The second of three books published by the Center for Environmental Structure to provide a "working alternative to our present ideas about architecture, building, and planning," A Pattern Language offers a practical language for building and planning based on natural considerations. The reader is given an overview of some 250 patterns that are the units of this language, each consisting of a design problem, discussion, illustration, and solution. By understanding recurrent design problems in our environment, readers can identify extant patterns in their own design projects and use these patterns to create a language of their own. Extraordinarily thorough, coherent, and accessible, this book has become a bible for homebuilders, contractors, and developers who care about creating healthy, high-level design. A great read and a critically-acclaimed book for those who are interested in urban planning. Condition: 8/10. The paper sleeve of the book has some dark streaks on its cover, as well as some creases on its vertices. Otherwise, I haven't read the book and it has been stored in a ziplock bag away from other books to prevent yellowing since its purchase. The inner pages are still very clean and pretty much in pristine condition. Selling as I purchased this book on an impulse, and I can neither find the time to read it nor the space to store it. Originally purchased from Amazon US at approximately 50 SGD (i.e. 38.4 USD) as of listing date's exchange rate. This compares favourably with the book's current selling price of 43.16 USD at Amazon US.
