4-6 Queen's Terrace, Ayr

4-6 Queen's Terrace is a house built in the later 19th century, featuring two storeys and a near rectangular plan with three bays. The exterior is constructed of coursed sandstone and includes a base course, a cill course at the first floor, an eaves course, a cornice, and a blocking course, along with strip margins. The window openings have painted architraved margins and cill blocks at the ground floor.

The west elevation, which serves as the entrance, has a central doorpiece that is pilastered and corniced, topped with a block pediment. It features a two-leaf timber door and a fanlight, with a single window directly above on the first floor. On both the ground and first floors, there are flanking bipartite windows. Railed steps lead to a recessed entrance for No 6, which also has a corniced and block-pedimented doorpiece and a two-leaf timber door.

The windows are plate glass timber sash and case, with the central first floor window having four panes. The roof is covered with grey slate and features stone skews, coped stacks, and circular cans.

The interior was not seen in 1998. The property also has painted Fleur-de-lis railings that sit atop ashlar copes leading to the steps for No 6.
