That kind of construction doesn't exist in eastern NC. Probably not in any of NC except maybe the mountains. It is interesting though, however in the end I wonder how much cheaper it is than a regular concrete footing and masonry wall.
Well I actually have the original invoice. Now keep in mind this was 1994. But the entire foundation cost $11,692.00. Thats for roughly a 50' x 30' foundation. I have no idea if that was expensive or cheap for that day.
If I were to build my own house I would do poured walls.
