We have a messy backyard. There is basically no layer at all, but has almost all sorts of things...big trees, small trees, play unit, concretes...We wanna change as little things as possible to do a makeover. My hubby has dig the lawn out and wanna to put the new one on the dirt area next to the concrete. We are thinking to enlarge the concrete area a bit (maybe)? Any idea would be appreciated. Thanks so much.
