Unashamedly ambitious. Creating better places. Having fun along the way.


IF_DO was founded in 2014 by three good friends, bored by inaction and excited by the possibility of doing things differently.

We believe architecture has the power to improve lives and make communities happier and stronger. We have a knack for building relationships, exceeding expectations and delivering projects with people at their heart. 

We won the first competition we entered, The Dulwich Pavilion, and its success led to work across Education, Arts, Community, Workspace and Housing. 

We are a close team who hold each other to the highest standards. Our growing reputation is for well loved and thoughtful work. 


Al Scott

MA (Hons) DipArch (Dist) ARB RIBA — Director

Al combines the perfect balance of imagination and pragmatism, and he’s fascinated by the path from one to the other, or – in more architectural terms – from initial sketch to finished building. For him, the craft and ‘buildability’ of architecture is crucial, and he led the delivery of the Dulwich Pavilion, the project that has perhaps done the most to show what we are capable of when we bring conceptual thought and technical ability together. But for Al the real success of the project lies in the impact it’s had on everyone who’s visited, and the positive contribution it’s made to the community.

Al is committed to increasing the socio-economic diversity of our profession. He is an RIBA mentor to architecture students and is involved with the Stephen Lawrence Charitable Trust and the Social Mobility Foundation, helping create more opportunities for young people from all backgrounds.

Sarah Castle

MA (Hons) MArch (Dist) ARB RIBA — Director

Sarah is a firm believer in collaboration – amongst colleagues, with clients, with stakeholders, and with the people who will be enjoying our buildings for years to come. She’s brilliant at finding a way through competing interests to come up with a design that works for everyone, and this kind of determined diplomacy was one of the key ingredients in the transformation of a dilapidated structure near Waterloo Station into a vibrant community hub.

Sarah feels strongly about sharing our knowledge and experience beyond the practice, and she has taught at both the University of Brighton and the London School of Architecture. She is a chapter leader for Urbanistas, a women-led network devoted to supporting and encouraging women working in the built environment, and is passionate about the need to make architecture a more diverse and equal profession.

Thomas Bryans

MA (Hons) MArch (Harvard) ARB RIBA — Director

Thomas is a big-picture thinker and masterplanner by nature. He has a wide-angle view on every element of our work and sees connections that might not be immediately obvious. He’s also a great communicator – both in person and on the page – and his TEDx Talk on ‘Architecture’s Ripple Effect’ is the perfect introduction to how we think and work.

This interest in the wider repercussions of architecture goes hand in hand with an interest in sustainability and creating healthy environments. He’s drawn to working on projects where IF_DO can make a positive and far-reaching impact. He was the driving force in making our work at St Teresa’s School so rewarding, both for us and for the school, by involving the students in reshaping their school for the better, and inspiring them with what architecture can do.
