“I haven’t done this yet (yes, I knew about it before) because I live in a multi unit apartment building. As progressive as I would like to imagine my town is, I cant see the zoning permit people, let alone the apartment owners, jumping all over the idea.
Once I have my own place (hopefully a fun little brownstone in the city) I will be immediately looking into the specifics of green roofing with a percentage of space devoted to a garden.
Also, contrary to popular belief, you can fairly easily install a green roof on a pre-existing slanted roof.”
