This is a book that tells us clearly how far the elements of spatial quality of Urban Spaces are being influenced by Density and Patterns of Built-Forms. As Urban Design-Planner, I Suggest that Urban Design and Planning should start with proper computation of Density thresholds to determine patterns of Built-Forms so as to offer better quality urban spaces in the built-environments. So, this book has recommended Start planning and design with Appropriate application of Density , Density as prescription rather than Description .
