57, Queen Charlotte Street

57 Queen Charlotte Street is an attached house that has been converted into an office. It was built in the early 19th century and features a limestone ashlar exterior with a brick party wall stack, although the roof is not visible. The building has a double-depth plan and is designed in a late Georgian style, standing four storeys tall with a two-window range. The front is plain, with first-floor sill bands, a frieze, a cornice, and a parapet. The left-hand side has a semicircular-arched doorway with a key and imposts, a four-light fanlight, and a six-panel door. The windows are six-over-six pane sashes, with three-over-three panes on the fourth floor. The rear elevation includes nine-over-nine pane stair light sashes with thick bars.

Inside, the building retains a largely complete 18th-century interior. The left-hand dogleg stair on the ground floor features barleysugar balusters, while the upper floors have turned balusters, uncut string, and square newels with pyramidal pendants. The interior also includes restored dados and cornices, six-panel doors, and panelled shutters. The second-floor has a stone fire surround with a 19th-century iron hob grate, and the hall features late 19th-century style plaster decoration.
