20 Battery Place, Rothesay, Bute

20 Battery Place in Rothesay, Bute, is a later 19th-century hotel designed in an asymmetrical Rogue Gothic style. It is a two-storey building with an attic and features three bays. The outer right bay has a full-height five-light bow beneath a concave turret, while the outer left bay has an advanced section with a French-pavilion roof. The building is primarily constructed of yellow sandstone ashlar and includes a raised base course, corbelled corniced eaves, and a corbelled turret.

The ground floor has shouldered-arched openings with architraves, while the first floor features round-arched architraved openings. The attic has simple round-arched openings. There are fluted cast-iron columnar balustered mullions with foliate capitals at both the ground and first floors, and timber mullions in the attic.

On the northwest (entrance) elevation, there is a replacement two-leaf door in the outer left bay, topped by a round-arched plate glass fanlight. The doorpiece includes flanking low projecting walls, three-quarter engaged Corinthian columns with sculpted details at the center, and heavy consoles with foliate detailing that support a projecting entablature. The first floor features an advanced tripartite glazing row in the outer left bay with engaged cast-iron mullions, and above it, there is a single round-arched attic window set in the French-pavilion roof. The outer right bay showcases the full-height five-light bow beneath the concave-turreted roof, which is topped with a cast-iron coronet.

The building has two-pane timber sash and case shouldered windows on the ground floor, and two-pane round-arched timber sash and case windows on the first floor and attic. The roof is a graded grey slate Mansard style with raised stone skews and apex stacks to the northeast and southwest, although the cans are missing. The interior was not seen in 1996.
