I can’t say enough about this book. When I first read A Pattern Language by Christopher Alexander it completely changed my outlook about what the built environment should strive for. The introductory book The Timeless Way of Building highlights the fact that humans are emotional creatures and that architecture should recognize this and be built to enhance the lives of the people that inhabit the places created. “A Pattern Language” takes that fuzzy concept of happiness, comfort and wholeness and details how to achieve it in the built environment with a scope that no book before or since has replicated. This books should be required reading for every architect, urban planner, engineer, and social activist.
