123-125 Warrender Park Road, Marchmont, Edinburgh

123-125 Warrender Park Road is a four-storey corner tenement building, possibly designed by Thomas Gibson around 1880, featuring Scots Baronial details and a corner tower. It marks the junction of terraces, with No 123 having been subdivided into ground floor and basement flats in the early 1970s. The building is constructed of coursed yellow sandstone with polished ashlar dressings, including a base course, a string course at the third floor, and an eaves cornice. The ground and first floors have chamfered reveals, while the upper floors feature stop-chamfered reveals. The entrance includes deep-set panelled doors and plate glass fanlights.

On the south elevation facing Warrender Park Road, the building has four bays, with the corner tower located in the outer right bay. The third bay features a roll-moulded doorway with a bracketed cornice, and above it is a blinded balustraded blocking course with a single window at the first floor. There are single windows on the second and third floors, and a pedimented dormer head linked to a wallhead stack. The first bay also has a roll-moulded doorway, and a hoodmoulded square recessed panel is set between the first and second floors. The second bay has bipartite windows on each floor, a blank heraldic shield in the gablehead, and a stone finial.

The corner tower has a three-stage canted window that transitions to a circular section at the third floor, with machicolated cornices on the outer lights of the canted windows at the first and second floors. The tower is topped with a fishscale conical roof featuring four lucarnes.

On the east elevation facing Marchmont Street, the building has three bays, excluding the corner tower bay. The outer right bay has a full-height canted window with a swept and facetted pyramidal roof. The central bay contains single windows, and there is a cornice above the ground floor window. A cipher panel is located at the second floor of the first bay, with a blinded single window at the third floor. The gable features gabletted crowsteps linking the first and second bays.

The windows are plate glass sash and case style, and the roof is grey slate with corniced wallheads, gableheads, and mutual stacks. Gabletted skewputts and an iron weathervane finial adorn the conical roof, along with finials on two lucarnes.

The interior was not seen in 1991, but the drawing room of No 123 contains a fine white marble fireplace with the original grate and a tiled inset depicting characters and scenes from Sir Walter Scott's Waverley Novels, according to information from the owner in 2001. A low saddleback wall borders the streets.
