Book excerpt: 'Urban Design: Ornament and Decoration' focuses on decorating the city and how ornament has been used to bring delight to the urban scene. The authors show how the pattern and distribution of street and square and other major elements in the city can be enhanced by the judicious use of decorative surface treatment and by the careful placing of hard and soft landscape features. This second edition, updated by Cliff Moughtin and now available in paperback, includes a new chapter on mud architecture. Case studies of city decoration are also outlined to bring together the ideas discussed and to show how ornament and decoration can be used to emphasize the five components of city form: the path, the node, the edge, the landmark and the district.
