This area was tricky to build, and I spent a lot of time figuring out where this unit should be placed. The ledge was a problem, I wanted it to be more to the west, but because of the ledge, and the new slope I would be creating by bringing in fill I was forced to locate the greenhouse where you see it. I'll bring something like 130 to 150 yards of fill. My little dump truck only holds about 3.5 yards so this is very time consuming.
