County Hall

Trowbridge

A new build and refurbishment project of the iconic County Hall building which has transformed the site into a major hub. The existing site comprised the original 1930s County Hall, which is of significant local historic interest and a major 1970s extension. There was limited information on the structure of these existing buildings and investigations were essential to establish the existing structural principles and inform solutions. This included archive searches, visual and intrusive investigations. The approach was to open up the floor plates as much as possible to provide flexibility. The new build included enclosing the courtyard to create a new dynamic public space and Integral produced a variety of options for the roof structure for discussion and costing. This resulted is the selection of an ETFE roof supported on slender steel trusses to provide an elegant and cost effective cover for this public space. Early and ongoing stakeholder liaison was key to establishing the functional requirements for this successful award winning project which has a BREEAM ‘Excellent’ rating.
