ince our inception in 2008 Hewitt Studios has determinedly pursued an accessible and design-led approach to sustainable architecture. Working through a recession in which sustainability was widely perceived as an unaffordable ‘extra’, we have sought to place it fundamentally at the heart of each of our projects – creating outcomes (and value) that wouldn’t have been possible without this impetus; leverage additional funding (Straw Bale Cafe), achieving difficult planning permissions (Limpley Stoke Eco House), underwriting business plans (The Arts Space), reinvigorating brownfield sites (Ralph Allen Yard) and creating inspirational and educational spaces (all of the above).


Our definition of a sustainable project is holistic – the economic and social viability of a project is of equal importance to its environmental credentials. This is why something like the Straw Bale Cafe (designed in-conjunction with academia, built by the end users, using local carbon-sequestering materials and for the benefit of their own community) typifies our approach – its not about box ticking, its about collaboration – getting everyone onboard to create a truly sustainable and fully-considered outcome.

Nevertheless, we are happy to work within recognised standards when required and we have delivered buildings to BREEAM and C4SH 5 (zero-carbon) levels.


As a result, our projects have attracted widespread interest (on websites like ArchDaily, DesignBoom, Domus & Tree Hugger) as well as multiple plaudits (such as 4no. Green Apple Sustainability Awards) for their green credentials.


We have worked BathNES Bath Green Homes initiative to promote awareness of the technology and rationale which has made Ralph Allen Yard a benchmark zero-carbon development.


Most recently we have developed a model for a sustainable transport and smart cities hub and we are working with GoUltraLow on its first implementation in the South West.


In December 2014 we were named the UK’s ‘Sustainable Architect of the Year’ for our pioneering work across the sector.
