Backyard inspiration

I am presently working on designing my backyard space. Given that my house is a semi detached and has many levels, two of which need to be included in any backyard plan, it is posing quite the challenge. My neighbors all have big decks off their kitchens and nothing down below. I however, find that this offers no privacy and completely ruins the remaining green space on the main level. I have to come up with something more private and more interesting. 

Here are some of the photos that are inspiring me at the moment.
