30 Main Street, Glenluce

30 Main Street in Glenluce is an early to earlier 19th century, two-storey house with an attic and basement, featuring three bays. There is a single-storey rear wing that was raised to two storeys in the later 19th century. The building is constructed of rubble with painted raised margins and granite quoins.

On the north elevation facing Main Street, there is a recessed doorway at the center, framed by a corniced and pilastered doorcase. It has a modern fake-panelled door and an astragalled fanlight, with concrete steps leading down to the basement. The windows are regularly spaced.

Above the outer bays, there are two modern slate-hung canted dormer windows. The central bay has a door to the left and a window to the right, with additional windows in the outer bays at the basement level.

The east elevation features a gable on the right side, with a window at both the ground and first floors, and a small window to the left at the basement. There is a two-storey, two-bay gabled jamb attached to the left, which was raised from a single storey. This section has regular fenestration with brick surrounds at the first floor and blocked openings to the left at the basement. The left angle is chamfered at the ground and corbelled to a square above. The south gable is blank above a modern garage that is attached at ground level.

The west elevation is connected to a lower building, No 28A Main Street. The glazing is modern, featuring a 12-pane astragal pattern, and there are no skews. The rubble gablehead stacks, with red sandstone bands, are located on the east, west, and south sides. The roof is covered with modern tiles, and there are fluted circular cans.

The gabled jamb has a slightly higher ridge line than the original house. There are spearhead iron railings on the east side and modern steel railings on the north side.
