An Architecture Notebook builds on the foundation of Simon Unwin's previous book Analysing Architecture (Routledge, 1997). Using numerous examples, illustrated with clear line drawings, this volume describes and illustrates the many powers attaching to one of the most basic of architectural elements, the wall.Like its predecessor, An Architecture Notebook is a stimulus to thinking about what one can do with architecture. It also offers an example to student architects of how they might keep their own architecture notebooks, collecting ideas, sorting strategies, generally expanding their understanding of the potential of architecture in changing the world.
