The central part of the building is a three-storey office block, with a concrete frame, and brick and stone cladding. To its south-west is a two-storey, three-bay former house, No. 323 High Street, converted into offices, and to its rear is a 1970s three-storey, rectangular office block. The three are connected by first- and second-floor corridors, while at ground floor level there is vehicular access to the rear car park. Attached to the front of the building is a tall red-brick tower, rectangular at ground level, but octagonal in top two stages. The tower has a stone cornice, and minimalist clocks on four sides. North-east of the tower is a brick arch, providing access to the reception area, with a balcony above, and stone steps providing direct access to the council chamber and its gallery. These are in a bow-fronted section, clad in reconstituted stone, with ground floor pilasters. Further to the north-east is a seven-bay section with two oriel windows, and then a four-bay section placed further forward, again clad in stone, containing the staff canteen and council members' room.[1]
After the building was completed a series of letters criticising the design appeared in local newspapers.[12] However, the project won a Regional Award (East Anglia) from the Royal Institute of British Architects in 1993,[1] and the architectural historian, Charles Jencks, described the design as a "superb example…of contextualism".[13] The building was grade II listed in 2017.[1]
