We are Transition by Design, an RIBA chartered and Passivhaus certified architecture and design cooperative based in Oxford. Our team builds homes, neighbourhoods and cities for an ecologically sustainable and convivial future.

We specialise in ecological architecture, community engagement, citizen-led and participatory design, action research, meanwhile use, and community-led housing. As a workers’ cooperative, we operate democratically—reinvesting profits into our team, our community, and projects that align with our values.

If you’ve got a project in mind, please get in touch. We’d love to hear from you.
