Задний двор и палуба

I need a new deck, at a minimum, but I want to redesign the back yard, or improve the layout. Based on sunshine, shade, and privacy, I've placed the table on the existing flagstone. I think we should expand the flagstone and reshape the garden plots. I want to remove the red stone covering the ground and re-do it. I like having the two harden plots, in roughly the places they are right now. In the summer that is 3/4 sun. I want to have one main eating area and a place for lounging / relaxing. The screen porch is a nice place to hang out too, so the lounging should be near that door. The existing tree will stay in place. I would like other privacy along the back fence, in the form of trees or bushes.
