The Regenerative Architecture Index began with a necessary change of emphasis. Sustainability had taught architecture to measure damage, reduce consumption and improve performance, but the regenerative argument asks a more searching question: what does a building, a practice or a development actively contribute to the ecological and social systems of which it forms part?
Developed by Architecture Today and UK Architects Declare, the RAI was launched in 2024 to benchmark regenerative policies, actions and working practices. The Index has grown from 68 organisations in its inaugural year to 119 in 2026.
Its assessment is organised around three deliberately expansive themes: being a good ancestor, co-evolving with nature and creating a just space for people.
This matters because regeneration cannot be established through a handful of exemplary buildings. It requires a culture of practice. It needs institutions capable of giving that culture definition, practitioners prepared to test it through their work and forms of representation that allow its ideas to travel.
This is where Architecture Today, UK Architects Declare and the RAI perform related but distinct roles. Architects Declare established the urgency and collective commitment. The Index introduces scrutiny, comparison and a degree of accountability. Architecture Today provides the editorial and cultural framework through which these commitments become visible.
Photography enters this structure at the point where architecture becomes public knowledge. It recognises that photography is not merely a record of architecture. It is part of the infrastructure through which architectural values are distributed.
The Reinventing Practice portrait series extends this enquiry from buildings to the people and organisations producing them. The ongoing series photographs individuals from RAI practices alongside accounts of the work their organisations are undertaking to move towards regenerative practice. Portraiture is important here because regeneration is not an autonomous property of buildings. It is produced through, collaboration, conversation and the development of professional habits.
The portraits give the Index a human register. A practice is encountered through a person: someone making choices, persuading clients, negotiating constraints and attempting to align everyday professional action with a much larger ecological and civic ambition.
Each commission enters a wider cultural network. The images move through Architecture Today, social media, conferences, exhibitions, award submissions, practice websites and teaching. They give the regenerative conversation faces, places and architectural form. They can build confidence among clients and practitioners by showing that regeneration is neither a marginal aesthetic nor an inaccessible technical specialism, but an evolving body of serious professional work.
