I think that if you take the majority of major urban centres, as we prograss out of the CBD, we see fantastic examples of urban sprawl. However, when we see urban renewal I think we see a sense of taking something chaotic and making it tidy - hence New Urbanism. If you go into any major city that has been modernaised we see major development in pedestrianisation, mixed development and a 'plan' style to everything. When developing a city, I tend to go for that approach - start at the centre and work my way out, because we know that all urbanised areas do this. We see villages swallowed into suburbia and green land eaten up in an array of concrete and asphalt, while at the same time my urban centre goes through a regeneration phase, things are simplified. Its a nice balance and it works for me, so as long as it works I shall continue to do it.
