INTRODUCTION
Examples of spatial and volumetric compositions used in projects, shown in low-relief. The compositions illustrate the use of overlaid volumes and spaces.
The example compositions shown here are independent of the strategies for environment, structure and spatial arrangements described for each project.
The compositions are independent of scale; being used across the full range of design tasks, from masterplanning to facade design and internal volumes.
Themes explored in this book The projects in this book allow greater controlled daylight into interior
