54, 56, 58 Montgomery Street, Edinburgh

54, 56, and 58 Montgomery Street in Edinburgh is a classical, near-symmetrical corner tenement block built between 1896 and 1909, possibly designed by John Chesser. This four-storey building features a splayed corner and a distinctive Doric doorpiece with a balcony facing Brunswick Street. The exterior is made of polished ashlar and squared coursed rubble with dressed margins at the rear. Architectural details include a base course, a cill course at the second floor, a dentilled main cornice separating the second and third floors, and an eaves cornice with a blocking course. The windows are regularly spaced, with sunken panelled aprons at the ground floor windows on Brunswick Street and architraved windows on the Brunswick Street elevation and the corner.

The elevation facing Brunswick Street has six bays, with dividing bands between the ground and first floors and a cill cornice at the first floor. On the ground floor, the fourth bay from the left features a timber-panelled door with a letterbox fanlight, framed by attached fluted Greek Doric columns that support an entablature. Above this is a wrought iron balcony with a Greek key border. All floors have bipartite windows in the third and sixth bays from the left.

The northwest corner elevation is a single bay with similar dividing bands and a cill cornice at the first floor, featuring bipartite windows. The north elevation, facing Montgomery Street, has five bays (eight bays at the ground floor). The ground floor includes timber-panelled doors with letterbox fanlights in the second, fourth, and sixth bays from the left. The first floor has a cill course, and there are bipartite windows on all floors in the outer left bay and the second bay from the right.

The building predominantly features plate glass in timber sash and case windows. It has a platform roof covered with grey slate, with stone skews and skewputts. On the north elevation, there is one mutual rendered ridge stack to the left, two wallhead stacks (with an ashlar stack to the left), and one rendered ridge stack to the right. The west elevation has an ashlar wallhead stack and a ridge stack at the center, while the south gable has a gablehead stack. Most stacks are corniced and topped with circular cans.
