80, St John Street

No. 80 St John Street is a terraced house, now used as offices, likely built in the early 1750s. The building features yellow brick set in Flemish bond, stucco, and a roof made of Welsh slate. It stands four storeys high with a two-window range. The ground floor is stuccoed with banded rustication, and the right-hand doorway appears to be a late 20th-century addition with a canopy as part of the cornice. All windows are flat-arched with gauged brick heads on the first, second, and third floors. There is a bracketed cornice above the second floor and a parapet above the third, along with two dormers in the mansard roof.

Inside, the first-floor front room has a fluted dado rail, and the door's architrave and inner panelling, as well as the window embrasures and shutters, are adorned with horizontal fluting. The room also features a frieze with palmette and urn motifs, along with a cornice. The ceiling, likely designed around 1790 in the Adam style, includes a central fan motif, festoons, arabesques, and modeled figures in oval medallions at the four compass points. The fireplace in this room is a late 20th-century replacement. The back room on the first floor has equally sized square panels and a modillion cornice with egg-and-dart ornamentation on the architrave. A round arch leads to the first-floor passage, which is flanked by double pilasters and features a panelled soffit with rosettes.
