Ecology is the study of the relationship between organisms and their environment. Through their teaching at the Architectural Association, the editors have shown how this definition also suits the discipline of architecture surprisingly well. Correlating morphogenesis and ecology, they have developed a new framework for architectural design that is firmly rooted within a biological paradigm, and thus concerned with issues of higher-level functionality and performance capacity. They have named this approach Morpho-Ecology. The first part of the book introduces the theoretical and methodological framework for their approach; the second part presents 20 research projects undertaken by students; and the third part contains the proceedings of the 'Differentiated systems in Nature and Design Symposium' held at the AA.
