I just purchased a home in PA. The lot has a fairly steep incline. I would like to have a pool/spa installed but I am wondering if there are any special considerations.. Can I use the slope of the land itself to sort of stack the hot tub/pool/porch? I've seen pictures of this done but I have no clue how much more expense this would tack on. Would it be better to have the pool on a completely level area? There is a portion of the yard that has been cleared and leveled but it is on the side of the house and I was hoping to have the pool directly behind the house. Obviously, I will be hiring someone to come take a look and give an opinion, but I was curious if anyone has experience with this?
