137 Bentinck Drive, Troon

137 Bentinck Drive in Troon is a two-storey, three-bay house built in the Arts and Crafts style around 1900 by James Miller. The house features an asymmetrical design with a recessed center flanked by gabled and piended bays, and a single-storey porch that is recessed to the outer right. The exterior is finished with whitewashed harl, painted margins, and red tile-hanging beneath the gable head. It has a painted base course, overhanging timber bracketed eaves, and bolted timber bargeboards at the gable heads, which are tile-hung on the west side.

On the west elevation facing Bentinck Drive, there is a bipartite window centered at the ground level and a two-light cat-slide dormer offset to the right above. To the outer right, there is a full-height piended projecting bay with a single window at the ground level, and a bipartite window aligned above on the first floor. The outer left features a projecting gabled bay with a bipartite window at the ground, offset to the right of center, and a canted window on a single timber bracket at the first floor beneath the tile-hung apex. The porch is recessed to the outer right.

The south elevation, which is the entrance side, has five bays. It features red sandstone steps with ball finials leading to an advanced porch that is boldly buttressed in the bays to the left of center. To the right of the porch is a part-glazed timber panelled door, with timber brackets supporting the canopy above. There are single windows in two bays to the left, as well as single windows at ground level in the outer left and right bays. Additionally, there is a single window breaking the eaves beneath the gabled bay to the outer right, and another window breaking the eaves offset to the right of the gabled bay to the left. A buttressed wallhead stack is located to the outer left.

The house features small-paned leaded timber casement glazing throughout, with swept red tile roofs, pantile ridge detailing, and cast-iron rainwater goods. Sandstone coping caps the whitewashed harl ridge and wallhead stacks, which have pantiled buttressing on the south side, and there are circular terracotta cans.

The boundary wall surrounding the property is made of whitewashed harl and has red sandstone coping. It encloses the site at the front and features square-plan piers flanking the entrance, topped with pyramidal sandstone caps, and includes timber gates.
