Stop separating the outside of your property 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 items you have naturally for the reason 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, a nice slope, or a beautiful view. In urban locations, your yard could be a barren rectangle, with nothing inside but some weeds and dirt, but there might be other qualities you may start with, such as a lovely angle of morning sun, maybe a nice brick wall using one side creating a microclimate, or even an interesting urban view of some kind.
