55, 57, and 59 High Street in Ayr is a late 18th century tenement building that stands three stories tall with an attic and features a near square plan. The ground floor has been modernized with a shopfront, while the upper levels are finished with painted harl. Notable architectural details include a wide shallow band course between the first and second floors, an eaves course, a cornice, and a blocking course. The east and north elevations are accented with strip quoins, and the windows on the upper floors have painted margins.

The entrance elevation features a central entrance leading to the ground floor shop, which has a two-leaf glazed timber door flanked by shop windows. The first and second floors have regular window arrangements, and there are piended dormers on the outer left and right sides of the attic.

The north side elevation has three bays and includes a slim twin-columned Roman Doric corniced doorpiece to the right of the modern shopfront, with a timber door and a decorative letterbox fanlight. The first and second floors maintain a regular fenestration pattern, while the gablehead has two smaller attic windows.

The upper sashes of the windows on the first and second floors have six panes, while the lower sashes are made of plate glass. The attic windows on the north elevation also have six panes, and the dormers on the east elevation feature four and twelve panes. The roof is covered with grey slate and includes stone skews, scrolled skewputts, gablehead stacks, and polygonal cans on the north side. The interior was not seen in 1998.
