Rannveig - Empty canvases are the best! That way, you can envision what you want and then watch it take off! When I bought my house in '05, I bought it for 2 reasons: the neighborhood (older, single family homes, no HOA, kids playing street-hockey in the cul-de-sac type place) and the huge dead yard in the back. I knew that the yard was going to be a MAJOR piece of work, and it has... it has! But, it is slowly getting to what I envisioned years ago, just takes time.
Make sure you take pictures of the yard BEFORE you start working it - kind of show your progress. I regret not taking that many pictures of my yard before.
