74 South Beach, Troon

74 South Beach in Troon is a mid to late 19th century, symmetrical, two-storey, three-bay plain classical house. It features flanking single-storey, single-bay pavilions and is constructed from painted coursed and stugged sandstone with painted dressings. The building has a raised base course, an eaves course beneath corniced eaves, and a blocking course. It includes narrow strip quoins, architraved window surrounds that are pedimented at the ground level, projecting cills, and a pilastered entrance.

On the northeast elevation facing South Beach, there is a timber panelled door with an engraved glass panel at the centre of the ground floor. The door is framed by flanking pilasters, a plain frieze, a cornice, a block pediment, and a raised keystone. Above the entrance, there is a single window aligned with the first floor. To the right of the entrance, there is a small single window at the ground level, while single windows are present at both floors in the outer left and right bays. The flanking pavilions also have single windows centred in them.

The southwest elevation facing the Esplanade features a small opening at the ground level, offset to the left of centre, with a stair window centred above it. Ground floor French doors are located in a canted bay to the right, with a three-light canted window aligned above it on the first floor and a three-light canted dormer above that. There are single windows at both floors in the bay to the left of centre and a single window centred in the pitched wing projecting to the outer left.

The house has 12-pane lying-pane timber sash and case glazing on the South Beach side, while the rear has replacement two-pane timber glazing. The roof is covered with grey slate, featuring piended roofs on the pavilions, raised skews, and replacement rainwater goods. There are coped apex stacks at the northwest and southeast corners with octagonal cans.

The interior was not seen in 1997. The boundary walls consist of a low coped painted wall along South Beach, with square-plan piers flanking the pedestrian entrance topped with swept, corniced pyramidal caps. A taller random rubble wall encloses the site at the rear.
