30-32 Castle Street, Edinburgh

30-32 Castle Street is a classical tenement building constructed between 1792 and 1794, with later alterations. It stands four storeys high, with a basement and two additional attic floors, and features a six-bay facade. The exterior is made of droved cream sandstone ashlar with polished dressings. Channelled pilaster strips frame the elevation and the common stair bay on the left, with band courses above each floor and a mutuled cornice.

The common stair at No 30 has an architraved doorpiece and cornice, topped with a modern timber radiating fanlight. No 32, which has five bays, features a pilastered doorpiece at its center, a fluted frieze, and a decorative metal fanlight applied to the rear of plate glass, along with two-leaf panelled doors. The building has two stepped back tiers of full-width slate-hung attic storeys, made of green slate, added around 1900, each with a central window flanked by canted windows.

The windows are timber sash and case, with 12 panes on the ground and first floors and stair, and 4 panes on the second floor and attics. There is a rendered stack on the left and the roof is covered with grey slates.

Inside, there is a fine arcaded entrance hall that is two bays deep, featuring circular ceilings supported on pendentives and a modern plate glass screen. The inner hall leads to a straight stair down to the basement. The southeast room has a pilaster screen and windows, a panelled dado, and a plain chimneypiece, while the northeast room also has a panelled dado. There is a single-storey and basement extension at the rear. The first-floor flat includes an arched hallway with a swagged frieze, and the front rooms have panelled dados, with the northwest room also featuring a swagged frieze. The second-floor flat has a panelled dado and a 19th-century chimneypiece in the southeast room, along with a swagged overmantle in the northwest room.
