This book takes the position that the dynamic of the architectural environment is a key aspect of good design, yet one which is not well anticipated or understood. Environmental variety is a design characteristic closely related to our experience of architecture - an architecture of the senses. Each chapter demonstrates how an understanding of a particular context or environmental characteristic in dynamic terms informs design. The book is an antidote to the misconceptions of 'optimum' environmental performance or fixed criteria, instead embracing the richness of environmental variety.
