Auchenkyle Lodge, Southwood Road, Troon

Auchenkyle House is a large, two-storey and attic Queen Anne style house, built in 1905-7 by Alexander David Hislop and John Campbell. It is set within private grounds and has a distinctive L-plan layout. The house is constructed of red brick with brick quoins, and features steeply sloping, bell-cast slate roofs and a deep modillioned cornice. Segmental-arched windows are present on the ground floor. A prominent north-facing entrance bay is accentuated by a stone doorpiece with a segmental-arch canopy and a ball finial. The garden elevation to the southwest includes an advanced canted bay and a piended roofed bay. Small, piended-roof dormers, and two later conservatory additions are also visible.

The interior, inspected in 2014, displays a high-quality decorative scheme, including timber panelling in the entrance hall, open-well staircase, and corridors. The staircase is characterized by wine glass balusters and a carved handrail. Fine decorative plasterwork is particularly notable in the shallow-vaulted ground floor corridor and public rooms, with motifs of fruit and flowers. Several rooms feature decorative, carved timber fire surrounds. The windows are primarily plate-glass timber sash and case, with a pair of cross-pane lead light windows in the stairwell, and a small circular window on the north elevation. The slates are grey.

A lodge, also designed by Alexander David Hislop in 1905-7, stands on Southwood Road. This is a single-storey and attic, three-bay, square-plan, symmetrical Queen Anne style building with steeply sloping bell-cast roofs, a central chimney stack, and flat-roofed dormers. It is constructed of red brick with a stone base course and deep, overhanging eaves. Raised cills are present on the segmental-arched windows. A later extension with a piend roof has been added to the rear. The interior, viewed in 2014, retains its original room layout, consisting of several smaller rooms and a straight staircase to the upper floor. Windows are mostly 6-over-9-pane timber sash and case on the ground floor, with smaller sash and case windows in the attic storey.
