  • clean down to bare, hard ground;
  • cover ground with a few inches of crush gravel, level and compact it;
  • build your frame on top of this gravel;
  • butt connect 2 4X4s by sistering a 4' length of 2x4 inside along the butt joint and secure with 2 or 3 carriage bolts on each side of the butt join. This joint needs to be strong;
  • fill the outside perimeter of the foundation frame with gravel, so that rodents cannot live under it. (skunks do this a lot where I am). I would fill the whole foundation to the top of the 2x4s to not risk it. Actually, I would just pour a concrete foundation.
  • all lumber on the ground should be pressure treated and any cut boards should have the ends treated.
  • if the area is prone holding water on top, consider raising the area with dirt so in the end, your foundation never sits in water. Pressure treated lumber ain't what it used to be.
  • Good Luck!
