Well you tube doesn't leave any questions.
If you are raising your house yourself there are some precautions you should take. First, move deliberately and safely the witch was killed in the Wizard of Oz when the house fell on her and the same thing can mean your end; PROCEED WITH CAUTION.
I have raised a few small houses, like 12 to 24 inches. We used beams of wood under bearing walls and a 2 ton jack every 4' across the beams. Raise one beam at a time and no more than 1/4" at a time. Work in waves from one beam to another from front to back and start over again. Keep any beams cribbed up well while you are not working on them. One beam at a time,1/4" at a time and the house will eventually be raised to the position you want.
