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