Krier wants these witty images to be tools for re-founding traditional urbanism and architecture. He argues for mixed-use cities, of "architectural speech" rather than "architectural stutter," and pointedly plots the man-vehicle-landneed ratio of "sub-urban man" versus that of a city dweller. In an age of energy crisis, he writes (and his drawings show), we "build in the wrong places, in the wrong patterns, materials, densities, and heights, and for the wrong number of dwellers"; a return to traditional architectures and building and settlement techniques can be the means of ecological reconstruction. Each of Krier's provocative and entertaining images is worth more than a thousand words of theoretical abstraction.
