Arboreal is an RIBA chartered architecture and design practice based in London and working on projects across the UK. We place deep sustainable thinking at the heart of what we do and our projects have been recognised for raising the bar of ecological design, helping our built environment tackle the crises of climate and ecological breakdown. We take a holistic approach to working with our clients, aiming to understand and respond to all the factors that influence a design project and to support its successful delivery from outset to completion. We work collaboratively across disciplines to bring together architecture, landscape, interiors, furniture and building services into cohesively resolved, beautiful places.


As director of Arboreal, Tom brings a diverse international background to the practice. His upbringing in the Findhorn Foundation intentional spiritual community in north-east Scotland set him on an early course towards sensitive attunement to the natural world. He was awarded scholarships to complete his studies at the Architectural Association before beginning his career working for Eric Owen Moss Architects in Los Angeles. Here he gained extensive experience with complex-geometry timber construction. After two further years working for Asymptote Architecture in New York, he returned to London to start Arboreal. Arboreal was co-founded in 2010 by Tom with his ex-classmate from the Architectural Association, Harry Paticas. In 2020 Harry left Arboreal to start a new practice - Retrofit Action for Tomorrow (RAFT) - with a focus on the sustainable retrofit of schools. Arboreal continues to pursue residential and community buildings both retrofit and new build.

Tom teaches environmental design at the Architectural Association and has previously taught design studios at the University of Westminster and Central Saint Martins, University of the Arts London. Arboreal is a member of the UK Architects Declare Climate and Biodiversity Emergency.
