Stop separating the outside of your property 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 the things you have naturally in the 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 new outdoor living room such as a large tree, a hedgerow, a fantastic slope, or a beautiful view. In urban locations, your yard could be a barren rectangle, with nothing on it but some weeds and dirt, but there might be other qualities you could 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.
