135 Bentinck Drive, Troon

These are a pair of semi-detached Arts and Crafts style houses, built in 1905-06, with later additions made in 1919 by John Rutherford Johnstone of Troon. In the late 20th century, number 133 was subdivided to create number 37 Bentinck Crescent. The houses form a symmetrical block of six bays. They are constructed with whitewashed harl walls, overhanging timber eaves, and red tile roofs that sweep upwards. A projecting gable breaks the eaves at the centre, while flat-roofed porches are recessed on either side. Single-storey whitewashed harl garage blocks are located to the east.

The west-facing front elevation features a wide, projecting gable spanning four bays, supported by five square piers at ground level. There are two four-light windows centered between the piers at ground level, with small-paned doors set in the re-entrant angles to the left and right, forming porches with swept eaves. Tripartite windows are present at ground level in the bays to the left and right, with two more tripartite windows at the first floor, positioned beneath the apex. Four-light windows are located at ground level in the outer left and right bays, and offset to the left and right of the center are five-light cat-slide dormers that break the eaves.

The north-facing side elevation, shared by numbers 133 Bentinck Drive and 37 Bentinck Crescent, shows a two-storey, three-bay flat-roofed stair projection at the centre. A single door is located at ground level in the bay to the right (number 37), alongside a small single window in the bay to the left. Similarly, small single windows are present in all bays at the first floor. Steps lead to a flat-roofed porch with a two-leaf boarded timber door to the right of number 133, surmounted by cast-iron brattishing. A narrow ground floor light is featured in the recessed and gabled bay to the outer right, with a tripartite window above at the first floor. A bipartite window is set at ground level in the penultimate bay to the outer left, with a tripartite box-dormer above, and a single window at ground level in the outermost bay.

The south-facing side elevation of number 135 is similar, with a two-storey, three bay flat-roofed stair projection at the centre. Small single windows are found at ground level in the bays to the outer left and right, and single windows in all bays at the first floor. Steps lead to a flat-roofed porch with a two-leaf boarded timber door on the left. A narrow ground floor light is recessed within the gabled bay to the outer left, with a tripartite window above at the first floor, off-set to the right of the stack. A bipartite window is set at ground level in the penultimate bay to the outer right, with a tripartite box-dormer above, and a single window at ground level in the outermost bay.

The main elevations feature small-pane timber casement windows, while the projecting stair towers have small-paned leaded glazing with inset heart-shaped decoration. The roof is red tile, with red ridge tiling and cast-iron rainwater goods. Whitewashed harl ridge and apex stacks feature red tile pitches on stylised buttresses, topped with circular terracotta cans.

The interiors were not inspected in 1997.

A stepped whitewashed harl boundary wall encloses the site. Round-arched vehicular and pedestrian entrance arches lead to Bentinck Crescent, flanked by stylised buttresses with pitched red tile caps and decorative wrought-iron gates. A two-leaf boarded timber gate provides access to number 135 from Bentinck Drive.
