Bogangreen, Coldingham

Bogangreen is a late 18th-century classical house with later additions and alterations, situated near Coldingham. It is a symmetrical, three-storey, three-bay rectangular-plan building with a single-storey service wing at the rear. The walls are harled with cream sandstone ashlar dressings, including a base course, lintel course, corniced eaves and blocking course to the front. Rusticated quoins ornament the front elevation, with narrow quoin strips at the rear and plain margins and projecting cills throughout.

The entrance elevation features a centred, part-glazed two-leaf timber-panelled door with a batwing fanlight, flanked by single windows at ground level. A columnar doorpiece with engaged Tuscan columns and dentilled pediment frames the entrance. A single window is centred at first-floor level, whilst pilastered and corniced tripartite windows (formerly Venetian) occupy the flanking bays. Squat single windows appear in all bays at second-floor level, and a blind thermal window is set in the central wallhead pediment.

The north elevation is largely blind to the principal block, with a single window in the recessed service wing. The rear elevation displays a large round-arched stair window at the centre of the principal block, single windows at ground and second floors to the left, and single windows at all floors to the right. A gabled service wing projects at the centre with a modern lean-to carport adjoining to the right. The south elevation has a single window at ground level to the right of the principal block, with the service wing recessed to the outer left and a lean-to carport adjoining the courtyard wall.

Windows throughout are plate glass in timber sash-and-case frames with six- and twelve-pane glazing. The roof is grey slate with piended sections and harled, corniced and shouldered wallhead stacks to the north and south, with various circular chimney cans.

The interior retains timber-panelled doors and shutters, three timber and composition chimneypieces, and decorative plaster cornices and roses with original colour scheme visible on the drawing room cornice. A timber staircase with balustrade and handrail is present, and the dining room retains original shaped shelves to its presses and dado panelling, as does the drawing room.

Associated with the house is a stable block, a single-storey structure with attic space incorporated within the north wall of the walled garden. It is constructed of heavily-pointed rubble with tooled rubble dressings. The entrance elevation faces north and displays two cart openings at ground level to the right (the outer one with segmental arch), two pedestrian doors and two windows to the left at ground level, and a piended hayloft opening breaking the eaves off-set to the left of centre. The south elevation, facing the walled garden, is blind. The roof is grey slate with piended sections and ridge ventilators.

The walled garden is a near square-plan enclosure of approximately 1,600 square metres to the south-west of the house, bounded by heavily-pointed, coped rubble walls reaching approximately fifteen feet high in places. No remains of formal garden layout survive.

Boundary walls of rubble partially enclose the site, with arched coping to quadrant walls flanking the entrance to the south. Pyramidal-capped square-plan sandstone gatepiers frame the entrance, which is fitted with a hooped iron gate.

The property is noted in the 1856–1858 Ordnance Survey Name Book as "a neat and substantial farm house, pleasantly situated, having a neat walled garden and offices attached." It represents a well-detailed, essentially intact example of late 18th-century classical domestic architecture. Particular architectural features of note include the columnar doorpiece and the large stair opening at the rear. The survival of the stable block, walled garden and boundary walls enhances the significance of the site as a unified composition. Reinstatement of the original Venetian window form would fully restore its classical character.
