Megaprojects do not make real urban neighborhoods โ in one image:
"For American cities, the moral of the story is clear. On large brownfield and greenfield sites, cities should stop treating whole districts as single development packages to be handed to master developers. They should do the more civic work first of laying streets, subdividing land into buildable parcels, and issuing clear 'parcel passports' that specify what each site can become."
In what is BY FAR the best contemporary case of courtyard urbanism that I have seen, the Dutch are building fine-grained courtyard blocks (good ones!) on ARTIFICIAL ISLANDS off of Amsterdam.
But reclaiming land from the sea for courtyard blocks is not even the most interesting aspect of this. It's the development system, which uses a subdivision and parcel "passport" system to avoid megadevelopment and allow many builders and owners to participate in building out the courtyard blocks.
This is fascinating. You will want to read it. Link below.
