3, 5, 7 St Marnock Street, Kilmarnock

3, 5, and 7 St Marnock Street in Kilmarnock is a mid-19th century, three-storey, six-bay by six-bay classical corner retail and commercial building. It features painted, stugged ashlar with polished dressings and giant angle pilasters. The building has raised window architraves and margins, with some windows adorned with entablatures, and a cornice with a blocking course.

On the south elevation facing St Marnock Street, the first bay extends to the beginning of the second bay and has a modern shop front with a central door flanked by windows. From the second to the fourth bays, there is a pilastered door surround on the off-centre left, with a small high square window to the left and matching paired windows to the right. The fifth and sixth bays feature a large shop window supported internally by paired columns, with a shop fascia above. A band course forms the sills of six regularly placed first-floor windows, each with entablatures. The second floor has matching architraved windows, and the cornice and blocking course meet the angle pilasters.

The east elevation facing King Street has a recessed central door with shop windows on either side in the first and second bays. From the end of the second bay to the beginning of the fourth bay, there is a boarded shop front. The fourth to sixth bays contain a door with security grilled shop windows flanking it. Modern fascias are present above all shop fronts. Similar to the south elevation, a band course forms the sills of six regularly placed first-floor windows with entablatures, and the second floor has matching architraved windows, with the cornice and blocking course meeting the angle pilasters.

The north elevation adjoins a building of similar height and design on King Street, sharing a stack. The west elevation facing Sandbed Street has four bays and features a pebble-dashed giant end pilaster on the left.

The ground floor shops have modern plate glass windows. The building has a piended grey slate roof with aluminium ridging, flashing, and valleys, along with painted cast-iron rainwater goods and downpipes with decorative hoppers at the centres of the principal elevations.

Inside, the ground floor has been modernized for fitted shops, while the upper floors are used for storage and offices, most of which have been refurbished.
