Stop separating the outside of your property from the inside of your house, try to think of your premises as all one place. Look at your outdoor space, look at your yard and take inventory of the items you have naturally in the space. What has mother nature already provided for you? Hopefully you might have some kind of natural elements that can be the focal point of your respective new outdoor living room area such as a large tree, a hedgerow, a good slope, or a beautiful view. There may 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 be a barren rectangle, with nothing in it but a majority of weeds and dirt.
