About us

51% Studios is an AIA & RIBA award winning London based practice providing a full range of architectural and urban design services. We have considerable experience working in historic and listed environments, on sites of special scientific interest and areas of outstanding natural beauty, both in the UK and abroad. We work with artists and organisations, as well as private clients. We also work with wildlife.

We aim to deliver excellence through our close attention to detail and collaborative, iterative working practice, often with large consultant teams. Clients, fellow consultants and end users work as part of the design team to ensure the final product is beautiful, efficient and fit for purpose.

As stewards of the natural environment and our client’s resources, we are committed to creating thoughtful and responsible buildings. We deliver highly crafted solutions on time and on budget and are known for providing innovative solutions where budgets are tight or sites constrained. We shape each project with empirical environmental knowledge and energy modeling resulting in sustainable strategies that artfully respond to each site’s unique character.

Our projects often take non standard forms and have diverse teams. Clients choose us because they require the high degree of lateral thinking that we can bring to any project.

“51% studios has worked on a diverse range of architectural projects, each managed to a high creative standard.  The practice’s perception of what can be achieved in response to a brief is highly imaginative.  A responsive interest in the possibilities of existing building and a readiness to think long-term, including environmentally, are key aspects of the firm’s ethos.” The Architecture Foundation
