Roger Neville Walker (born 1942, Hamilton, NZ) is a New Zealand architect based in Wellington. After graduating in architecture from the University of Auckland in the 1960s, Walker worked for the architecture firm Calder Fowler & Styles, until he established his own practice in the early 1970s. He now runs Walker Architecture & Design in Wellington.Like his compatriot Ian Athfield, Walker is notable for his unconventional design approach, which came out of a reaction against the then-dominant modernist architecture in the 1960s and 1970s.
