Remodelling of the 1930s County Hall and its 1970s extension to create a civic centre that incorporates a town library and registry office

The office provides an open plan working environment for 1,500 Wiltshire Council employees.

The introduction of a new ETFE inflated roof to an existing underutilised external courtyard creates an internal public space overlooked by the open plan office above. The courtyard houses a coffee bar, main reception, information points, exhibition area and seating. The remaining sides of the courtyard are opened up to a new public library, dining area, registry services and meeting rooms.

An underfloor plenum provides displacement ventilation to the atrium via floor grilles and vents through fixed furniture. A new three-storey link between the existing County Hall and 1970s extension forms one side of the courtyard and accommodates a new main public entrance, lifts and stairs, cantilevered meeting rooms to upper floors, copper mesh and dichroic colour-changing glass.

A 40 per cent reduction in carbon emissions has been achieved by thermal upgrades to the walls and roof, replacement fenestration and a comprehensive services overhaul.
