If the backyard is small or back onto a road, there is no point to go for a walkout. A walkout basement should come w/ a large backyard which opens into a great view, for example, a lake at the back. This is what a walkout should be built for. Developers nowadays are selling small walkout lots to those who blindly run after the word "Walkout basement" Better not to choose one that you would find yourself walking out and right against a fence.
