Regency Square elevation also has a three-light full-height bay window; all other windows are blocked. Grade II listings 22–25 Regency Square Numbers 22–25 Regency Square—at the northwest corner of the square on a short road leading to Preston Street—include the building (number 67) on the corner of that street, which absorbed the house built as number 21 Regency Square. These bow-fronted terraced houses were built in the early 1820s. Number 67 Preston Street is of three storeys and has a shopfront facing west into that street; alongside that is a porch with rusticated decoration and an arched doorway. The Regency Square (south) façade has blocked windows at first- and second-floor level. The four houses facing Regency Square are of three storeys, except number 25 which also has an attic storey. They are of brick faced with painted stucco. Each house has a chimney on its slate roof. Each has an entrance staircase with iron railings, a rusticated ground floor, a single bay window to each storey, an iron balcony at first-floor level, a cornice and a parapet in front of the roof. At numbers 22 to 24, dormer windows cut through the parapet. 38–46 Regency Square Numbers 38–46 Regency Square run alongside the northeast side, and are contemporary with the houses at the northwest corner. A carriage arch ran between numbers 42 and 43. Together with numbers 22–25 and the Grade II*-listed centrepiece of numbers 26–37, the houses form an approximately symmetrical three-part arrangement when viewed from the south. Each house is of stucco-clad brick, and all but number 40 have slate-covered roofs. All houses rise to three storeys and have dormer windows; number 43 has two bay windows on each floor (except the ground floor, where the space is taken up by the carriage arch), but the other houses have only one. Each house also has a balcony, a cornice and a parapet (topped with a balustrade in some cases). 46a Regency Square Number 46a Regency Square stands partly in the square and partly in the passageway opposite the Regency Tavern. It is thought to have been the last property to be completed. Originally built as a single storey architect's studio, it acquired an upper storey in the 1960s and is now a two-storey stucco-faced cottage with three windows on the first floor and a fourth in a recessed wing on the east side.
