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 space, look at your yard and take inventory of what you have naturally because space. What has mother nature already provided for you? Hopefully you have some kind of natural elements that can be the focal point of the 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 inside 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.
