What justice architects have to balance that other sectors simply don’t

In most sectors, safety and human dignity work in the same direction. In justice facilities, they can pull against each other, and resolving that tension is central to the design process.

Detention centres, for instance, must meet strict security requirements. Sightlines, materials, circulation and technology all need to support staff in managing risk. Yet security measures that feel purely punitive can undermine the very outcomes the justice system is meant to achieve.

This is where the expertise of justice architects becomes essential. As Steven Lennon, HLM’s Head of Justice & Emergency Services, describes it, ‘our approach is operationally led, ensuring every building supports efficiency, safety and wellbeing together’.

Designing spaces that are secure without feeling dehumanising means paying close attention to light, scale, acoustics and material choice, aspects of design that might seem secondary elsewhere but are fundamental here. Getting this balance right protects both residents and staff, while supporting the rehabilitation the wider system depends on.

Few sectors carry the mental health burden that justice architecture must respond to. Many residents within the criminal justice system live with mental health conditions, trauma or histories that intersect closely with healthcare needs.

This is why mental health care and justice design are so closely linked. Programme spaces for treatment, counselling and education need to sit comfortably alongside secure environments, supporting healing rather than simply containment.

Restorative justice principles are increasingly shaping how these environments are conceived. Rather than designing purely for incarceration, we focus on how buildings can support successful reintegration, helping residents build the skills, relationships and stability needed for life beyond the facility.

A wellbeing-focused approach to justice design recognises that reducing recidivism starts with the everyday experience of the space itself.

Justice buildings don’t exist in isolation. They sit within neighbourhoods, serve families, and shape how a community understands safety and fairness.

Community engagement is therefore a core part of any responsible design process. Listening to residents, local leaders and government stakeholders early helps establish trust and ensures facilities respond to the reality of the place they serve, rather than working against it.

This is particularly true for courts and courthouses, where public confidence in the justice system depends partly on the building itself. HLM’s Southern Justice Courts project is a good example of this, bringing police, magistrate and crown courts, custody facilities and justice agencies together within one interconnected building, and helping the transition from public to private space feel calm rather than intimidating. A courthouse that feels transparent, accessible and calm can make a genuinely positive difference to how people experience the justice process, whether they are visiting as a juror, a family member or a defendant.

Creating facilities that support these wider services, from legal aid and family support to counselling and reintegration programmes, means thinking beyond the courtroom or cell itself. It means understanding how a whole campus of spaces works together to serve the people who pass through it.

Justice architecture is a field where informed decisions matter enormously, and where evidence-led practices are increasingly at the forefront of the profession.

Technology and construction method both play a growing role in supporting safety, efficiency and better outcomes across justice facilities. At HMP Five Wells, our design and construction teams used offsite manufacturing to deliver a build almost 22% faster, with 80% standardised components, while our approach to design for rehabilitation has driven innovations, such as barless windows, that maintain security while giving residents a genuine connection to daylight and sky.

At HLM, we draw on decades of experience and a deep well of resources to assist clients through every stage of these projects, from early vision through to completion. Our history working across health, education and justice sectors gives us a distinctive vantage point: we understand how architecture can support treatment, training and rehabilitation, not just accommodate it.

Designing justice facilities carries a responsibility that few other building types ask of their designers. Get it right, and architecture can genuinely assist successful reintegration, support families, and help reduce recidivism across a whole system. Get it wrong, and buildings can quietly work against the very outcomes government departments and communities are hoping for.

This is what sets justice architects apart. Every solution shapes how people experience some of the most difficult moments of their lives, and how they might move beyond them. Experts across the wider profession have pointed to international exemplars where staff ratios, connection to family and calm, considered spaces all contribute to better outcomes, a reminder of just how much influence architecture can have over rehabilitation when given the chance.

At HLM, this responsibility sits at the heart of our mission. We believe good design can support human dignity at every stage of the justice system, from courthouse to detention centre to community reintegration, and that thoughtful architecture has real influence over people’s futures.

The future of justice architecture will be shaped by the same forces reshaping every part of our built environment: a deeper focus on wellbeing, a stronger commitment to sustainability, and closer collaboration between designers, clinicians, government leaders and the communities these facilities serve.

As our understanding of mental health, restorative justice and rehabilitation continues to grow, so too will the expectations placed on justice facilities. We remain committed to helping clients navigate this complexity, bringing our full expertise to justice projects that support safety, dignity and hope in equal measure.

If you are exploring a justice, courthouse or detention facility project, our team would be pleased to support you in establishing a considered, evidence-led design process.
