155-157 High Street, Ayr

155-157 High Street in Ayr is a later 19th-century, three-storey, five-bay tenement located on a corner site, featuring modern shops on the ground floor. The building is constructed of polished red ashlar, with giant pilasters that separate the bays. It has a triglyph frieze at the cornice and a balustraded parapet with dies and a rectangular panel on the southeast elevation.

On the northeast elevation, there are central entrances leading to modern shopfronts at the ground floor. To the right, there is a two-leaf modern glazed door flanked by shop windows, while to the left, there is a single aluminium glazed door also flanked by shop windows. The upper floors have regular fenestration.

The southeast elevation, facing Carrick Street, also has five bays with a modern shopfront at the ground level and regular fenestration on the upper floors, although the central bays are blind. The windows include plate glass (with two panes in the upper sashes) and four-pane timber sash and case windows. The roof is a grey slate piend, with a modern dormer on the southeast elevation.

The interiors were not seen in 1998.
