Living Architecture was written in the wake of the recent devastating Japanese tsunami and reflects on some of the architectural practices that underpin modern urban development. It asks the question 'why do we, as living creatures inhabit things that are not alive?' and sets the scene for fundamentally different ways of making structures and materials. New possibilities are discussed in the context of recent scientific developments. `Living technology' is a set of new technologies whose performance lies somewhere between machines and biology. As such, they blur the distinction between living and non-living processes as well as challenge the separation assumed to exist between a building and its natural environment. Living Architecture proposes a new relationship for urban development where people work in concert with and orchestrate the forces of nature using living technology to create new architectural outcomes. The proposed approaches are compatible with ecologically engaged practices such as, Panarchy, Permaculture and Biomimicry and takes a multi-systems view of Living Architecture at many scales of operation ranging from the micro scale, to the city. Living Architecture is at an early stage of development but its speculative approach is based on real world experiments, which are also discussed in this book. Additionally Living Architecture reflects on a possible alternative scenario for the devastated Sendai coastal region should the potential of living architecture be fulfilled, which takes the form of a short science fiction story.
