12 Kirk Street, Leith, Edinburgh

12 Kirk Street in Leith, Edinburgh, is a group of six mid-19th century, four-storey tenements with cellars and attics, featuring a stripped classical style. The building turns a corner to the northwest and includes a two-storey tenement with matching details to the southeast. The exterior is made of cream sandstone with stugged ashlar on the front and coursed rubble on the rear and sides. Architectural features include a base course, a band course above the ground floor, a cill band course, and chamfered arrises at the doorways.

On the southwest elevation, there are four tenements with six bays each, featuring doorways to the right of the center with replacement doors and three-pane fanlights, except for No. 20. There are single windows flanking the doorways and above in the bays. The corner to the outer left is chamfered at the ground level and corbelled to a square above, with a shouldered angle wallhead stack above it. The roofs have rectangular dormers with half-piended roofs. The two-storey tenement at No. 8 has a raised basement and a transverse stack at the center.

The northwest elevation features a six-bay tenement on the left, with a common stair doorway to the right of the center and the main door flat to the left. There are single windows in the bays above. To the right, there is a four-bay return elevation of the corner tenement, with single windows, one of which is blocked, and another built-up at the outer right, except on the third floor. An angle wallhead stack is located to the right. The roofs again have rectangular dormers with half-piended roofs.

On the northeast (rear) elevation, there are single windows and four-storey square brick projections for each tenement, with doorways on the flanks. The windows are timber sash and case, with some 12-pane designs, mostly featuring plate glass glazing, although some modern replacements are present. The roofs are covered with slate, featuring piend and platform styles, with an angle wallhead stack and broad apex gable stacks, along with prominent tall mutual stacks rising from the wallhead. Recessed downpipes are found on the southwest elevation.

Inside, there is a stone stair at the rear with a plain timber handrail.
