 What are you planning to use for a foundation? Rubble trench?
		
 
 Yes.  Then the base of the house will be stacked boulders.
 
 I'm experimenting with the same idea as a rock jack.  Im working on an addition where I sunk the posts a foot or so and filled in with gravel.  Im stacking rocks around the posts to make wall bases, like in the house.
 
 Something like a rock jack covered in cob could make a nice house corner with a built in corner bench inside.
