Exceptional award-winning design

Pioneers in Passivhaus and low energy retrofit


We are looking for a creative and technically proficient part II architectural assistant and a part III qualified architect to work in our Somerset studio. Please see our Employment Opportunities page for details.


Working from studios in London and Wells in Somerset, Prewett Bizley Architects produce inspiring, energy-efficient buildings with a sensitive approach to context. Through a creative dialogue with our clients we seek to create engaging, atmospheric spaces that are a pleasure to use, responsive to needs of their users and that bring lasting improvements to the quality of people’s lives.

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 according to their particular needs. We try to observe the nature of places to understand their qualities, patterns and nuances in order to propose interventions that might heal or provide continuity with the existing context.

Having pioneered some of the most extreme low-energy retrofit projects to date in the UK we are passionate about the need to reduce the impact of buildings on the environment. We are part of the 15:40 Collective of architecture practices that share a commitment to radically reducing the energy consumption of buildings through a 'fabric first' approach, with extensive experience in delivering sustainable new-build and retrofit projects using Passivhaus construction methodologies. We offer consultancy services to building owners and other professionals on low-energy construction and Passivhaus design. We have a hands-on approach through which we continuously seek to improve the quality of construction on site.

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. Current research focuses on rural architecture, self-build housing and how the principles of low-energy construction can be applied to retrofit of listed buildings. Please see our Journal for more information.  Our work has been recognised by a number of awards, most recently the Dundon Passivhaus in Somerset which won RIBA Regional and National Awards and was a finalist for the prestigious Stephen Lawrence Prize. We are winners of the 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.  We work throughout the south of England with recent projects in Devon, Somerset, Dorset, Wiltshire, Oxfordshire, Berkshire, Surrey, Sussex, Kent and London.
