Westerdunes, Abbotsford Road, North Berwick

Westerdunes, designed by J M Dick Peddie in 1908, is a 2-storey and attic Cotswold Elizabethan style manor house with a cellar to the main house and single storey side projections. It is constructed from squared and snecked Rattlebag stone with ashlar dressings, featuring moulded chamfering to openings and moulded string courses above ground and first floor levels on the north and south elevations of the main house. The windows are fitted with stone mullions and transoms.

The north elevation, which serves as the entrance front, presents a symmetrical main house with three gabled bays linked by a parapet. At the centre is a depressed arched doorway set within a pilastered doorpiece with a recessed porch, topped by a tripartite window with flanking bipartites. The outer bays contain 2-storey multi-light canted windows with parapets above and bipartites in the gable heads. To the right is a single storey projection, set back, with a steeply pitched roof, which was formerly a billiard room and has two small windows with depressed arched lintels to the left and three bipartites to the right. To the left are recessed 2-storey bays with a gabled end bay featuring four bipartites at ground level, a tripartite in the gable, and flanking small lights. A flat-roofed single storey service court to the outer left has a segmental doorway flanked by tripartites and bipartites to the right.

The south elevation displays three gabled bays to the main house with details similar to the north elevation, featuring a tripartite window with a depressed arched doorway at the centre, flanked to the right by a corniced depressed arched doorway with an Elizabethan stair window above. The single storey billiard room, with a gable to the south, contains a tripartite window. A rectangular ashlar porch, flat-roofed, is set in a re-entrant angle. Lower bays to the right of the main house include a gabled outer bay with bipartites at ground and first floor tripartites, along with irregular openings to recessed bays. A single storey service projection to the right has an advanced outer gable.

The east and west elevations each display two gabled bays to the main house with single attic windows. A carved panel adorns the gabled end of the billiard room projection on the west gable. Two gabled bays adjoin the east gable with a flat-roofed extension at ground to the left and a shorter extension to the right enclosing the service court.

Throughout the building, small-pane glazing is used in sash and case windows. Decorative lead gutterheads are present, and gablet coping crowns the gables with moulded, coped gablehead stacks to most gables. The roof is covered with Westmoreland slates.

The interior retains original features following subdivision, including fine plasterwork ceilings and panelling. A notable music room features a classical chimneypiece and Adamesque plaster ceiling.

In the garden stands a summer house comprising a circular Doric colonnade set on a stepped circular base, with a dentil cornice and a leaded dome bearing a fir cone stone finial. It is positioned within a circular balustraded area with moulded ashlar coping and dies, located in the south-west of the garden on the sloping site overlooking the Forth.

A tripartite garden screen features a moulded semi-circular arch to an ashlar overthrow of the gateway with voussoir keystones and a concave parapet. Flanking fluted pilasters carry carved friezes and dentil cornices. Channelled piers with consoles clasping pilasters above create height, while channelled outer piers topped with ball finials are linked to the centre piers by a blocking course and ashlar panels with keystoned arched openings. Decorative wrought-iron gates are set within coped rubble quadrants with outer piers matching those of the screen.

A semi-circular stone 4-seat garden bench with gryphon ends and a central division features decoratively carved back rests with acanthus details. It is positioned by the garden screen, echoing the quadrant's curve, and sits before a flight of steps.

An ornate, vast classical stone capital with foliage carving and cable moulding, adapted as a fountain, serves as the garden's centrepiece, positioned south of the house. It may be an imported piece of ancient sculpture or a replica thereof. Balustraded terrace walls, stone flights of steps, and ball finialled dies complete the garden layout.

Channelled gatepiers and outer piers with ball finials mark the main driveway entrance, with decorative wrought-iron gates set within coped rubble quadrants. Coped rubble boundary walls enclose the property.
