23 Warrender Park Terrace, Marchmont, Edinburgh

23 Warrender Park Terrace is a five-storey tenement building, completed in 1883 by Edward Calvert, featuring a mansard attic on the fifth storey and a baronial style with a corner tower. The structure is built from squared and snecked pinkish sandstone, accented with polished ashlar dressings. It has a base course and a string course at the first floor on the north side, which steps up from the first to the second floor on the west side. A corbel table is present at the fourth floor on the north side, with chamfered reveals, panelled doors, and plate glass fanlights.

The north elevation facing Warrender Park Terrace has three bays, excluding the corner tower on the outer right. It features an architraved doorway with recessed polished granite colonnettes and foliate capitals between the second and third bays, along with a relieving arch and a decorative ciphered panel above at the second floor. There are single windows at the first and second bays, with a crowstepped dormerhead linking the bays. The third bay has single windows and a semi-circular dormerhead at the fourth floor.

The corner tower is five stages high, with three lights in each stage. It has a dividing cornice above the ground floor, a corbel table above the second floor, an eaves cornice, and a candle-snuffer roof topped with a lead finial.

The west elevation facing Spottiswoode Street also has three bays, with the first bay advanced and featuring a rounded angle at the return. It includes a roll-moulded doorway flanked by a single window in the first bay, with single windows above and a crowstepped dormerhead linked to a wallhead stack. The second bay has a roll-moulded doorway and single windows above, along with another crowstepped dormerhead. The outer right bay features a full-height canted window that is corbelled to a square at the fourth floor, along with a tripartite window with single lights to the returns at the same level, and a stone finial at the gablehead above. The building has plate glass sash and case windows, a grey slate roof, and various corniced wallhead stacks.

The boundary coping to the streets retains some original railings. The interiors were not seen in 1991.
