In Deep Design, David Wann explores a new way of thinking about design, one that asks "What is our ultimate goal?" before the first step has even been taken. Designs that begin with such a question -- whether in products, buildings, technologies, or communities -- are sensitive to living systems, and can potentially accomplish their mission without the seemingly unavoidable side effects of pollution, erosion, congestion, and stress. Such "deep designs" meet the key criteria of renewability, recyclability, and nontoxicity. Often based on natural systems, they are easy to understand and implement, and provide more elegant approaches to getting the services and functions we need. Wann presents information gleaned from interviews with more than fifty innovative designers in a wide variety of fields, and describes numerous case studies that explain the concept and practice of deep design.
