County Hall

Wiltshire Council are transforming the way they deliver services and the Trowbridge County Hall site has become a major hub.

The project
Library services have been brought within the building along with a cafe and registry office. From concept stage the council emphasised that the project is about the delivery of services, with the building being one of many tools to achieve this.

The engineering challenges
Many stakeholders operate from this town centre building and future flexibility was a key criterion in the design work.

The existing site comprised the original 1930s County Hall and a major 1970s extension. One challenge was the limited information on the structure of these existing buildings.

Enclosing the courtyard to create a new dynamic public space was key to the project and Integral produced a variety of options for the roof structure for discussion and costing.

The solutions
Early and ongoing stakeholder liaison was key to establishing the functional requirements and our approach was to open up the floor plates as much as possible to provide flexibility. Investigations were essential to establish the existing structural principles and to inform the solutions. These included archive searches along with visual and intrusive investigations. An ETFE roof supported on slender steel trusses was developed for the courtyard to provide an elegant and cost effective cover to this public space.

County Hall in 2013 won a British Council for Offices award in the Refurbished/Recycled Workplace Category. A national award, the SCALA Civic Building of the Year 2013 Award in the Regeneration category and a LABC West of England award for Best Large Commercial Development.

   Integral's creative and imaginative approach and in-depth sustainability knowledge is invaluable to the County Hall project. They have certainly responded to our brief rather than being constrained by the technical aspects of the project.
