Stop separating the outside in your home 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 the items 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 of your 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 within it but some dirt and weeds, but there may be other qualities you could potentially 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.
