It's interesting to see failed developments that have never gone anywhere. My first instinct is to say : start re-using these instead of building new ones. But then the reason they failed is because nobody wanted to live there, for whatever reason. Those reasons are probably still there, so any attempt to make them 'work' is doomed to failure. Best to just let it be. Eventually the two or three occupants will move on and then nature can reclaim the land.
