The front-runners for the RAI2026 were announced by Mandy Franz, Tom Gibson and Rory Thomas of UK Architects Declare on Thursday October 1st at the launch party for Regenerative Design 2026 at the Building Centre in central London.

Run by Architecture Today with UK Architects Declare and delivered in partnership with Schüco, the RAI benchmarks the progress of practices moving towards regenerative design and delivery, recognising the need for a built environment that goes beyond reducing negative impacts to generate positive outcomes for both the present and future. Now in its third year, the 2026 Index comprises 119 organisations, ranging from sole practitioners to multidisciplinary global practices.

Each organisation submitted detailed responses across three interconnected pillars: Being a good ancestor, Co-evolving with nature, and Creating a just space for people. Submissions were independently assessed through UK Architects Declare, with particularly engaging or insightful responses identified as front runners alongside runners-up and ones to watch.

Responses from the front runners, together with wider thinking, projects and conversations emerging from this year’s Index, are brought together in a special Regenerative Architecture Index issue of Architecture Today (AT345).

Regenerative Design 2026

Launched by Architecture Today, RD26 is a month-long programme of exhibitions and events designed to communicate the principles of regenerative design to a broad audience of architects, clients, consultants, contractors, policymakers, sustainability leaders and the general public. It also serves as the first physical, albeit temporary home, of the Regenerative Architecture Index, a partnership between Architecture Today, UK Architects Declare and RAI partner Schüco.
