Outbuilding, 19 Marine Place, Rothesay, Bute

19 Marine Place is a near-symmetrical, two-storey, three-bay gabled house built around 1865, with later alterations in the 20th century. The exterior features harl-pointed rubble sandstone with polished yellow sandstone dressings. A band course runs at the principal floor, and the house has overhanging timber eaves. The quoins are tooled rubble, and the openings have tooled long and short surrounds with chamfered edges and stone mullions. Gabled round-arched windows break the eaves on the first floor, complemented by decorative timber bargeboards and window-boxes supported by turned timber uprights and scalloped timber balustrades. A steel-balustraded stair is recessed to the outer right, leading to the former entrance of a first-floor flat.

On the northeast elevation, steps lead to a centrally located two-leaf boarded timber door at ground level, which features cast-iron fittings and a slightly roll-moulded surround. Above the door is a small round-arched attic window topped with a tapering finial. To the outer right, there is a bipartite window at ground level with a consoled window-box beneath a single window centered in the finialed gable above. To the outer left, a three-light canted window at ground level is supported by a piended roof with a window-box beneath a single window centered in the finialed gable above.

The house has two- and four-pane timber sash and case windows, a graded grey slate roof, and decorative rainwater goods on the outer left and right. The coped apex stacks are located to the southeast and northwest, with octagonal cans.

The interior was not seen in 1996.

There is also a piended single-storey outbuilding made of harl-pointed random rubble, recessed to the south, with a grey slate roof and a wallhead stack to the southeast, featuring a single octagonal can.

A boundary wall with round-arched rubble coping encloses the site to the northeast and southeast, constructed of harl-pointed random rubble.
