In book two of this four-volume work, Alexander explains in detail the kinds of process that are capable of generating living structure. The unfolding of living structure in natural systems is compared to the unfolding of buildings and town plans in traditional society, and then contrasted with present-day building processes. The comparison reveals deep and shocking problems which pervade the present day planning and construction of buildings. Pervasive changes are needed to create a world in which living process - and hence living structure - are possible; these are changes which are ultimately attainable only through a transformation of society. It is the use of sequences which makes it possible for each building to become unique, exactly fitted to its context, and harmonious. And it is also this use of sequences which makes it possible for people to participate effectively in the layout of their own buildings and communities

In Book 3 of this four-volume work, Alexander presents hundreds of his own buildings and those of other contemporaries who have used methods consistent with the theory of living process.

Nearly seven hundred pages of projects, built and planned in many countries over a thirty-year period, illustrate the impact of living process on the world. The book provides the reader with an intuitive feel for the kind of world, its style and geometry, which is needed to generate living structure in the world and its communities, together with its ecological and natural character.

The projects include public buildings, neighborhoods, housing built by people for themselves, public urban space, rooms, gardens, ornament, colors, details of construction and construction innovation. The many buildings shown, and the methods needed to design and build these buildings, define living structure in a practical way that can be understood and copied.

." . . Alexander's approach presents a fundamental challenge to us and our style-obsessed age. It suggests that a beautiful form can come about only through a process that is meaningful to people. It also implies that certain types of processes, regardless of when they occur or who does them, can lead to certain types of forms."-Thomas Fisher, former editor of "Progressive Architecture."

Christopher Alexander is a fellow of the American Academy of Arts and Sciences, architect, builder, and author of many books and technical papers. He is the winner of the first medal for research ever awarded by the American Institute of Architects, and Emeritus Professor of Architecture at the University of California, Berkeley, where he taught for 40 years.

"These notes are about the process of design: the process of inventing things which display new physical order, organization, form, in response to function." This book, opening with these words, presents an entirely new theory of the process of design.

In the first part of the book, Mr. Alexander discusses the process by which a form is adapted to the context of human needs and demands that has called it into being. He shows that such an adaptive process will be successful only if it proceeds piecemeal instead of all at once. It is for this reason that forms from traditional unselfconscious cultures, molded not by designers but by the slow pattern of changes within tradition, are so beautifully organized and adapted. When the designer, in our own self-conscious culture, is called on to create a form that is adapted to its context he is unsuccessful, because the preconceived categories out of which he builds his picture of the problem do not correspond to the inherent components of the problem, and therefore lead only to the arbitrariness, willfulness, and lack of understanding which plague the design of modern buildings and modern cities.

In the second part, Mr. Alexander presents a method by which the designer may bring his full creative imagination into play, and yet avoid the traps of irrelevant preconception. He shows that, whenever a problem is stated, it is possible to ignore existing concepts and to create new concepts, out of the structure of the problem itself, which do correspond correctly to what he calls the subsystems of the adaptive process. By treating each of these subsystems as a separate subproblem, the designer can translate the new concepts into form. Theform, because of the process, will be well-adapted to its context, non-arbitrary, and correct.

The mathematics underlying this method, based mainly on set theory, is fully developed in a long appendix. Another appendix demonstrates the application of the method to the design of an Indian village.

The first edition of Tunisia was released just nine months before the eruption of the Arab Spring. The most substantial period of political unrest felt by the Arab world in a half century originated in Tunisia, a fact that confounded expectations about Tunisian politics. This new edition builds upon the first edition's overview of Tunisia's political and economic development to examine how one of the region's hardiest authoritarian orders was toppled by a loosely organised protest wave. Providing the most up-to-date introduction to Tunisia's post-independence and post-Arab Spring politics, concisely written chapters cover topics such as: state formation domestic politics economic development foreign relations colonialism the Arab Spring; its factors and repercussions Key to this new edition is the examination of Tunisian history, politics and society alongside the subsequent upheaval following the outbreak of revolts in December 2010. It looks at how political and economic changes after 2001, including economic deterioration and rising inequality and corruption, had already begun to erode bases of Ben Ali's government, and explores why Tunisia is the sole Arab Spring country to construct a democracy thus far, and the challenges that this new democracy still faces. An essential inclusion on courses on Middle Eastern politics, African politics, and political science in general, this accessible introduction to Tunisia will also be of interest to anyone wishing to learn more about this significant region.

In this radical new look at the theory and practice of urban design, Christopher Alexander asks why our modern cities so often lack a sense of natural growth, and suggests a set of rules and guidelines by which we can inject that `organic' character back into our High Streets, buildings, and squares. At a time when so many of Britain's inner cities are undergoing, or are in need of, drastic renovation, Christopher Alexander's detailed account of his own experiments in urban-renewal in San Francisco makes thought-provoking reading.

As an innovative thinker about building and planning, Christopher Alexander has attracted a devoted following. His seminal books--The Timeless Way of Building, A Pattern Language, and The Oregon Experiment--defined a radical and fundamently new process of environmental design. Alexander now gives us the latest book in his series--a book that puts his theories to the test and shows what sort of production system can create the kind of environment he has envisioned.
The Production of Houses centers around a group of buildings which Alexander and his associates built in 1976 in northern Mexico. Each house is different and the book explains how each family helped to lay out and construct its own home according to the family's own needs and in the framework of the pattern language. Numerous diagrams and tables as well as a variety of anecdotes make the day-today process clear.
The Mexican project, however, is only the starting point for a comprehensive theory of housing production. The Production of Houses describes seven principles which apply to any system of production in any part of the world for housing of any cost in any climate or culture or at any density.
In the last part of the book, "The Shift of Paradigm," Alexander describes, in detail, the devastating nature of the revolution in world view which is contained in his proposal for housing construction, and its overall implications for deep-seated cultural change.

You can use this book to design a house for yourself with your family; you can use it to work with your neighbors to improve your town and neighborhood; you can use it to design an office, or a workshop, or a public building. And you can use it to guide you in the actual process of construction.
After a ten-year silence, Christopher Alexander and his colleagues at the Center for Environmental Structure are now publishing a major statement in the form of three books which will, in their words, "lay the basis for an entirely new approach to architecture, building and planning, which will we hope replace existing ideas and practices entirely." The three books are The Timeless Way of Building, The Oregon Experiment, and this book, A Pattern Language.
At the core of these books is the idea that people should design for themselves their own houses, streets, and communities. This idea may be radical (it implies a radical transformation of the architectural profession) but it comes simply from the observation that most of the wonderful places of the world were not made by architects but by the people.
At the core of the books, too, is the point that in designing their environments people always rely on certain "languages," which, like the languages we speak, allow them to articulate and communicate an infinite variety of designs within a forma system which gives them coherence. This book provides a language of this kind. It will enable a person to make a design for almost any kind of building, or any part of the built environment.
"Patterns," the units of this language, are answers to design problems (How high should a window sill be? How many stories should a building have? How much space in a neighborhood should be devoted to grass and trees?). More than 250 of the patterns in this pattern language are given: each consists of a problem statement, a discussion of the problem with an illustration, and a solution. As the authors say in their introduction, many of the patterns are archetypal, so deeply rooted in the nature of things that it seemly likely that they will be a part of human nature, and human action, as much in five hundred years as they are today.
