Stop separating the outside of your house from the inside of your house, try to think of your premises as all one place. Look at your outdoor area, 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 have some kind of natural elements that can be the focal point within your new outdoor living room 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 it but some weeds and dirt, but there might be other qualities you can 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.
