25, 27, 29 Dundas Street, Edinburgh

25, 27, 29 Dundas Street is a four-storey and basement, nine-bay terraced tenement built in the early 19th century by David Paton. The building features a slightly recessed central bay and a fourth storey designed as a wallehead attic. It is constructed from broached ashlar sandstone, with V-jointed rustication at the principal floor. Architectural details include a base course, band courses between the basement and principal floor, and between the principal and first floors. There are projecting cills at the first and second floors, a cornice at the second floor, and a string course and blocking course at the third floor. The entrance features ashlar steps and platts that oversail the basement.

The west elevation, which is the principal facade, has a nine-panel timber common stair door with a shallow five-pane rectangular fanlight set within a blind rectangular fanlight, centered at the principal floor. This door is flanked by windows and further flanked by a pair of round-arched tripartite doorpieces. At No 25, there is a six-panel timber door with a plate glass semicircular fanlight, while No 29 features a stained glass thermal fanlight. The remaining bays on the outer left contain windows, and there is a two-bay painted shop front on the outer right, featuring a glazed timber door and a plate glass rectangular fanlight, along with a plate glass window. The upper floors have regular fenestration, with cills lowered in two bays to the right at the third floor, and a window guard spanning four bays. The basement includes a two-bay shop front at No 29B, The Torrance Gallery, which has a panelled timber door and a rectangular fanlight, along with a window to the left.

The building has predominantly twelve-pane timber sash and case windows, a grey slate M-roof, and cast-iron rainwater goods. The ridge and gablehead stacks are rendered and coped, with circular cans.

The interiors were not seen in 1997, but there is some evidence of working panelled shutters. The property is also adorned with ashlar copes topped with iron railings featuring spear-headed balusters and urn finials.
