13 Antigua Street, Edinburgh

12 Antigua Street in Edinburgh is a late 18th-century classical double tenement building that features a near-symmetrical design. It stands four storeys tall with an attic and has a nine-bay elevation facing Antigua Street, while the side elevation to Gayfield Square is five storeys high with two bays. The building is constructed of droved ashlar, which is painted at the ground floor, and coursed rubble with droved margins on the side and rear elevations. The eaves cornice is decorated with mutules, and the windows are predominantly arranged in a regular pattern.

On the principal elevation facing Antigua Street, there is a timber panelled door with a six-pane letterbox fanlight located in a plain opening at the center bay, which leads to the stair. To the left, there is a timber shopfront with a doorway at the far left, and to the right, there are two stone-built shopfronts that have been partially altered, sharing a cornice and parapet. The roof features two semi-curved dormers on the left and a single pedimented dormer in the center-right.

The elevation facing Gayfield Square has droved long and short quoins, with a droved ashlar chamfered corner on the right. It includes a timber panelled door at the center bay, with low barred openings to the right and far left. There are oculus windows on the first, second, third, and fourth floors in the left bay, and a window on the first and fifth floors in the right bay.

The rear elevation is eight bays wide and features a nepus gable on the left, along with a single-storey warehouse attached to the ground floor.

In terms of glazing, the building predominantly has 12-pane glazing in timber sash and case windows, with modern plate glass glazing at the ground floor. The fifth floor on the north elevation has four-pane glazing in timber sash and case windows. The curved dormers have grey slate haffits and semi-conical roofs, while the pedimented dormer has a timber fascia, grey slate haffits, and a pitched roof. The front elevation has three rooflights, and the overall roof is pitched and covered with graded grey slates. There is a corniced, droved ashlar ridge stack on the far left, two corniced droved stacks on the rear pitch at the center, one corniced droved gablehead stack on the north gable, and one corniced rubble gablehead stack on the nepus gable at the rear, all with circular cans.
