I love how this garden wall has incorporated natural boulders with the flagstone (maybe even manufactured stone?) and the poured concrete steps. It makes it look as if the house simply sprang up from the earth one day, fully formed, and has been here for ages. My Dream Home's yard will have something like this element - and as little lawn as possible.
Another fine example of what can be done with concrete. That is concrete shaped, stamped and colored to look like railroad ties. A great idea for those of you looking to fill dead space in a yard, without having to upkeep a flower bed. I'll show you guys how to build it in Yard Crashers 802.
