My back yard slopes from front to back slightly. I was thinking I would level the ground as best I could, get a bunch of sand/crushed stone and lay that out, then make an 8'x8' square from 12" pavers. Is this not good enough, overkill, or just right? I live in New England so I don't (usually) have to worry about hurricanes. Manual labor is FAR from my specialty, so hopefully someone has some input.
