23 Bishop Street, Rothesay, Bute

19-21 Bishop Street is a terrace of five single-storey cottages with attics, built in the early 19th century. The cottages are arranged in a stepped formation, with two, three, three, two, and three bays, ascending the hill.

No 19 features painted coursed tooled rubble sandstone with raised margins and a raised base course. No 21 is constructed from random rubble cherry-cocked sandstone, with droved red sandstone dressings, raised margins, and a raised base course. No 23 has painted stucco with painted margins and a slight base course on the outer right. No 25 also has painted stucco, painted margins, and a raised base course. No 27 is made of painted coursed rubble with raised margins and a raised base course. All cottages have a lintel course and heavy moulded eaves, with random rubble at the sides.

The west (entrance) elevation of No 19 has an exterior stair leading to a replacement door in the right bay, a single window in the left bay, and a boarded timber storage door at the basement. There is a three-light canted dormer in the left bay and a bipartite window set in a box dormer to the right. No 21 has steps leading to a timber panelled door, flanked by single windows, and three-light canted dormers in the outer left and right bays. No 23 features steps to a replacement door at the center, flanked by single windows, with three-light canted dormers in the outer bays and a pedimented round-arched rooflight at the center.

No 25 has a replacement door in the left bay, a single window in the right bay, a three-light canted dormer above, and a single rooflight to the left. No 27 includes steps to a timber panelled door with a timber mullioned geometric fanlight above, flanking single windows, and three-light canted dormers in the outer bays.

The cottages predominantly feature two-pane timber sash and case windows, with No 21 having replacement eight-pane timber windows. They have graded grey slate roofs, slate-hung dormers, and raised stone skews. The roofs are adorned with a regular arrangement of corniced ridge and apex stacks, along with various circular cans.

The interior was not seen in 1996.
