Office S&M elevate the everyday. Established by Catrina Stewart and Hugh McEwen in 2013, Office S&M is an award-winning architecture practice working with a 50:50 split of public clients and private clients on individual homes, new-build housing, workspace retrofit and public realm projects. 

The practice engages clients and users in a collaborative process, experimenting with colours and materials to deliver joyful and unexpected private spaces and public places. Office S&M responds to the context of each project – house, street or neighbourhood – acknowledging the existing, while deploying colour and narrative inventively to create drama.

Built projects include: Valetta House (2017), which won the NLA Don't Move, Improve! 2018 'Best use of materials' award; Salmen House (2017); Janus House (2018); and Finsbury Park High Street shops (2017), all in London. Current projects include: The Earth House, a newbuild house in East Sussex; The Green Room and Cafe in Newham; Nag’s Head Market, Holloway; and Chipstead Way, Croydon.

Achievements to date include: winning Building Design’s Young Architect of the Year Award (2020); inclusion in The Architects’ Journal’s 40 under 40 - a showcase of architecture’s brightest up-and-coming talent (2020); and recognition as a Rising Star by RIBA Journal (2019). Office S&M feature in The Architecture Foundation’s New Architects 4, published in 2021.

‘Office S&M is certainly one to watch.’

Catrina Stewart
Catrina is a registered architect who trained at The Bartlett School of Architecture, UCL. She established Office S&M with Hugh McEwen in 2013, with whom she has taught at Oxford Brookes University and The Bartlett, UCL.

Catrina has extensive experience delivering projects that bridge public realm and private enterprise. Her specialism in activating public spaces, community engagement and co-design is reflected in her role leading on public and educational projects for local authorities and private businesses. Catrina’s prior experience, developing a BAFTA Award-winning handmade computer game, Lumino City, and working in the family toymaking business, have given her a deep understanding of how best to engage with communities, what makes public spaces thrive, and the challenges involved.

Catrina’s role at Office S&M has included delivering award winning residential, workspace and retail projects with extensive expertise in green and sustainable design. She combines excellent design ability with sound knowledge of planning and regulatory standards to deliver projects on sensitive sites. 

As a recognised leader in her field, Catrina has been appointed as a Design Council Expert where she advises the government and local authorities on the values and benefits of good design. Catrina is an external examiner at Arts University Bournemouth, and has lectured internationally including, the Royal Academy of Arts, the V&A, UCL and Cambridge University.

Hugh McEwen
Hugh is a registered architect who trained at The Bartlett School of Architecture, UCL, and University of Nottingham. He established Office S&M with Catrina Stewart in 2013, with whom he has taught at Oxford Brookes University and The Bartlett, UCL.

Hugh previously worked for a range of housing specialists, most notably Pollard Thomas Edwards and Metropolitan Workshop, where he gained significant experience that has allowed Office S&M to successfully deliver its ambitious projects. As a partner at Office S&M, Hugh has led on the widely published Salmen House, Putnoe House, and Janus House, and has recently moved onto larger projects, including multi-unit residential schemes in Croydon, Bromley, and Kent.

Hugh’s role at Office S&M includes leading on collaboration and contacts with architectural teams; overseeing compliance and best practice in residential design; and providing policy advice on infill housing around London. He specialises in delivering projects and engagement that crosses between private and public realms, having led on the work for several high street regeneration projects, and worked on market renovations in Newham, Ilford, and Islington.

He has written for Building Design, Blueprint, and the Architectural Review, and his drawings have been exhibited at the Royal Academy Summer Show. Hugh’s expertise has led to him being selected for the Newham Design Review Panel, the Essex Quality Review Panel, and he was named as a winner of the 2019 RIBA Journal Rising Stars for his work at Office S&M.
