Stop separating the outside of your property from the inside of your house, try to think of your residence as all one place. Look at your outdoor space, look at your yard and take inventory of the you have naturally in the 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 own new outdoor living room such as a large tree, a hedgerow, a great 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 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.
