Challenging existing assumptions about how our towns and cities are structured and formed, Julian Hart provides an engaging and thought-provoking alternative theory of urban design. This is not urban design in the sense of the practice of design; rather it is a theory of the form of the town at all scales - why towns and cities happen to be structured the way they are as a result of the social, political, legal and (especially) economic forces that create them. The shape of the city at every scale, from the internal configuration of dwellings all the way up to the superstructure of the whole.
