My property is similar, sloping away from the house to maybe 40’ below in all directions. I wonder how much of an issue that is with a 4 square. The property is about 300 x 300 square so there is no real room for any beverages. The 4 square would be sitting maybe 25’ below the high point (SE corner) of the property with mostly equal to lower elevation in the surrounding terrain.
