Any chance of your placing the virtual camera at the center of the back yard lawn area and aiming square on at each lot line and toward the patio area and posting those pics? I would like to see things a little closer up. How nice it is that someone shows up here with a PLAN for a change!!!

Hopefully these will help Yardvaark, I have been planning this in my mind for years just waiting for the perfect dilapidated property to come on the market for the project :)

These views are still too distant and from strong angles, making it more difficult to understand details of how things fit together. You can't do square views on from the back yard center? If no, please say.

In the meanwhile one thing seems to jump out as somewhat out of kilter: usually, pool areas are very attractive so fit well at the foreground and conjoin harmoniously with patio space (pool + deck), and usually, playgrounds are considered a touch less attractive & moved toward the background. Here, they are reversed which does not seem ideal. Maybe you could justify why they are this way ...?

If the garden area is attractive, I don't see why the low wall divides the patio from it. I think the primary problem is possibly the overall organization and where things are located. The patio does not need to be a straight line across the lot. I think a more interesting integration into the yard would be a plus. Also, the patio seems to have no shade from trees, and not much in the way of plantings that are close to it. Seems a negative to me. I wonder how you got to this scheme and what your thinking was along the way of why the different areas are where they are.

One other thing to mention is if you've checked the legal requirements insofar as building setbacks from the lot line are concerned. Wouldn't want to plan a pool house next to the line to discover it wouldn't fly with the authorities and neighbors.
