It's a bit of a TreeHugger-y, preservationist mantra that the greenest building is the one that's already standing, making retrofits and renovations a better (and less wasteful) option over a complete demolition and building from scratch.
But what if a building is torn down? Well, before it is, it could at least perhaps serve another more artistic purpose, as British sculptor Alex Chinneck has done with this quirky installation called Open to the Public, which literally unzips the facade of an old 1960s building that's slated for demolition.
