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 area, look at your yard and take inventory of the items you have naturally in this space. What has mother nature already provided for you? Hopefully you have some kind of natural elements that can be the focal point of your own new outdoor family 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 can be other qualities you could start with, such as a lovely angle of morning sun, maybe a nice brick wall on a single side creating a microclimate, or even an interesting urban view of some kind.
