Quartet Architecture is a Royal Institute of British Architects (RIBA) chartered practice, specialising in the design and delivery of bespoke residential architecture across London and the surrounding areas. With over 25 years of experience and more than 75 years of collective expertise within our team of architects and architectural technicians, we offer a full range of architectural services, from contemporary house extensions to large-scale new builds.

As established architects in Wandsworth, we are ideally located to serve clients throughout South West London, including areas such as Clapham, Battersea, Wimbledon, Putney, and beyond. Our extensive knowledge of planning regulations, combined with a passion for thoughtful, creative design, allows us to maximise every opportunity and add long-term value to your home.

We pride ourselves on producing innovative, context-driven design schemes tailored to our clients’ needs. Our architecture is both aesthetically striking and highly functional, always grounded in a deep understanding of the brief, the site, and the people who will live in the space. We believe every home should reflect the personality, lifestyle, and aspirations of its occupants.

Whether you’re considering a kitchen extension, a basement conversion, or a complete house renovation, our collaborative approach ensures that your vision becomes a reality. If you're planning a residential project and need experienced London architects, we'd love to help bring your ideas to life.
