What Office S&M does

Office S&M Architects Limited is a London-based RIBA Chartered architectural and interior design practice founded in 2013 by Catrina Stewart and Hugh McEwen. The firm operates as a six-person studio headquartered in Dalston (208 Bradbury Works, N16 8JN) and delivers architectural services across residential projects (homes, housing, retrofit), commercial workspace fit-outs, educational settings (nurseries, schools, SEND provisions), and public-realm regeneration. Core technical offerings include feasibility studies, planning applications, design development, and project management, underpinned by a proprietary "Deep Listening" community engagement methodology for public clients and a sustainability approach emphasising natural/recycled materials and low-embodied-carbon construction.

The practice serves five primary customer segments — individual homeowners, property developers, local authorities/councils, education clients, and commercial clients — with a stated 50/50 split between public and private engagements. Notable council relationships span one-third of all London boroughs, with repeat work for Newham, Islington, and Haringey, and twenty high-street regeneration projects delivered. Pricing is quote-based per engagement, with project investment levels ranging from £150,000 to over £5 million. Revenue is generated entirely through professional design fees under multi-year project contracts, with go-to-market driven by word-of-mouth referrals, press coverage in publications such as The Guardian and Dezeen, and a strong industry-award track record including BD Young Architect of the Year 2020 and RIBAJ Rising Stars 2019.

The firm holds memberships in five UK public-sector procurement frameworks (Bloom, Perfect Circle, Be First DPS, London Construction Programme, and LHC), and co-founders sit on five statutory Design Review Panels (Hackney, Tower Hamlets, Haringey, Croydon, Essex) plus the Design Council. Approved schemes are cited as exemplars in Croydon, Tower Hamlets, and Lewisham small-sites planning policy. Geographic delivery has expanded beyond London to Kent, Bedfordshire, East Sussex, Greater Manchester, and Berkshire, while the practice has no external investors, subsidiaries, or parent company, operating as a wholly founder-owned private limited company.
