Stop separating the outside of your house from the inside of your house, try to think of your property as all one place. Look at your outdoor area, look at your yard and take inventory of the things you have naturally for the reason that space. What has mother nature already provided for you? Hopefully you may have some kind of natural elements that can be the focal point of your new outdoor family area such as a large tree, a hedgerow, a nice slope, or a beautiful view. There might 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 could be a barren rectangle, with nothing in it but a majority of dirt and weeds.
