Caer Edin, Grahamsdyke Avenue, Bo'Ness

Caer Edin is a large, two-story villa dating to 1900, likely designed by W. G. Rowan of Glasgow. The house is built in a Tudor-influenced style and is now horizontally divided into two flats. It is arranged in an L-plan with a three-bay front. The principal elevation is of coursed sandstone ashlar, while the other elevations feature tooled squared and snecked sandstone.

The symmetrical west (principal) elevation is dominated by an advanced doorpiece featuring banded Ionic pilasters and a rectangular fanlight. Above the doorpiece, the date '1900' is set within a stylised keystone, flanked by a segmental hoodmould. A painted timber door with sidelights, the sidelights having stone transoms, provides access to the entrance. A tripartite canted bay window sits above the door, flanked by five-light full-height canted bay gables with overhanging eaves and decorative half-timbering near the apex.

The north elevation incorporates a later concrete staircase providing access to the first-floor flat. The east elevation is characterised by a projecting timber conservatory to the left, featuring dentil detailing in the upper half of the gable, and a single-story wing to the right, with a half-timbered gable.

The windows are timber sash and case, with horns; they have a mixture of panes, predominantly 12-pane, 18-pane, and 9-pane over plate glass. The roof is now covered with modern red tiles, although rosemary tiles remain on the north pitch of the single-story wing on the east side. The property has gable end stacks, a central ridge stack, and wallhead stacks on the east elevation.

The interior is of a high quality, particularly notable for the honey-coloured pine timberwork. The inner entrance door features painted glass upper panels depicting a ship and heraldry, along with a fanlight and sidelights. A panelled hallway boasts an elaborate parquet floor and a coffered plaster ceiling with dentil moulding supported by four timber columns, two of which flank a free-standing fireplace with a timber overmantle and green glazed tiles. The staircase has been blocked off. The panelled drawing room contains an impressive chimneypiece set into an ingleneuk, flanked by angled reeded timber pilasters with cherub capitals and a red veined marble surround. Small heraldic windows depicting a gentleman and lady in 16th-century costume are set into the wall on either side of the fireplace. The panelled dining room has a somewhat simpler columned ingleneuk with a chimneypiece featuring red veined marble. Timber doors are present throughout, some with three panels and others with a diamond pattern to the upper half. A simple glazed cupola is located on the first floor.

Gate piers and boundary walls are present along Grahamsdyke Avenue, featuring a pair of square ashlar gate piers with gabled caps, a sandstone wall with railed scoops and cast-iron gates. To Grahamsdyke Lane, three circular rubble corniced gate piers with rounded caps define the boundary, alongside a high coped rubble wall.
