135 South Beach, Troon

This is a pair of late 19th century, Baronial-style semi-detached houses, numbered 135 and 137 South Beach, Troon, forming a symmetrical eight-bay block. A two-storey, crowstepped gabled wing is recessed to the right of number 137. The design incorporates engaged three-storey towers in the penultimate bays to the outer left and right, and single-storey square-plan porches are recessed in the outer re-entrant angles.

The buildings are constructed of squared and snecked red bull-faced sandstone, with polished red ashlar dressings. There is no base course; a ground floor string course runs along the outer towers. Nailhead moulding adorns the hoodmoulds that divide the upper floors, while the eaves are corbelled and sit beneath conical caps. Iron finials and overhanging, timber bracketed corniced eaves are recessed at the centre. Openings have chamfered surrounds and sandstone mullions, and the decorative timber gableheads to the central dormers add visual interest.

The west (south beach) elevation features tripartite windows at ground floor level, and bipartite windows on the first floor. Bipartite dormers are aligned above. Single windows are found at both floors in slightly advanced, crowstepped gabled bays on the left and right. Round-arched hoodmoulds with scalloped windowheads at first floor level top the windows in these bays. The towers in the outer bays feature single windows on all floors, with four-light configurations at first and second floor levels. The recessed porches to the left (number 135) have coped, pilastered piers with a plain parapet and corniced eaves, housing a part-glazed timber panelled door with narrow side-lights. The porch to number 137 features columnar piers with corniced eaves, a ball-finialed parapet, a replacement door, narrow side-lights, and a plate glass fanlight. Single windows are set behind these porches, with first-floor chamfers corbelled out to eaves above. An additional two-storey, crowstepped gabled wing recessed to the right of number 137 has single openings on both floors, and a timber balcony with Art Nouveau detail at first floor level.

The windows are predominantly timber sash and case with two panes, although replacement glazing is present at ground and second floor level of number 137. The roof is covered with graded grey slate, with red ridge tiling, crowstepped skews, and graded grey slates to the conical caps. Replacement rainwater goods are fitted throughout. Coped red sandstone ridge and apex stacks rise from the roof, topped with various circular cans.

The interiors were not inspected in 1997.

A boundary wall, constructed of stepped, bull-faced rubble with a polished, chamfered coping, runs along South Beach. Coursed, circular plan piers flank the entrances; they have ball-finialed caps, although the finial is missing from the pier at number 137.
