Shambellie House, New Abbey

Shambellie House, located in New Abbey, is a Scottish Baronial mansion designed by architect David Bryce and dated 1856. The building has two storeys with attics over a raised basement, constructed from squared white granite blocks that are partly cherry-caulked, with contrasting red ashlar margins, quoins, crow-steps, corbels, and dressings.

The south-west re-entrant angle features a gabled porch below ground floor level, with a door framed by a lugged architrave and a continuous string course above the basement, which is raised over a plaque above the door. The west elevation has two outer gables, while the south elevation displays twin gables. On the east elevation, there are two canted ground floor windows; the right window is set in a tall gabled bay that is splayed inwards at the basement, corbelled to a chamfer at the first floor, and squared at the main eaves level. To the right, there is a conical-roofed bartizan, and the other window features ball finials. Above, there are two first floor windows with pedimented dormer heads, and a deeply recessed right bay that is corbelled above the ground floor. A conical-roofed turret rises in the re-entrant angle above the eaves, topped with a weathervane finial. The house has sash windows with small panes and central lugs on most window jambs, along with coped wall-head or apex stacks. The roofs are slate, featuring fish-scale patterns on the conical roofs.

The interior, which includes attics completed in 1866 by architect James Barbour of Dumfries, showcases some fine timberwork, particularly on the staircase, as well as cornice plasterwork.
