Numbers 1 to 12, 12a and 14 to 46 and Attached Front Basement Area, Terrace Railings and Gates

Numbers 1 to 12, 12A, and 14 to 46 form a terrace of 46 houses developed by James Lockier from 1791, likely by William Paty, with construction resuming in 1809 and completing in 1820. The houses are brick, now rendered, with limestone dressings, ashlar to the ground floor of the right-hand three houses. They feature party wall stacks and slate and pantile double mansard roofs. The design is in a Late Georgian style, with each house spanning three storeys, an attic and a basement, and exhibiting a three-window range, with four windows to the houses at the ends of the crescent section.

The terrace is a long, shallow crescent with straight three-house end sections, with the central pair projecting slightly. Giant pilasters articulate the facade from the first-floor sill band to the cornice and parapet. Doorways, located to the left of centre and right, are framed by semicircular arches with moulded surrounds. Teardrop fanlights are above the doorways of numbers 1, 3 and 43 to 46, with most doorways featuring fluted pilaster jambs and six-panelled doors reflecting early and mid-19th century patterns. Number 16 was joined to number 17, the doorway replaced by a window, accompanied by a barley-sugar downpipe along the party wall. Number 2 has an Ionic distyle-in-antis porch, and number 46 incorporates tall Ionic columns supporting a first-floor timber balcony. The original window configuration was five stepped voussoirs to 6/6-pane sashes, now largely replaced with plate glass; most first-floor windows extend to the floor. Later, timber tented balconies have been added, supported by cast-iron brackets and flat stanchions. Wrought-iron railings and gates are present, with varying designs including quatrefoils to numbers 1, 4, 22, 27 to 32, 41 and 43 to 45, a Grecian style to number 33, late Victorian cast-iron to numbers 2, 12, 20 and 40, and wrought-iron lattice with cast-lead ornament elsewhere. Later dormers have altered or reduced the parapet, with full attic storeys to numbers 3, 19, 20, and 25.

Internally, features include an entrance hall divided by a semicircular arch, a dogleg staircase with stick balusters and a curtail, first-floor rooms linked by folding doors, panelled shutters, and six-panel doors. Stone fire surrounds are also present. Attached wrought-iron front basement area railings and gates are embellished with urn finials. The terrace is reputedly the longest in Europe and was completed externally before a period of economic downturn, although the interiors took nearly 30 years to finish. It forms a significant element in the view of Clifton across the Avon.
