I agree wholeheartedly on the subject of rainwater collecting and think it will look unsightly and spoil the over all look. I think that drainage should be incorporated and I will suggest it to the artist and the team. So, on that subject I'm afraid that at this point I can't give you a better answer.

Sorry gayle, but there we go again, something that any "architect/designer" worth his salt would have included as a matter of course.
