POLICE HQ, WELWYN GARDEN

West Herts Police Headquarters is not a typical demolition project for Tilley and Barrett; however, the high level of constraints and the requirement to demolish substantial structures within a live police facility presented a challenge the team was well prepared to meet.

The removal of significant quantities of asbestos from façade cladding, ductwork, and plant rooms ensured that areas were made safe for soft strip and de-planting activities to proceed.

Throughout the project, both the site and sustainability teams have prioritised circular economy principles, adopting the “three Rs” approach—reuse, repurpose, and recycle. This has resulted in positive outcomes, including the donation of benches and furniture to local organisations for reuse and repurposing.

As works progress, the site team will also collaborate with archaeologists, as the area is of known archaeological interest, with evidence of medieval settlements and Roman activity within the locality.
