1 City Layers

Evolution & Change

2 Challenge 3 Community & Vitality

4 Future


Places of exchange, commerce & vitality


Diverse layers of heritage, community & functions


Variety, Opportunity & Complexity


Delightful & Sustaining


Integrated climate response and function


Interconnected functional layers forming a complex mechanism


Evolution - and more radical changes Development Population Growth Complexity


Participation


What happens when it goes wrong?

Urban Monoculture in places that are still required to perform multiple functions


Fragmentation & sharp, broken edges


Challenge of a city-scape of different parts not integrated layers


Complexity = positive Complication = negative


Some environments delivered as individual parts


Sometimes the important layers get a bit lost


Complexity = positive Complication = negative


Layering & integration of different active transport modes


Distribution of space responsive to demand


environmental quality


Retrospective adjustment


Residential street = Residential character


Recipe for success - Tendency to repeat the familiar formula?


Is too much of the future character sometimes


Seeking value within urban design - a complex multi-layered assessment


Unlock the potential of local community passions & innovation - the vibrant community dimension behind the plans


In the current climate, should the design & planning process be more opportunistic, and support a slightly more messy process?


Experimental or short-term opportunities?
