Garden House, Bank House, 19 Bank Street, Wigtown

Bank House, located at 19 Bank Street in Wigtown, is a mid-19th century, two-storey house with a basement and classical architectural details. The main elevation features three bays facing south, with gable ends to the east and west. The northern wing is also two-storey and has a piended roof, while there is a single-storey porch that was formerly a bank office to the northwest.

The south elevation is constructed of polished sandstone, featuring banded base courses and rusticated quoins. The windows have raised flat architraves, with sash and case windows that include plate glass glazing. There is a band course at the first floor cills, an eaves band, and an eaves cornice. The sandstone skews are complemented by corniced end stacks, some of which have octagonal cans, and the slate roofs include modern rooflights. Access to the central porch is via steps, with square pillars that support a cornice and block pediment. The entrance features a panelled door with a fanlight. The flanks and rear of the house are built of rubble with rusticated quoins, and the irregularly fenestrated northern wing has a roof platform with a sandstone balustrade and stacks at the corners. The single-storey extension to the northwest has a door and is constructed of similar masonry, topped with a deep coped rubble parapet. The doorway features a corniced architrave and lugged design, with double-leaf panelled doors. There is a bipartite window to the left, which now has a modern door.

Inside, the house boasts good plaster cornices, panelled doors and shutters, and a staircase with elegant cast-iron balusters. Surrounding the house is a tall couped rubble garden wall. At the southeast and northeast angles, there are two single-storey square rubble garden pavilions with rusticated quoins and arched sandstone-margined windows. The pavilion to the northeast has a slated pyramidal roof, while the one to the southeast is currently roofless as of 1987. The centre of the south wall features a pair of tall coped rusticated gatepiers with cast-iron gates, while the north wall has a pair of smaller coped rusticated gatepiers and cast-iron gates.
