Custody and Justice

It’s safe to say we know a thing or two about operating within the complex and uniquely challenging custody and justice sector. Our designs combine innovative and sustainable building solutions with the safety and security that is paramount.

Fully compliant with MOJ guidelines

Our engineers are experienced in this technically challenging environment where safety and security are key. Our highly experienced design team operate with an in depth knowledge and understanding of both the technicalities and intent of Ministry of Justice design processes and guidance. In fact, we were invited to act as consultants to develop the new MOJ Design System.

Custody Suite

Innovative and sustainable design 

We are constantly seeking solutions to improve the sustainability of our designs – and the custody and justice sector is no exception. Our custody suites include innovations in system design and de-carbonised energy solutions to create modern, sustainable buildings that maintain the necessary level of security. In conjunction with our project partners, we constantly challenge established approaches to seek betterment in buildability, cost effectiveness and sustainability, with the optimum solutions combining all three.

Trusted to deliver safe and secure solutions

In partnership with Willmott Dixon, we have developed a sustainable, repeatable skeleton design, allowing us to create a custody suite for a set budget that meets the needs of modern-day policing.

We also work directly with the SCAPE and CODE frameworks, giving you the confidence that you are working with a trusted and talented team.
