Stop separating the outside of your house 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 products 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 in it but some weeds and dirt, but there can be other qualities you might 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.
