When I got married and we had our first (and only) house one of the first things I did was get rid of all lawn. As a teenager I had to mow the lawn with a crappy electric lawnmower with a long extension cable for power. Australia is not an ideal place for lawn. Lawn is one of the most labour intensive gardens you can have. So I got rid of it all and planted trees, shrubs, ground coverers, laid small areas of paving, and now that we have rebuilt the back half of the house we have a lovely large deck. No lawn anywhere.
Mind you our block is only 10 metres wide so it's easy to fill with trees. Our back yard is not much bigger than 10m x 10m and we have six trees in it. My dream is to live in a forest, so this is as close as I'll get.
