Meeting room, former muniment room and cells on south side of Guildhall of early C20 date.
MATERIALS Cells: cream brick in Flemish bond and orange brick in English bond; the roof is not visible. Meeting room: magnesian limestone ashlar and orange brick in English bond, the roof is of slate.
PLAN: built on the south side of the Guildhall, against the east side of the Atkinson block and the boundary with the property to the south are single-storey, flat-roofed cells, with a single-storey meeting room at the east end.
EXTERIOR: the front elevation of these two buildings faces north onto a narrow yard and the south side elevation of the Guildhall. The meeting room to the left is built of magnesian limestone blocks. It is single storey with a slightly projecting central gable with coping and kneelers, and a slate roof with two glazed ridge lights and two small, ridge ventilators. At the left-hand end of the building is a doorway with a panelled door and two large, square-headed windows with three-over-three pane sashes. The central gable section has two square-headed windows with two-over-two pane sashes and a doorway to the right with a panelled door. The right-hand end of the building has two square-headed windows now blocked with brick. The outer, east gable wall is built of magnesian limestone blocks with coping and kneelers; the inner gable wall is partly obscured by the cells, with the apex built of cream brick. The single-storey, flat-roofed cells abut the right-hand side of the meeting room and return at the right-hand end to abut the Guildhall. The front elevation is built of cream brick in Flemish bond with concrete coping and two rectangular windows with ashlar frames. The left-hand window has a grid of iron bars, the right-hand window is blocked and obscured. The return elevation has a narrower window, now blocked (with bars remaining behind the brick blocking) with a doorway to the right with a studded timber door.
The south, rear elevation of the cells and meeting room has a patch of cream bricks at the left-hand end but is otherwise of orange brick with various blocked windows and concrete coping. At the right-hand end the meeting room has a projecting, flat-roofed outshot with a pedestrian gateway to the far right opening into a pathway into the yard in front of the Guildhall. The meeting room has a large eaves stack to the left and a smaller eaves stack to the right, both of cream brick. There is a small, central dormer window.
The later, flat-roofed store of cream brick built in front of the right-hand cell window in the front, north elevation and the later glazed, lean-to canopy sloping down from the return elevation are excluded from the listing.
