Southwood, Southwood Road, Troon

Southwood is a 2-storey, asymmetrical T-plan house designed by John A Campbell in 1905, featuring Arts and Crafts and Scots Vernacular architectural styles. The building has undergone later alterations, demolition, and additions. It is constructed of cream-harled brick with very fine blue-grey freestone dressings, and has a partially jettied first floor with crowstepped gables and gabled dormer windows that break the eaves.

On the east front elevation, there is a broad wallhead stack to the left. Steps lead up to a two-leaf timber panelled door set in a roll-moulded surround, topped with a cartouche, located in the second bay from the left. This door is flanked by single windows, with a small bipartite window above, also flanked by two windows that feature carved gableheads breaking the eaves. To the right, there is an asymmetrical gable with a bipartite window adjacent to the wallhead gable.

The south elevation includes a projecting wing to the right, which has a shaped gable for the dormer. A modern conservatory is being built at ground floor in this position as of 2002. There is a linking bay with a French door featuring modern glazing in a moulded surround, topped with a carved panel and a scrolled dormerhead above. To the left, there is an irregularly fenestrated gabled section with two vertically linked windows in a stone surround and an apex stack.

On the west elevation, there is an advanced two-bay section to the left with a later segmental-arched opening in the centre, flanked by windows. Above, a window breaks the eaves in a roll-moulded surround with carving to the gable. A slightly recessed single bay is to the right, with the main wing of the house visible on the outer right and left. A modern conservatory adjoins the east elevation.

Inside, the drawing room features a shallow barrel vault and decorative plasterwork on the ceiling. The windows are timber sash and case with small-pane glazing, although some modern glazing is present at the rear. The slates on the roof are specially selected in shades of brown, orange, and olive-green. The building has corniced wall-head and ridge stacks with circular cans, and decorative cast-iron downpipes with hoppers.

The boundary walls are made of ashlar-coped harled material, with two-leaf decorative wrought-iron gates and obelisk-topped gate piers.
