Thanks for the reply. So what your saying is the actual size of the block foundation for a Pompeii 42' that sits on top of the 77' x 86' slab is considerably smaller than the size of the slab. And that the slab is oversized to accomodate the style of enlosure such as a house style that will take up some of that slab? Is that correct?

Do you know off hand what the minimum size slab I could get away with for building a Pompeii 42' would be? I know I have room for a good size slab, just not sure if I have enough room for a 77' x 86' slab. Thanks, Franco
