Graham set up the Somerset office of Prewett Bizley Architects in 2013.  Before moving to the west country he sat on the Hackney Design Review Panel and on the Islington Conservation and Design Panel.   

Graham has written regularly for various architectural journals, including a bi-weekly ‘In Detail’ feature for Building Design presenting the construction of a recently completed building with a 3-dimensional detail drawing. He is the author of two books on architectural detailing based on these studies which are published by the Architectural Press and is currently working on a book on Rural Architecture.  He lectures widely on the work of the practice and is a part-time teaching fellow at the University of Bath.

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. At Panter Hudspith Architects he was project architect on several large mixed use urban regeneration projects on constrained sites, involving multiple listed buildings in historically sensitive city-centre locations in York, Leeds and London.


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.  At Feilden Clegg Bradley, Robert was responsible for design and implementation of a 110 bedroom student hall of residence for Queen Mary’s University that won a Housing Design Award in 2005.
