33 Mountstuart Road, Rothesay, Bute

33 Mountstuart Road is a double villa built in 1875 by John Orkney, showcasing the Alexander Thomson style. The building is symmetrical, with two stories and four bays, forming the end of a symmetrical terrace. It features a grouped arrangement of 1-2-1, with a recessed center and a single-storey entrance porch on the outer left.

The exterior is constructed of coursed cream sandstone ashlar with polished sandstone dressings. It has a raised base course and corniced canted windows at the ground level in the outer left and right bays. A bracketed canopy spans the central bays, and the building has overhanging timber eaves, with decorative bargeboards on No 33. The windows have square-headed openings, stylised pilaster mullions at the ground level, and architraved surrounds on the first-floor windows, which are corniced with anthemion parapet detailing on the outer left and right, featuring columnar mullions. The sides and rear are finished in random rubble sandstone.

On the north (entrance) elevation, there is a blind, round-arched alcove at the ground level, flanked by tripartite windows and topped with a bracketed canopy. The first floor has bipartite windows that break the eaves, with 4-light canted windows at the ground level in the advanced gabled bays on the outer left and right, and bipartite windows centered beneath the apex at the first floor. There is a corniced side entrance to No 33, with a replacement door set in a piended entrance porch on the outer left (No 34).

The villa features 2-pane timber sash and case windows and has a grey slate roof with replacement rainwater goods. The ridge and wallhead stacks are coped and corniced, with predominantly decorative circular cans.

The interiors were not seen in 1996. The boundary walls consist of a low coped random rubble wall along Mount Stuart Road, with a round-arched architraved datestone inscribed "Elysium 1875 JO" at the center. The boundary also includes square-plan, panelled sandstone piers topped with square caps and four corniced, round-arched pediments.
