Loggia, Barns House, 1 Barns Crescent, Ayr

Barns House comprises a 17th-century gabled wing and an early 19th-century main house. The main house is a two-storey and attic, three-bay structure; the 17th-century wing is a two-storey, three-bay rectangular building. The exterior is painted, droved sandstone on the north-west (entrance) elevation, with painted rubble on the earlier wing, while the rear elevation exposes the stonework. Painted margins highlight the openings.

The north-west (entrance) elevation features a central, Doric pilastered, fluted entrance porch with a timber door. A secondary door is located in the re-entrant angle to the left. Above the entrance is a decorative fanlight and a mutuled cornice supporting a plaque within a block pediment. Single windows are positioned above the entrance and flanking on both the ground and first floors. Canted dormers are situated at the outer left and right at attic level. To the outer right, the earlier gablehead section features two single windows at ground and first floor levels, which are not aligned.

The south-east (rear) elevation is five bays wide, divided into groups of three and two. Each bay of the three-bay section to the left has two openings. A glazed timber door is located on the left at ground level, adjacent to a loggia that extends to the outer left (connecting to the walled garden). The gablehead section to the outer right has two openings at ground level, and a single window at first floor level to the re-entrant angle. Low, single-storey, rubble-built ancillary structures are attached to the north-east side.

The windows are predominantly 12-pane timber sash and case windows. The roof is covered with grey slate, and includes rooflights, stone skews, corniced gablehead stacks, and circular cans.

Inside, fireplaces are found in the rooms, incorporating alabaster, timber, composition, and marble examples. Pelmets and cornices are also present, some featuring gold-leaf work. The main stone staircase has moulded balusters and a timber handrail. The 17th-century wing contains 19th-century timber sinks and kitchen fittings.

The walled garden includes a 1921 garden loggia with brick pillars on the south-east elevation. A plaque is present within the loggia. Urns sit atop the boundary wall, which encloses the garden. An iron gate at the rear of the garden leads into the outer kitchen garden, with ancillary structures attached to the north-east side and a garage to the south.

The gatepiers at the central entrance are square-plan and panelled. These support two-leaf iron gates, and a further two-leaf timber gates are positioned to the outer right of the entrance elevation. An iron gate leads to the walled garden on the south-east elevation, while a timber gate provides access to the garden from the south. A high rubble wall encloses the site, curving at the entrance elevation. A finely detailed, pilastered and pedimented doorpiece is set into the south-west wall. A timber door with a crest above leads to the garden at the rear.
