Resumen de Typologies and Basic Descriptors of New Zealand Residential Urban Forms

Sumita Ghosh, Robert Vale

• This paper presents an urban taxonomy or classification system for New Zealand settlement forms across five urban scales: metropolitan/regional, sub-metropolitan/city; community/neighbourhood; local/residential block and houses/micro. It provides taxonomical descriptions and density patterns of existing and emerging New Zealand residential urban forms at neighbourhood and local levels. Considering seven case studies in the Auckland Region, this paper formulates a set of basic quantitative urban form descriptors within the urban taxonomical framework. An analysis of these descriptors indicates that dwelling and household densities and spatial distributions of built-up roof areas, vegetation, productive land, impervious pavements and pathways reflect their urban form characteristics. These varying qualities can be linked to the appraisal of environmental sustainability performances of different urban forms.
