Office S&M is an award-winning, RIBA Chartered architecture practice founded and directed by Catrina Stewart and Hugh McEwen. Based in London, the architects and their team create experiences through architecture, telling a story through each building they design.
Office S&M works with both private and public clients, on a variety of projects ranging from new-build housing to public realm projects and workspace retrofits. The practice provides a full range of architectural services to assist you throughout each stage of your project, from design and planning to tenders and construction management. 

The architects and their team go on a design journey with each of their clients, arriving at a personalised project that neither you nor they could have imagined before working together. Placing collaboration at the heart of their work, the architecture practice brings a multifaceted skillset that enhances each of their projects, whether public or private.
Office S&M has been recognised for their inventive, joyful designs with numerous awards, notably named RIBAJ Rising Star in 2019 and Young Architect of the Year Award Finalist in 2020. Finding opportunities where others see obstacles, the architects adopt an experimental approach and innovate through their use of colour and materials.
