Spacematrix : space density and urban form Spacematrix explores the potential of urban density as a tool for urban planning and design. The authors fascination with density is driven by the desire to understand the relational logic between density urban form and performance. This is a prerequisite for understanding and successfully predicting the effects of specific designs and planning proposals. The focus of attention is the relationship between types of urban environment and data such as amount size and physical properties.0Berghauser Pont and Haupt demystify the use of image based references and concepts such as urbanity compact city and park city by challenging the reliability of such concepts and critically examining the possibility of redefining them through the concept of density.00Spacematrix is of interest to architects as well as urban planners and designers but is equally relevant for other professionals working in the field of urbanism such as developers economists engineers and policymakers
