Would it be cheaper to put a foundation in? They never seem to do that here with buildings...They have like 2 Haitians dig their 6 foot pits, put a giant toothpic in the center cover it with mesh, than hug it with a thin coat of goat milk cement..When they set the floors, its all a balancing act..I'm shocked that when finished, every tenant does not get instructions on how to place their belongings..Nope, Nope, too much weight over here. the building just moved, sofa there please..But serious, for a smal area, do they not sell sheds here?? pour a foundation, anchor shed. very solid..Or would you not at least save some cost on the blocks? Sorry, I have no idea about the cost of materials here...If they had a home depot, I could say better.
