A pattern based design method for landscape architects

This is the third part of a  podcast, based on Tom Turner's book on City as landscape. A design method is proposed which draws upon Christopher Alexander's Pattern language and other types of structuralist thinking. The method uses types of pattern: natural pattern structures, human pattern structures, archetypal pattern structures, and patterns found in the fine arts (painting, music, literature etc).  There is an illustrated version of this podcast on Youtube.
