HARRY CASSELL
Harry is an award-winning architect and entrepreneur with a passion for creating thoughtful, sustainable spaces that support healthier, more connected communities. He has led a wide range of projects across the UK and internationally, always placing social responsibility and environmental impact at the heart of his work.
Before founding Cassell Architects in 2023, Harry co-founded the award-winning practice Cassell Tarring, where he helped shape a portfolio of refined, contemporary residential projects known for their clarity, craft, and contextual sensitivity.
Cassell Architects was established with a clear mission: to design architecture that strengthens people’s relationship with the built environment—whether through homes, community spaces, or public buildings. That commitment has already been recognised, with the Wormley Community Centre receiving a High Commendation at the AJ Retrofit Awards 2024.
Harry brings together strong design sensibility, meticulous attention to detail, and a deep understanding of the construction process—ensuring high-quality outcomes at every stage of a project.
AWARDS
Cassell Architects is proud to have received multiple accolades, including a High Commendation from the Architects’ Journal for our Wormley Community Centre project at the AJ Retrofit Awards 2024 — a testament to our commitment to thoughtful, transformative design.
