Points + Lines: Diagrams and Projects for the City is a book of New York architect Stan Allen's writings and projects that propose new architectural strategies for the contemporary city. Organized in the form of a user's manual, it juxtaposes speculative texts outlining Allen's general principles with specific projects created by his office. The book's title refers to this interplay of practice and theory, evoking not only the points of activity and the paths of movement found in a contemporary city but also the points of speculation and lines of argument in theoretical discourse. Projects include the Cardiff Bay Opera House, Wales; the Korean-American Museum of Art, Los Angeles; the Museo del Prado, Madrid; and White Columns Gallery, New York. Each project is accompanied by explanatory text as well as numerous drawings, models, photographs, and computer renderings. K. Michael Hays contributes an introductory essay; R. E. Somol writes the postscript.
