Gretna Hall Hotel And Gate Piers, Gretna Green

Dating primarily to 1710, Gretna Hall Hotel and its gate piers have undergone various additions, including flanking wings and modern extensions to the east. The building began as a small mansion and is now a hotel. It is constructed of rubble stone with ashlar dressings, and has been whitewashed with painted margins or bolection-moulded architraves. The windows are sash windows with small-paned glazing, and the roof is slate.

The original house was two storeys over a basement, comprising five bays. Originally it featured rusticated quoins, which are now visible only at the northwest angle. The south elevation features steps with iron handrails leading to a central porch with a lugged and bolection-moulded architrave set within a pediment. A crest is positioned above the porch. Flanking windows are set within bolection-moulded architraves. The first-floor windows emphasize horizontality, while the basement windows have chamfered margins below a string course; a north-facing window on the first floor also has chamfered margins. The glazing patterns are six and twelve panes. A moulded eaves cornice is present, along with corniced end and central axial stacks.

The interior exhibits an unusual plan with a central chimney stack. A scale and platt stone staircase with bottle nosings is located immediately beside the main entrance. Much of the 18th-century timber balustrade has been encased. A narrow first-floor lobby is present, along with moulded ceiling cornices and panelled doors.

Flanking wings, single-bay and nearly symmetrical, were likely added in the last quarter of the 18th century. These wings project to the south. They feature a Venetian window on both the north and south elevations (one south-facing window has a dropped cill). A low, castellated wing from the 19th century is situated to the west, currently used as toilets, while a rear (north) wing dates to the late 19th century. The interior of the east wing retains original moulded cornices and panelled doors on the first floor. A full-length room from the early 19th century occupies the first floor of the west wing.

The gate piers are a pair of chamfered square piers with moulded caps. The formal grading of the building was changed from Category A to Category B on October 4, 1988, due to subsequent alterations. A contemporary description by MacFarlane notes "Gretna... where Coll Johnston has a fine house."
