Metropolitan urbanism proposes a model of design practice relevant to the landscapes of today’s urbanized regions. The approach activates three revisions to established design theory and practice: It challenges received ideas of city, suburb and periphery; it reconsiders established disciplinary boundaries between architects, landscape architects, urban designers, planners and civil engineers; and it recognizes the multiple roles of designers – as professionals with marketable expertise, cultural producers of meaningful form, and citizens defending an idea of public good.
