Well the answer would be no, hence why I don't live in a city and I live in the Chiltern AONB.
However, I don't see how these landscaped areas are that beneficial? There's so many houses in one area, with the layout being optimised for # of properties, that you're surrounded by other houses more than greenery.
I don't see housing estates that are saying 30 years old with landscaped open spaces or children's parks in the middle of them. Perhaps councils are forcing these new estates to have mini parks in them as local ones become saturated as population grows.
There is so much contradiction in the above post its hard to know where to start.
You dont want to live in a concrete jungle. I think it would be fair to say that most people would want the same. Yet, in the next sentence you fail to see what benefits that open, landscaped areas within modern developments will have. So which is it? Have them as concrete jungles with no open areas, which people don't want, or have some open areas for people to relax in?
As for housing estates from 30 years ago not having open spaces/children's parks etc - Would it be fair to say that developers have learned that the concrete jungle estates you describe are not ideal hence why they changed to having open spaces within them?

Is it possible that, given you live in an AONB, you may have a bit of a blind spot in this discussion?
