PLATFORM PRISON DESIGN AND BUILD PCE’s Secure Prison solution, fully compliant with Home Office and NOMS design guides, ensures safe, high-quality, and efficient prison construction with predictable outcomes. This scalable platform DfMA approach leverages repeatable designs and standardised, offsite-manufactured components, each cast with essential security, M&E, and utility integrations to optimise quality. These pre-engineered components form a ‘Kit of Parts’, quickly assembled onsite to create a robust, monolithic structure with superior acoustic, thermal, and fireresistant properties. By assessing embodied carbon from stages A1-A5, the solution also minimises environmental impact throughout the structural delivery phases. Secure Prison has become the benchmark for success across the UK prison estate, with PCE handing over circa 7,000 prison places across multiple prisons, including HMP Five Wells, HMP Fosse Way, and HMP Millsike.
