Lawrence,

What I actually have is a 9x3 stone and mortar wall on top of a  
larger concrete footing. The wall forms part of the foundation. I  
could cantilever a slab out from it to gain a little more footprint  
if needed. Our plan is for a fire box and serpentine flu than is all  
on the same plane with a small oven and bench with a fieldstone  
veneer. I've seen such compact units but have no details.
