34, 36 Marlborough Street, Edinburgh

34 and 36 Marlborough Street is an earlier 19th-century building that has undergone later alterations and additions, now divided into two houses. It is a single-storey structure with a basement, featuring a classical design with pavilions on either side. The exterior showcases finely droved, polished ashlar dressings, with ashlar pavilions that are rendered and lined. The side elevations are constructed of rubble with droved ashlar dressings, while the rear elevation is harled. A broad band course separates the basement from the ground floor, complemented by a cornice and blocking course, and the main house has slightly raised quoins.

The northwest (principal) elevation has five steps leading to a pilastered doorpiece, which includes a tablet above the entablature and a deep-set panelled door at the center, topped with a plate glass fanlight. The ground and basement windows in the flanking bays are now blinded at No 34. The pavilions feature full-height bowed windows, with additional windows at the ground and half-basement levels.

On the northeast and southwest (side) elevations, there are two blinded windows with a small window in between. The southeast (rear) elevation includes a small single-storey extension at the center bay (part of No 36) and windows in the flanking bays. The pavilions have gable ends and windows at the ground level.

The building has 16-lying-pane timber sash and case windows, with plate glass windows at the rear. The main house has a grey slate piended roof, while the pavilions also have piended grey slate roofs with gable ends, featuring a ridge over the bowed window at No 34 and a curved roof at No 36. The side elevations of the pavilions have wallhead stacks, rendered for No 34 and a combination of rubble and render for No 36.

The interiors were not seen in 1994. The boundary wall is partly made of rubble with coping and partly rendered with coping.
