42 Bank Street, Kilmarnock

This is a two-storey, three-bay office building, constructed in 1902 to a freestyle Renaissance design by Gabriel Andrew of Andrew & Newlands, and originally built for Mackintosh and Bain. The front of the building is faced with dressed red Ballochmyle stone, while the sides and rear are faced with coursed red sandstone.

The principal, northwest elevation is accessed by three stone steps leading to a central stone door surround. This surround features inset Ionic columns supporting scrolled brackets, an architraved design, and a swept ogee pediment with an engaged ogee pilaster. A timber door is set beneath a separate four-pane fanlight. Tripartite windows are present in the flanking bays, with cills curved into the base course. A full-height central window is positioned above a projecting architraved transom that breaks through the outer windows. Paired architraved band courses create a swept chamfer, with the upper course functioning as the sills for the first-floor windows and containing paired windows to the left. An arched window is centrally recessed, flanked by a single window to the right, with a three-light canted bay to the corner tower - this incorporates alternate rounded and columned quoins. Further paired band courses lead to an over-sailing slated dome, topped by a wrought-iron decorative weathervane.

The northeast elevation adjoins the brick gable wall of the separately listed building at 36-40 Bank Street. The rear, southeast elevation is not visible and is located within a private car park. The southwest elevation is largely concealed by a boundary wall belonging to the Bank of Scotland, revealing polished sandstone, a band course, and the side of the domed tower to the first storey, with coursed sandstone to the remainder and gablehead. The ground floor has plate glass windows divided by stone mullions and astragals, while the upper storey features replacement PVCu glazing. The roof is piended, grey slate, with overhanging eaves. Painted cast-iron rainwater goods are fitted, along with a stone base leading to a brick stack featuring a projecting neck cope and four plain cans.

Internally, the office spaces have been refurbished; a stone staircase is centrally located. Original skirting boards remain, along with some original timber interior doors and plaster cornices.
