Planners and designers should encourage as much diversity in human habitats as they find in animal habitats. It is not possible to resolve all conflicts or to gain all ends. Choices have to be made. Different aspects of the public good should be stressed in different places. To achieve variety in land use patterns, there should also be a variety of relationships between the professions, not an institutionalized decision-making tree. Relationships between the constructive professions should, therefore, be deconstructed.
