Stop separating the outside of your dwelling from the inside of your house, try to think of your home as all one place. Look at your outdoor area, look at your yard and take inventory of the things you have naturally in this space. What has mother nature already provided for you? Hopefully you possess some kind of natural elements that can be the focal point of your respective new outdoor living room such as a large tree, a hedgerow, a nice slope, or a beautiful view. There might be other qualities you can 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, though in urban locations, your yard may be a barren rectangle, with nothing in it however, some dirt and weeds.
