The Constructivist Regenerative Design Lab supports the transition to a regenerative built environment. Through our eight-month programme leaders and future leaders explore the principles of regenerative design and experiment with applying them in practice.
This is a learning journey that is both explorative and transformative. We create a community of change-makers and give them the tools to make change.
Our journey so far
Since 2022, four cohorts of the Lab have explored regenerative deisgn in practice. Participants have come from across the built-environment — engineers, architects, policy-makers, local authorities and educators. Along the way we’ve:
Developed a robust methodology and regenerative design toolset.
Published The Pattern Book for Regenerative Design and The Regenerative Structural Engineer.
Built an alumni community that is continuing to shape practice in their organisations and projects.
An eight-month immersive programme for leaders and future leaders across the built environment
who are ready to put regenerative thinking into practice.
Since launching in 2022, the Lab has welcomed over 70 participants, seeded
The Regenerative Structural Engineer and
The Pattern Book for Regenerative Design, and built a growing alumni network shaping
practice across engineering, architecture and policy.
Cohort 6 is your chance to join this movement — to test regenerative design in your own
projects, develop new approaches for your organisation, and connect with a powerful community
of change-makers.

In 2025-2026, we are running three cohorts:
Cohort 5: Hazel Hill Lab — an internal Lab for Hazel Hill Trust staff and trustees. Not open for applications, but an important demonstration of how the Lab can work for site-specific teams.
Cohort 6: Open Lab — our core programme for professionals across the built environment. Applications are now closed. Read more about this cohort.
Cohort 7: Alumni Lab — a new programme designed for those who have already been through the Lab and want to deepen their practice. Runs Spring to Autumn 2026. Register your interest in Cohort 7
What to expect
Over 8 months, five online workshops and three residential gatherings at Hazel Hill Wood, you will:
Unpack the principles of regenerative design
Apply them to a live project or workplace challenge
Explore how regenerative practice can shape your own life and work
Reflect on the impact of your experiments with a supportive peer group
Our programmes are rooted in peer-support and practical, action-learning, blended with expert facilitation.
Hazel Hill Wood — an off-grid learning centre near Salisbury — is our hearth for the journey. Returning there three times over the programme, we connect with the forest ecosystem as both a teacher and a mirror for our work.
What you bring and what you get
What you bring
