Google Earth + SketchUp is a great combination. You can open the view of your site in Google Earth, then open SketchUp, and with one click get the view of your site from Google Earth into SketchUp so you can draw right on it. It can even automatically calculate shadows, so you can see what parts of your garden are shaded by buildings and for how much of the day. And it's free.
Wow I feel like I'm a kid again with Sim City. Sketch up is a blast, thanks for telling me about it. Its going to take me a week or so to get comfortable with it, but I can see it is going to be very useful.
