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