Castle Rock, St Abbs

Castle Rock is a house dating to around 1895, with later additions and alterations. It is a symmetrical, two-story, three-bay gabled building, with a single-story, gabled porch projecting from the centre and a single-story addition at the rear. The external walls are whitewashed harl, with painted dressings. The base of the building is stepped, with a painted band course, and features overhanging timber brackets under the eaves. The bargeboards are predominantly decorative timber, although the main gables at the front have plain bargeboards. Tapering timber finials are also present. Narrow quoin strips are visible, and the openings on the ground floor have square heads with oversailing lintels, while those on the first floor are pointed arches. Projecting cills are found throughout.

The south-east, or entrance, elevation features a part-glazed, gabled porch projecting centrally, with a gabled dormerhead over a recessed pointed-arched window. Full-height gabled bays flank the entrance, each containing a tripartite window at ground level, and pointed-arched windows are aligned at the first floor. A single-story addition is recessed to the outer right, with a timber door offset to the left of the centre.

The south-west elevation shows a three-bay principal block with bipartite windows at ground level in the bays to the right and left. A gabled dormerhead is positioned over a pointed-arched window that breaks through the eaves, off-centre to the right. A recessed gabled porch features steps leading to a two-leaf, part-glazed timber panelled door, which has a four-pane stained fanlight above. A single-story addition is present on the outer left, with a bipartite window offset to the right.

The north-west, or rear, elevation has an irregularly fenestrated single-story addition that runs the full width of the building, with a garage opening to the outer left. A gabled dormerhead sits over a recessed pointed-arched window in the centre, flanked by gabled bays with pointed-arched windows centred at the first floor.

The north-east elevation also features a three-bay principal block with bipartite windows at ground level in the bays to the left and right; a gabled dormerhead is positioned over a pointed-arched window breaking through the eaves off-centre to the left. A single-story projection is on the outer right.

The windows are mainly timber casement windows with fixed multi-pane uppers at ground level, with stained, small-pane uppers to the porch. The first floor has four-pane timber windows within the pointed-arched openings. A modern window is found at the rear, and various rooflights are present. The roof is covered in grey slate, with coped and whitewashed ridge and apex stacks, each topped with circular cans. The interior was not inspected in 1999.
