New York's High Line park.
It's interesting to see a slightly different potential version of a raised sky-walk sort of area in New York. This kind of Utopia though is born of once again different motivations. It is repurposing old materials, as the residents of Bonnington Square in Vauxhall have done for instance, but it's also created by designers and developers. So it provides as interesting direct correlation between the two. Once again we're dealing with a development that is created as a subtle statement. A piece of architecture that quite literally raises the people on it above street level and constructs a dream world of flora for them to immerse themselves in.
