43 Mountstuart Road, Rothesay, Bute

44 Mountstuart Road is a double villa designed by John Orkney and dated 1875, showcasing the Alexander Thomson style. This symmetrical, two-storey building features four bays and forms the end of a symmetrical terrace. The design includes a grouped arrangement of 1-2-1, with a recessed central section and single-storey entrance porches on the outer left and right.

The villa is constructed from 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 bays. A bracketed canopy spans the central bays, and the overhanging timber eaves have decorative bargeboards that are missing. The windows have square-headed openings with stylised pilaster mullions at the ground level, and the first-floor windows are surrounded by architraves, corniced with anthemion parapet detailing on the outer bays, featuring columnar mullions. The sides and rear of the building are finished in random rubble sandstone.

On the northern entrance elevation, there is a blind, round-arched alcove at ground level, flanked by tripartite windows and topped with a bracketed canopy. The first floor features bipartite windows that break the eaves. The outer left and right bays have advanced gabled sections with 4-light canted windows at the ground level, while the first floor has bipartite windows centered beneath the apex. The entrance porches contain a timber panelled door on the outer right (No 43) and a replacement part-glazed timber door on the outer left (No 44).

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

The boundary walls consist of a low coped random rubble wall along Mount Stuart Road, featuring a round-arched architraved datestone inscribed "Elysium 1875 JO" at the center. Square-plan, panelled sandstone piers with square caps surmount four corniced, round-arched pediments.
