The 2026 Regenerative Architecture Index brings together 119 organisations demonstrating a commitment to regenerative design, delivery and practice.

The Regenerative Architecture Index, created by UK Architects Declare and Architecture Today, recognises practices and built environment organisations working to move beyond reducing harm and towards creating positive outcomes for people, places and the natural world.

Each organisation has submitted detailed responses across the RAI’s three assessment themes: Being a good ancestor, Co-evolving with nature, and Creating a just space for people.

The next stage of the Regenerative Architecture Index will be revealed at the RAI 2026 Launch Party on Thursday 1 October at the Building Centre in London, where this year’s front-runners will be announced.

The event will also mark the opening of Regenerative Design 2026, a month-long exhibition and events programme running throughout October at the Building Centre. Showcasing projects, ideas and approaches from RAI member organisations, the exhibition will provide the first physical home for the Regenerative Architecture Index and offer visitors an opportunity to explore how regenerative thinking is being translated into practice across the built environment.

The Regenerative Architecture Index is also made possible by the generosity, expertise and commitment of its independent assessors. Drawn from leading architectural practices and organisations across the UK, they volunteered their time to review submissions, provide constructive scrutiny and help ensure a robust and transparent assessment process. We extend our thanks to all of the assessors below for their thoughtful contributions and support of the 2026 Regenerative Architecture Index.
