A new kind of practice informing the future of the built environment. Founded in 2012 by Tyen Masten, PHASE3 is a London-based practice that connects architecture, thinking and design to create big, serious, thoughtful projects. We have grown from where we started and are now a team of talented designers from diverse backgrounds and experiences. With mid to large scale projects in the UK and across Europe, the Middle East and the US, we have put our big ideas into a ground-breaking practice that takes a fresh and bold approach. We don't just create architecture – we design strategies. Strategies that enable us to distil the complex right down to its essence. Strategies that unlock hidden potential for our clients. Strategies that allow us to design at any scale. Strategies for Future Building: for our clients, for ourselves and for our cities.
