82, 84, 86 Portland Street, Troon

82, 84, 86 Portland Street in Troon is a near-symmetrical, 2-storey, 3-bay Edwardian baroque building dating from around 1905, with later additions. It features Art Nouveau details and has a large brick addition at the rear. The exterior is made of coursed red sandstone ashlar with polished ashlar dressings, and there is a squared and snecked tooled red sandstone elevation on the southwest side, while the northeast side is brick. The building has a raised base course, corniced ground floor shopfronts, and a corbelled cornice beneath a balustraded parapet that is centered at the first floor. The wallhead is coped.

The ground floor has slender cast-iron columns framing glazed shopfronts, with cast foliate detailing on the brackets. There is a pilastered entrance to the upper floor, and prominent corniced caps sit on the giant order pilasters that divide the first floor bays, which are gabled on the outer left and right.

On the northwest (entrance) elevation, the ground floor features a 2-leaf timber panelled door offset to the left of center, leading to the upper floor, with a tripartite fanlight and flanking stylised pilasters forming the door surround. To the left, there is a shopfront with a recessed, part-glazed timber panelled door, framed by cast iron columns. To the right, another shopfront has a similar design with a recessed, part-glazed timber panelled door in the penultimate bay.

On the first floor, foliate swags frame a central oval window with a raised keystone, and a carved handshake motif is centered in the balustraded parapet above. The outer left and right bays have 3-light canted windows with segmental-arched pediments over the central lights, and oculi are centered in the gables above.

The ground floor features plate glass shopfronts, while the first floor has predominantly replacement glazing, with small-pane casements to the central oval and upper oculi openings. The roof is grey slate with raised skews and corniced red brick apex stacks, along with various circular cans. The interior was not seen in 1997.
