Seen it done many times. The house was jacked up from the old foundation on heavy steel beams, and cribbed up. A ramp was dug into the dirt on a side, and the old foundation and surrounding dirt was removed with a skid loader. New foundation and walls poured, house sat down on the new walls, cribbing and beams removed. New floor poured and windows installed in the walls where the beams were. Backfilled and done. That's the simplified version, but it pretty much covers it.
Of course the new plumbing, heating, and electrical went in like normal.
This is the right way to do it. Put in 9 foot walls and you'll have a very nice space when finished. Could even put floor heat in the new basement slab. Putting in new footings allows you to install drain tile so that the new basement will stay dry in the future. I guess all of this depends on if the upstairs part of the house is good enough to invest in a new basement. |
