The building is constructed from stugged sandstone ashlar, with a droved finish at the basement and stugged, squared, and snecked stone on the northwest gable. It has a banded base course, a banded lintel course at the ground floor, and a narrow banded cill course at the first floor, topped with a corniced eaves course. The openings are bevelled architraved and corniced at the ground floor.

On the southeast elevation, which faces Upper Dean Terrace, there are roughly two bays with a prominent bowed bay on the left. This elevation features shouldered arched bi-partite windows with a stone mullion to the right and tri-partite windows with stone mullions in the bowed corner bay. The southwest elevation, facing Ann Street, also has two bays and includes a moulded architraved and corniced doorway with a panelled timber door and a rectangular fanlight.

The northwest (rear) elevation is made of squared and snecked sandstone with tooled ashlar dressings and has regular fenestration. The windows are timber sash and case with plate glass. The pitched roof is covered with grey slates, featuring sandstone skews and some moulded skewputts. There are shouldered and corniced broached ashlar wallhead stacks on the southwest and northwest elevations, along with a corniced broached ashlar end stack on the northeast, and some clay cans. The building has cast-iron rain-water goods and a low wall made of stugged, squared, and snecked stone with droved copes and gate rybats edging the gardens to the street, topped with cast-iron railings that incorporate a decorative cast-iron lamp standard with a large bowl shade.

Inside, the building features a decorative classical scheme characterized by intricate plasterwork and a large drawing room. There is a stone staircase with a well-detailed cast iron balustrade and a timber handrail, topped by a large rectangular cupola. The principal rooms and entrance hall have decorative cornicing and some ceiling roses, along with working window shutters. There have been some later subdivisions within the interior.
