Stop separating the outside of your property from the inside of your house, try to think of your property as all one place. Look at your outdoor space, look at your yard and take inventory of the things you have naturally because space. What has mother nature already provided for you? Hopefully you possess some kind of natural elements that can be the focal point of your new outdoor family room such as a large tree, a hedgerow, a nice slope, or a beautiful view. There can be other qualities you could potentially start with, such as a lovely angle of morning sun, maybe a nice brick wall in one side creating a microclimate, or even an interesting urban view of some kind, though in urban locations, your yard can be quite a barren rectangle, with nothing in it however, some dirt and weeds.
