Working from studios in London and Wells in Somerset, we are a team of architects committed to radically reducing the impact of buildings on the environment.  Having pioneered some of the most ambitious retrofit and Passivhaus projects we push the boundaries of low-energy and low-carbon construction to create buildings that are robust, joyful and sustainable.

By establishing an open and creative dialogue with our clients we seek to make engaging, atmospheric environments that enhance people’s daily lives. We try to observe the nature of places to understand their qualities, patterns and nuances.  We propose interventions that might intensify the sense of place, healing and providing continuity with the existing context.

We give practical and useful advice that enables our clients to understand the design process and make informed decisions.  We are committed to achieving best value for our clients through thoughtful design.  We offer consultancy services to building owners and other professionals on Retrofit, low-energy and low-carbon construction, and have coauthored important guidance on these subjects including PAS 2035, the British Standard for Retrofitting dwellings.  

Our architectural work is rooted in the wider activities of teaching, writing and research which allow us to combine thought and technical innovation with a practical approach to the realities of development and construction.  We have a hands-on approach through which we continuously seek to improve the quality of construction on site.

Our work has been recognised by a number of awards, including the Mews House Deep Retrofit which won an RIBA Award in 2022, and the Dundon Passivhaus in Somerset which won RIBA Regional and National Awards and was a finalist for the prestigious Stephen Lawrence Prize. We were winners of the BD Sustainability Architect of the Year Award 2017.

We work closely with Interior Designer Emily Bizley and can offer a fully integrated service incorporating architecture, interior design and energy analysis.

 

How we work 

The posts below from our Journal talk about the way we work and how we think about architecture.

GRAHAM BIZLEY BSC(HONS) BARCH ARB RIBA - DIRECTOR

Graham set up the Somerset office of Prewett Bizley Architects in 2013.  Following his move to Somerset Graham began researching the British landscape. He is particularly interested in what the landscape means to different people and how we can build in the countryside in a way that is sustainable and enhances a sense of place.  He submitted a proposal on rural architecture for the British Pavilion at the 2014 Venice Biennale and was one of 4 shortlisted teams.

Graham has written regularly for various architecture journals and is the author of two books on architectural detailing published by the Architectural Press. He is currently working on a book on Rural Architecture.  Graham has lectured widely on the work of the practice at UK universities, is a part-time teaching fellow at the University of Bath and an external examiner at the Arts University Bournemouth.  He is a judge on the RIBA, AJ Sustainability, AJ Retrofit and AJ100 Awards. He sits on the Design West Review Panel, and previously on the Hackney Design Review Panel and on the Islington Conservation and Design Panel.   

Graham studied at Bath University and the ESTAB in Barcelona. Prior to establishing Prewett Bizley Architects he worked for practices in the UK, India and Zimbabwe.

ROBERT PREWETT BSC(HONS) MARCH ARB RIBA - DIRECTOR

Robert heads the London office of Prewett Bizley Architects and has developed considerable expertise in low-carbon construction, particularly in the field of retrofit. He is a certified Passivhaus designer and has presented a number of ground breaking retrofit projects at Passivhaus conferences, RIBA CPD events and the award winning Retrofit Coordinator course.

Robert is a member of the RIBA Sustainable Futures Group which advises the profession and government on the incorporation of sustainability in education, standards and policy. He is a founder member of the Passivhaus Trust and a technical advisor to the STBa (Sustainable Traditional Buildings Alliance). He has previously been a trustee of the charity RESET that aimed to deliver training and knowledge sharing to increase resilience within our built environment, particularly in areas facing severe climate change impacts.

From 2007-11 Robert was Course Coordinator for Construction and ran a Diploma level design studio at the University of Greenwich. He studied at Bath University and the Technische Universiteit in Delft. Before setting up practice with Graham Bizley he worked in the UK, Belgium and the Netherlands.
