Secure Environments
We design, build and maintain prison spaces, with security-cleared teams working around the live regime.
Trusted by the Ministry of Justice and HM Prison Service
Delivered by Parogon
Built inside the wire.
In a prison, the regime comes first. Every person, vehicle, tool and delivery is controlled, and the works have to fit around movement, association and lock-down. We plan around that from the first drawing.
For over 20 years Parogon has delivered for the Ministry of Justice and HM Prison Service: security improvements, fire regulation works, secure fit-out, new buildings and modular units, and maintenance behind the gate. Our teams are cleared to EL1 or higher, and every package is built to MoJ standards with certified handover.

Why Parogon
We design, build and maintain. No hand-offs between contractors, so nothing gets lost.
You sign off one complete drawing. That drawing is what gets built, to an agreed cost and programme.

Deep dive
The establishment's routine sets the programme. We plan access, deliveries and sequencing with them before work starts.

Deep dive
Older estates carry decades of penetrations, alterations and tired doors. We survey, fire-stop, compartment and certify.

Deep dive
Detailing for custodial and mental health settings, specified from the first drawing. HMP Bronzefield's Mental Health Unit shows how it comes together.

Deep dive
Rehabilitation needs real settings. At Wormwood Scrubs we delivered Fred Sirieix's vision for The Right Course: a coffee shop and table-service restaurant where prisoners train in hospitality for work on release, with a full fit-out including M&E, inside an operational prison.
