54 Queen Street, Edinburgh

54 Queen Street in Edinburgh is a classical house built around 1790, with internal alterations made in the mid-19th century. The building has three storeys, a basement, and an attic, and features a three-bay façade. It is constructed of polished Craigleith sandstone ashlar, which has been cleaned and includes some replacement stones. The ground floor displays channelled rustication and has long and short quoins. The windows on the first floor are corniced, with lowered cills due to the removal of the cill course. To the left, there is a stop-fluted pilastered doorpiece with a fluted frieze, leading to a pilastered tripartite doorway topped with a cornice that steps back over the door, which has a large semi-circular fanlight with decorative metal glazing. The entrance features a nine-panelled door and a pair of piend-roofed dormers.

The rear elevation is made of coursed rubble and has two bays; the right bay is four storeys and bowed, while the left bay is three storeys and has an attic. The left bay was originally designed with a tripartite window on each floor, but the first floor has been converted to a single window with a Tudor glazing pattern. The building has timber sash and case windows, with 12 panes on the lower floors and 18 panes on the first floor. The roof is covered with grey slates and features an ashlar coped mutual skew and dressed stone mutual stacks, with part of the western stack rendered.

Inside, the entrance hall has a glazed screen, and a curving central stair leads up to the attic, featuring plain square iron banisters that were replaced at the ground level by a panelled straight flight with timber barley-twist banisters and pendant bosses. A circular cupola with a supporting cove enriched with wheat ears is also present. The former dining room has a 19th-century cornice, while the rear right room has later alterations and features a painted carved timber chimneypiece with marble slips. On the first floor, the former drawing room has been subdivided, with re-run cornices, swagged and dentilled cornices, plaster panelled walls, and a panelled dado. There is a door to an inner lobby with a quadripartite rib vault, and the rear room beyond has plaster panelling, a panelled dado, a Gothick panelled Glen Tilt marble chimneypiece, and doors, including what appears to be false double doors to the lobby, a panelled splay to a Tudor-arched window, and a foliate cornice.

The property is also adorned with cast-iron spearhead railings.
