Duncan is a practicing architect, academic and environmental activist. Author of ‘The Re-Use Atlas: a designer’s guide towards a circular economy’ published by RIBA, he has practised, researched, and taught around issues of sustainable development and closed-looped systems for more than 25 years. He recently founded BakerBrown, a research-led architectural practice and consultancy created to address the huge demands presented by the climate and ecological emergency as well as the challenges of designing in a post-COVID world. Over the years Duncan’s practices (and academic ‘live’ projects) have won numerous accolades including RIBA National Awards and a special award from The Stephen Lawrence Prize for the Brighton Waste House - the prize money has since been used to set up a student prize for circular, closed loop design at the University of Brighton where Duncan teaches.

Duncan has worked on projects as diverse as 'The Greenwich Millennium Village' in London, the RIBA’s ‘House of the Future’, the multi-award-winning ‘Brighton Waste House’ and recently he designed a new building for Glyndebourne Opera that will be constructed from waste flows and organic materials grown on site. Duncan is currently working on schemes for Net-Zero Carbon social housing with Brighton & Hove City Council, where he has recently lead on drafting of their recently published Circular Economy Route Map.
