First edition, first printing of A New Theory of Urban Design, published by Oxford University Press in 1987 as Volume 6 of the Center for Environmental Structure series. The copyright page shows a complete number line ending in 1, confirming the first printing. Christopher Alexander and his coauthors present a theory of urban design based on creating cities as organic, coherent wholes rather than as collections of isolated buildings and planning decisions. The book develops seven practical rules for urban growth and tests them through a large-scale simulated redesign of a high-density area of San Francisco, illustrated with photographs, plans, diagrams, and architectural studies. The original hardcover retains its dust jacket and the original $39.95 flap price. ISBN 0-19-503753-7. Your copy appears very clean overall, with only light wear and some age toning to the jacket. Bibliographic sources confirm the 1987 Oxford University Press edition at 251 pages.
