This semi-detached home in Surrey called upon Russian For Fish to unify its existing rear conservatory and detached garage. The brief was to transform them into a modern, monolithic, L-shaped extension that would create a striking but attractive contrast with the 19th-century architecture of the house. The conservatory was replaced and the garage converted, forming a single zinc-clad structure that enlarged the kitchen, provided additional living space, and housed a bright garden studio. Zinc was chosen for its low-maintenance qualities and its suitability to the timber frame, as well as its aesthetic relationship with the minimalist grey-white palette of the interiors. Given the untraditional appearance of the extension, the project required extensive negotiations in planning, but Russian For Fish were able to secure permissions on appeal, resulting in a practical space, a visually arresting structure with a simple and singular material form.
