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 space, 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 might have some kind of natural elements that can be the focal point of your own new outdoor living room such as a large tree, a hedgerow, an excellent slope, or a beautiful view. 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, though in urban locations, your yard may well be a barren rectangle, with nothing in it but a majority of dirt and weeds.
