Allford Hall Monaghan Morris (AHMM) was established in 1989 by Simon Allford, Jonathan Hall, Paul Monaghan and Peter Morris. The four founding directors had met at The Bartlett School of Architecture and worked together on their final year diploma project, The Fifth Man. This project would prove to be significant in establishing a way of working that has endured throughout AHMM’s thirty years in practice. From its beginnings as four founders, the practice has grown to more than 400 employees based in London, Bristol and Oklahoma City. AHMM makes buildings that are satisfying and enjoyable to use, beautiful to look at and easy to understand. The practice designs very different buildings for very different people to use in very different ways, making places as well as buildings that work over time and have lasting qualities intrinsic to their architecture. Winner of the RIBA Stirling Prize.
