fixing my greenhouse

Hi LD

not sure if you like this idea or not this is what i done for my greenhouse base.
i got some old door linings made up a frame for the base, i drove stakes in the ground so they went in about a foot and a half and about two foot on the corners i then cut them off all level so there was about four inchs left out of the ground then placed the frame on it, i then used pallets to fill the gap.  i then filled in the space with some spare soil to raise the floor a little the added a layer of cardboard then some weed fabric and then sharp sand to lay the slabs on. and cut the slabs to fit inside.
