This is where the cabin takes a very interesting turn. The foundation consists of two parts - 36" Sonotube pads poured 12" thick, reinforced with re-bar on a gravel bed surface. That was pretty normal. The 10' tall metal frame fabricated from reclaimed heavy duty guard rail and knee braces from an old Quonset were totally new, unexpected, burly and, well, beautiful.
Because the dozer had not shown up by the time the pallet of concrete bags arrived - Pat and Dustin got to digging holes for the footings and moving the 50+ 80lb. bags of concrete across the stump riddled access.
