RAPID URBAN PLANNING TOOLS FOR CITY EXTENSION
URBAN TYPOLOGIES
Tool number 3 showcases 12 basic urban typologies of residential and mixed
areas. Building types, plot sizes, public space and street-scape ranging from
low to high urban densities are being displayed.The selected 12 typologies
have been chosen to be easily distinguishable from one another but at
the same time frequently appearing in different parts of the world. Each
type is illustrated by orthophotos and street views of real world examples.
Demographic figures and indicators from urban planning give an assessment
of the typologies and allow for comparisons.Through the combination of a
quantitative assessment and qualitative descriptions and examples, the relation
of residential developments to their urban environment is being described and
evaluated.The tool helps to understand intertwined urban factors on an urban
neighborhood scale like FAR in relation to plot size or value of public space.
Selected examples from western countries as well as from the global south
ensure a diversified approach to the topic.
