BN3 Architecture is a small, design-led practice based in Sussex — rooted in Brighton, but working far beyond its borders. Whether it’s a coastal renovation or a countryside new build, we create considered, contemporary homes that blend function with feeling. Founded by Bryn, a Brighton native with a love of elegant, timeless design, the practice is built on a deep appreciation for how we live and feel in the spaces we call home. With a background shaped by both travel and hands-on experience, Bryn brings a personal, practical touch to every project — understanding first-hand how to balance dream design with real-world budgets. Every project is a partnership. From the first call to the final sign-off, our process is collaborative, thoughtful, and clear.
