60 Mountstuart Road, Rothesay, Bute

59 Mountstuart Road is a double villa built in 1882 by John Duncan, designed in the style of Alexander Thomson. This symmetrical, two-storey building has four bays and forms the end of a symmetrical terrace. The villa features advanced end bays and a decorative cast-iron columnar verandah at No 59, along with a recessed entrance porch at No 60. The exterior is made of coursed yellow sandstone, which shows some weathering, with polished yellow sandstone dressings. Notable architectural details include a raised base course, dentil detailing beneath the canted eaves at the outer left and right, overhanging timber bracketed eaves, and decorative timber bargeboards at the gableheads. The building also has polished quoins and polished long and short surrounds around the openings, with architraved panelling between the floors and consoled brackets beneath the projecting cills. The sides and rear are constructed of random rubble sandstone.

On the north elevation, the entrance features a replacement door that is offset to the right of centre for No 59. Below the first-floor window, there is a projecting verandah supported by triple sets of cast-iron Ionic columns, with dentil detailing beneath the eaves and decorative cast-iron balustrading. A single window is aligned at the first floor, while both floors have 3-light canted windows centered in a gabled bay to the outer right. For No 60, there is a piended single-storey porch recessed to the outer left, which includes timber bracketed eaves and cast-iron brattishing, along with a replacement door and an opaque-glass fanlight. Single windows at both floors are offset to the left of centre, and there are also 3-light canted windows centered in a gabled bay to the outer left, topped with cast-iron brattishing above a French-pavilion-tower.

The villa predominantly features 2-pane lower and plate-glass upper timber sash and case windows. The roof is made of graded grey slate with fish-scale detailing on the French-pavilion-tower. The original rainwater goods are still in place at the front, along with coped ridge and apex stacks and various circular cans.

The boundary walls consist of a coped part-rendered stepped random rubble wall along Mount Stuart Road, featuring a circular datestone inscribed "Albany Terrace 1882." Square-plan polished sandstone panelled gatepiers flank the entrances, adorned with bracketed cornices and projecting plinths, and there are cast-iron pedestrian entry gates.
