1 Cornwallis Place, Edinburgh

3 Cornwallis Place in Edinburgh is a four-storey, nine-bay plain classical terrace likely designed by D Cousin in the later 19th century. It is situated on a corner site and features polished ashlar sandstone on the principal floor, with droved ashlar sandstone on the upper floors. The building has a base course, a band course between the principal and first floors, cill courses at the first and third floors, projecting cills at the second floor, and a cornice with a blocking course at the third floor.

On the north (principal) elevation, there are six-panel timber doors with plate glass rectangular fanlights located in the penultimate bay from the right (No 2) and the third bay from the left (No 3). The fenestration is regular in the remaining bays on the principal floor and the upper floors, with bipartite windows in the penultimate bay from the right and a narrow window to the left of the door at No 2.

The west elevation consists of four bays, featuring a six-panel timber door in the penultimate bay from the right at the principal floor (No 1). Windows are present in the other bays on the principal floor and the upper floors, including a window that shares a bay with the door at the principal floor; there are bipartite windows in the outer right bay and the penultimate bay from the left.

The east elevation adjoins another terrace, which is listed separately (15-27 Bellevue Crescent). The south return to the west elevation is a three-bay squared and snecked rubble gable, with windows in the bay to the right of centre and in the outer left and right bays on all floors.

The building predominantly features four-pane timber sash and case windows, cast-iron rainwater goods, and broached ashlar and rendered ridge stacks along with a corniced hipped wallhead stack, which is coped and has circular cans.

The interiors were not seen in 1998 but there is evidence of working panelled shutters. The railings consist of ashlar copes topped with cast-iron railings that have spear-headed finials.
