This issue is dedicated to the Regenerative Architecture Index 2025. Launched a year ago by Architecture Today and Architects Declare UK, the RAI has taken on a life of its own. While there were 64 practices in the inaugural RAI, there are 116 organisations on this year’s list: architectural practices of every size, plus a smattering of landscape architects and engineers.
We are enormously grateful to Architects Declare for dedicating so much time to the herculean task of assessing and debating the submissions. And to Broadway Malyan for hosting the 2025 RAI party at its studios; Camlins Landscape Architects for supplying the booze; and Schüco, who have come on board as RAI partners for 2025 and 2026.
Perhaps most of all, we are grateful to the clients who have recognised the RAI as a means of fraternising with like-minded practitioners, swapping knowledge and ideas and – crucially – identifying architects who share their values and are ready and able to help them to realise their vision.
Wildheart Trust CEO Lawrence Bates spoke at the inaugural RAI party, outlining his then nascent plans for an International School
of Rewilding and Regenerative Agriculture (ISORaRA) at Sandown on the Isle of Wight. A few months later he invited RAI practices to submit Expressions of Interest to join the design team for the school. He announces the shortlist – and the thinking behind the selection panel’s decisions – on page 72.
Neuroscientist and educator Beau Lotto took this year’s RAI party as an opportunity to share his thinking about the transition to a regenerative future, and to unveil his vision for a school designed to engender a symbiotic relationship with the wider community and the natural world. RAI practices will be invited to submit Expressions
of Interest later in the year.
The dream is that the RAI becomes, not just a professional community, but a nuanced ecosystem with the vision, skills and resources to create a better world.
