By means of sketches and diagrams, it shows how they may be designed in to places or buildings. This is a practical book about architecture and urban design. It is most concerned with the areas of design which most frequently go wrong and impresses the idea that ideals alone are not enough. Ideals must be linked through appropriate design ideas to the fabric of the built environemnt itself. This book is a practical attempt to show how this can be done.
