Stop separating the outside in your home 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 that 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 the new outdoor living area such as a large tree, a hedgerow, a good slope, or a beautiful view. There could possibly 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, though in urban locations, your yard may be a barren rectangle, with nothing in it however, many dirt and weeds.
