On the Babylonian architectural "hanging gardens" theme, a recent building in Sydney with significant external greenwall features,
One Central Park[0], was unceremoniously described to me by a nearby university community member as "where the prostitutes live". The unspoken implication being that nobody else could afford it, and people with family money went elsewhere. It's a shame because everyone agrees it looks better than other buildings. The cantilevered element was the source of some kind of council planning problem. In Sydney, such things are highly corrupt, as is our state government.
