Every project starts with a question—What if?

What if the places in which we live and work could make us healthier and happier?—Improving lives through better design. What if we could create beautiful buildings that work for the environment as well as for us?—Cleaning the air we breathe and generating more energy than they use. What if we could make spaces that everyone could enjoy?—Creating diverse and inclusive environments. What if we designed our cities for people to cherish and develop the places in which they live?—Building a better future for generations to come.

What if we worked to achieve all of this?—We do.

We’re idealists. We came together as three young architects to set up IF_DO in 2014, and we saw no end to the possibilities. We chose our name because it said something about the power we have, as architects, to do things differently.

Since then, we’ve worked closely with clients and communities who share our aspirations. We’ve forged positive relationships across the industry, and we’ve been rewarded with responsibility and trust. And, with projects like the Dulwich Pavilion and St Teresa’s School, we’ve shown how imaginative architecture can begin to shape people’s lives.

It’s not just the three of us around the table now, and our stage is bigger. We have a team of carefully chosen and like-minded colleagues. We’ve built up an impressive track record. We’ve won competitions and awards to show we can compete amongst the best. And with our clients and collaborators, we’ve begun changing the world, project by project.

We’re quick to get down to detailed analysis and research. We question, test, explore and imagine. We sketch and make models. We’re happiest developing our ideas alongside ambitious clients, and we work collaboratively and openly. We listen to communities to make sure we understand what they need and what will work best for them. We make everyone a part of the process.

It’s a pragmatic and pro-active way of working which sits well with our idealism; we’re improving people’s lives through better design. We’ve lost none of the hope and determination we had at the start, and our conversations – with each other and with our clients – are as full of energy as they were on that first day. We know, more than ever, that buildings can do so much.

We call this ‘the ripple effect’, and it’s at the heart of our approach. Thomas’s TEDx talk back in 2017 put this into words we all stand behind: ‘Buildings have ripple effects. Buildings affect the communities around them, they affect the economy, and they impact the environment.’ In short, we take our responsibilities as architects seriously.

People often ask us about our name, and we enjoy telling the story of how it came about. Those two short words express our hopes for the future and our purpose. They’re a reminder of how we began and where we’re headed. What if? We do.

Thomas Bryans

MA (Hons) M.Arch (Harvard) 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.    


Sarah Castle

MA (Hons) M.Arch (Dist) 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.


Al Scott

MA (Hons) DipArch (Dist) 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.


Raphael Arthur

DipArch (Dist), BA (hons) - Architectural Assistant

Raphael has a keen interest in the broader social impact of architecture. He has worked on a number of projects with complex urban issues and with a focus on community engagement from a housing scheme for adults with autism, to a meanwhile use community development in South London. He enjoys testing form and pattern and has a particular specialism in graphic communication, playing an important role in the early stages of many IF_DO projects. Raphael graduated with Distinction from The London School of Architecture with a DipArch, having previously graduated from the University of Lincoln with a BA (Hons) in Architecture. Raphael has been part of the IF_DO team since 2015.

William Gottelier

BA (Hons) DipArch ARB - Architect

Will believes in community driven design and is particularly interested in the life cycle and legacy of architecture. Will has run a range of projects at IF_DO from intricate residential commissions to larger public projects including works to a scheduled monument in Suffolk. He takes care to consider the practical use and evolving future life of each design to ensure that buildings work hard for the people within them long into their occupation.

Will joined IF_DO in 2017 after graduating from the CASS School of Architecture with a DipArch, having previously gained a BA (Hons) from Kingston University. He has gained a wide range of experience having worked in a diverse variety of practices both in London and New York.

Geethica Gunarajah

MA BSc (Hons) ARB– Architect

Geethica is a highly skilled designer from inception through to technical detailing, and enjoys close collaboration with stakeholders and the wider design team through every project. She worked in both Berlin and Copenhagen during her training.

She has run a number of projects at IF_DO including the design of a new build house in Suffolk, and the exhibition design for the Klimt / Schiele exhibition at the Royal Academy (October 2018). Geethica joined the IF_DO team in 2017 having graduated from The Bartlett, University College of London with a BSc (Hons) in Architecture, and The Royal Danish Academy of Fine Arts, School of Architecture with a MA in Architecture.

Jack Banting

(BArch) - Architectural Assistant

Jack believes collaboration and sharing ideas are key to the architectural process. He enjoys helping clients to visualise projects and has brought a range of projects to life through model making, testing light, tectonics and scale. Jack has worked on a number successful competitions at IF_DO and has played a key role in recent new build housing.

Jack joined IF_DO in June 2017 following graduating from Nottingham Trent University with First Class Honours where he was nominated for the RIBA Bronze Medal.
