I've seen this before. it can ether look good or really bad. Ive seen houses in the 100,000 dollar rage do there driveways like that or make them look like stone. it sticks out too much and looks really fake. I think you have to have a house that would normally have real stone or wood and then you can save money by making the faux style.
I LOVE IT!! I imagine putting a nice rug and furniture on it!
