It all starts with the base. In most situations people put their sheds on a level epice of their garden, in my case I have a sloping part of the garden where I want to put the shed. I didnt want the shed to start sinking again so this is what I did to create the base for the shed to sit on.
1. Dig 9 holes of similiar size 18 inches wide 18 inchines deep and 24 inches long.
The Foundation Holes
2. Fill them with about 10 inches of concreate.
Fill Holes with Concrete
3. Lay concrete blocks on each hole and because of the slop I hade to make sure that all the blockes wehe level with each other, I did this by putting in timber steaks into each hole and getting a straight edge and making sure it (the straight edge) was level, all you got to do it fill the hole with concrete up to a mark measure from the cross on the timber steak.
Level with Timber Steaks
Make sure Blocks are Level
4. Put down Plastic and cover with some sort of aggregete, in my case I had some gravel left over so that went down on the plastic, I only did this son to stop the weeds and to make the base under the shed clean and tidy.

and the finshed base then looked like the picture below
