Mike Tonkin Director
PhD, MA, RCA, ARB, RIBA, FRSA
Mike Tonkin established his practice after leaving the RCA in 1989 and founded Tonkin Liu with Anna Liu in 2002. Mike’s professional practice has been consistently informed by a distinctive pursuit of formal lessons observed from the natural world. The work has also been informed by an understanding of vernacular architecture observed during extensive travels around the world. Over the last twenty years Mike has taught and lectured at numerous schools of architecture, including the AA, the Bartlett School of Architecture (University College London), the University of Cambridge, Bath, the RCA and the University of Westminster. He lectures on a number of subjects including global vernacular architecture, and nature-focused, place-specific, storytelling methodology for architectural innovation.
