10, 11 Marchmont Street, Edinburgh

10 and 11 Marchmont Street is a four-storey, four-bay tenement building designed by Edward Calvert in 1883, featuring Barional details and forming part of a terrace. The exterior is made of squared and snecked orange sandstone with contrasting polished ashlar dressings, and the stone has been cleaned. It has a base course and a string course at the first floor. The ground floor openings in the central bays have relieving arched and roll-moulded basket-arches, with panelled doors and plate glass fanlights. The third floor windows break the eaves, and the reveals are stop-chamfered.

On the entrance elevation, there is a doorway with a single window flanking to the right in the second bay, and single windows above. A pedimented dormer head with a stone finial is present. The doorway in the third bay has single windows above, and the third floor window is set in a corbelled panel with a crowstepped dormer head linked to the wallhead stack. Full-height canted windows are corbelled to square at the gable head in the outer left and right bays. There is a relieving arch at the second floor between the second and third bays. The building features four-pane sash and case windows, with replacements at the second floor to the left. The roof is covered with grey slate, and there is a corniced wallhead stack, scroll skewputts, and stone finials at the gable heads.

The interiors were not seen in 1991. There is a low boundary wall to the street.
