Transforming a Grade II listed mansion into modern office workspace

Corsham Digital Mansion Redevelopment and Conversion

Working under the professional services partnering framework, we provided structural and civil engineering and transportation assessment services to Wiltshire Council to help deliver the transformation and redevelopment of the historic Grade II listed Corsham Mansion House. The vision for the project was developed by Wiltshire Council and Swindon and Wiltshire Local Enterprise Partnership (SWLEP) working together with Corsham Institute and Bath Spa University.

Our transport team produced a transportation statement and travel plan for submission to Wiltshire Council as part of the planning application. This included supporting the sustainable location of the site and providing vehicle swept path analysis to inform the site layout and waste collection strategy. We worked closely with the local highway authority to address their concerns and amend aspects of the design.

We produced the structural designs for the modern two-story extension and new entrance lobby. Collaborating with DK Architects and a specialist stone mason, we developed the structural solution to facilitate the striking two-story glazed corridor link, which connects the historic listed building with the modern office accommodation. Strengthening the existing stone framed windows enabled the removal of the central mullions at both ground and first floor levels, creating generous wheelchair accessible openings from the extension into the existing mansion house.

Following surveys using CCTV, which identified several defects, our civil engineering team incorporated improvements to the existing drainage system to the mansion house. We developed coordinated designs with the project team for new storm drains and foul network. The existing car park surface was re-profiled, delivering a useable area free of hazards.

The redevelopment of Corsham Mansion House creates an incubation space for businesses working within the digital and innovation sectors, as well as teaching space to deliver related education courses and facilities for the community, industry, institutions, academia, and the public sector.
