Stop separating the outside of your house from the inside of your house, try to think of your house as all one place. Look at your outdoor area, look at your yard and take inventory of what you have naturally in this space. What has mother nature already provided for you? Hopefully you might have some kind of natural elements that can be the focal point of your new outdoor living room such as a large tree, a hedgerow, a great 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 could possibly be other qualities you could 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.
