About the practice

William Tozer Associates is an award-winning practice based in London. Founded in 2002, our practice has broad experience, including in standalone residential properties, housing, office, retail, and hospitality sectors, and we have worked on projects in the UK and internationally. Each of our projects delivers our clients’ aims and aspirations, while also creating a building and interiors that are compositions of sculptural form and space—walls, floors, ceilings, and storage expressed as abstract planes and volumes. While being ever-conscious of environmental performance and impacts, our projects also curate and re-frame the context and history of each site. We revel in the processes of writing, drawing, model-making, demolition, construction, and photography, and attempt to capture in the finished building the delightful open-endedness of these processes of making architecture. This results in buildings with open-plan spaces, frameless openings, and raw material finishes. Alongside our work in other sectors and locations, we have developed a particular specialism in designing house extensions across almost every borough of London. Our designs for rear extensions, loft extensions, basements, and renovations have transformed the way our clients inhabit their homes.
