Description
47 and 48 St John's Square are terraced houses with shops that have been converted into offices. The cellars date back to the 16th century, with number 47 likely built in the early 18th century and number 48 in the late 18th century. The buildings are constructed of brick in Flemish bond and have slate roofs. Number 47 has three storeys and a three-window range, while number 48 has four storeys and a two-window range.
Number 47 features a late 19th-century shop front with a dentil cornice and fascia stops at the ground floor. The upper windows are segmental-arched with sashes of original design, and there is a stuccoed panel on the parapet. The right-hand return has a four-window range with similar fenestration and 20th-century shutters set within late 19th-century architraves with a dentil cornice.
Number 48 has an early 20th-century shop front with glazing bars and a panelled door with an overlight at the ground floor. The upper windows are flat-arched with gauged red brick heads, featuring sashes of original design on the first floor (6/6) and second floor (8/8). The parapet has been largely rebuilt, and there are stacks on the party walls.
Inside, both houses have three rows of mid-16th-century brick-built and segmental-vaulted cellars, with Kentish ragstone foundations, traces of an extensive tile floor, and two original connecting doorways, one featuring a four-centred arched head with chamfered stone voussoirs. Number 47 is reported to have panelling and an original roof. The houses are located north of the former priory church of St John of Jerusalem and are likely associated with one of the houses built after the Dissolution in 1540.
