24 Portland Road, Kilmarnock

22 Portland Road in Kilmarnock is a pair of semi-detached, two-storey, two-bay L-plan dwelling houses built around 1855. They are constructed from coursed ashlar, harled, and painted surfaces, featuring a heavy projecting architraved eaves course, a projecting base course, and moulded window margins.

On the north (principal) elevation, No 22 has a door on the ground floor to the right, framed by an architraved surround and topped with a scrolled bracketed canopy that ends in a stepped plaque. To the left, there is a single window with an architraved surround and a projecting lintel. The first floor has two regularly placed bays, with the moulded eaves course extending east beyond the building's line. No 24 mirrors No 22 but has the door and window positions reversed, and the scrolls are missing from the base of the canopy; its moulded eaves course projects west beyond the building's line.

The east elevation features an architraved door surround on the extreme right, shared with No 20, which conceals a service passageway. The rest of this elevation is blind, only interrupted at the attic level by a gutter. The west elevation has a similar arrangement, with an architraved door surround on the extreme left shared with No 26, also concealing a service passageway, and is otherwise blind, broken only at the attic level by a gutter.

No 22 has two-pane timber sash and case windows, while No 24 has replacement fixed plate windows with a top hopper. The roof is piended with grey slate, featuring aluminium ridge and flashings, and the stone skewed gables are flashed over to the west. Both gablehead stacks are missing, and there is concealed guttering on the principal elevation that follows the side elevation of the building, with downpipes at the rear.

Inside, both houses retain some original timber features, such as skirting boards and doors, and they are currently used as business premises.
