Stop separating the outside in your home 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 you have naturally in that space. What has mother nature already provided for you? Hopefully you will have some kind of natural elements that can be the focal point of the new outdoor living room area such as a large tree, a hedgerow, an excellent slope, or a beautiful view. In urban locations, your yard could be a barren rectangle, with nothing inside it but some weeds and dirt, but there could possibly be other qualities you may 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.
