20, 21, 22 Warrender Park Terrace, Marchmont, Edinburgh

20, 21, and 22 Warrender Park Terrace is a five-storey and basement tenement building, likely designed by Edward Calvert in 1881. The structure features a mansard attic and has five bays, showcasing baronial architectural details. It is constructed from squared and snecked pink sandstone, accented with polished ashlar dressings. Notable exterior features include a string course at the first floor, a corbel table at the fourth floor that steps down at the center, shaped gables, and stop-chamfered reveals.

On the entrance elevation, there are segmental-arched doorways framed with architraves, featuring recessed polished granite colonnettes and foliate capitals in the second and fourth bays. Single windows are positioned to the right and left of the doorways, with deep-set panelled doors and plate glass fanlights above. Above the second bay, there are single windows, and a crowstepped dormerhead is present at the fourth floor. The fourth bay contains bipartite windows, and the fourth floor dormerhead is linked to a wallhead stack. A relieving arch is found over a simpler doorway with a panelled door and plate glass fanlight in the central third bay, with bipartite windows above and a crowstepped dormerhead linked to the wallhead stack. Full-height canted windows are corbelled to square at the fourth floor in the outer left and right bays, while tripartite windows with single lights are located at the returns on the fourth floor. Cornices are present above the ground and second floors, with a dividing string course above the first floor. A ciphered panel is set at the third floor between the third and fourth bays. The windows are plate glass sash and case. The roof is grey slate, featuring a corniced wallhead stack, coped mutual stacks, stone finials, and beak skewputts.

The interiors were not seen during the inspection in 1991. Decorative cast-iron railings are present at the basement and steps leading up to the entrances.
