The concept of the street as the unit of the urban environment, and as a useful scale for the delivery of urban development towards sustainability, lies at the heart of this book. Bringing together individual experiences from different countries, it informs the debate not only as to what is desirable, but also how, practically, we should move forward. The chapters included will be of interest to many professionals and practitioners including architects, economists, engineers, environmentalists and planners. The contributors focus on architectural and spatial frameworks, the interests of the users, and issues of access and design.
