Stop separating the outside of your dwelling from the inside of your house, try to think of your house as all one place. Look at your outdoor space, look at your yard and take inventory of the things you have naturally in the 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 your respective new outdoor living room area 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 dirt and weeds, but there may be other qualities you might 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.
