Hello!
We are potential buyers of a split-level house with a concrete foundation. To realize our ideas, we need to move the front door from one short side of the house to the other.
How is this done?
Do we break open the hole, cut with a stone saw, or what is the procedure?
If I've made the hole and find it's too big and not straight, what happens then?

Do you pour concrete around the door frame?
By the way, is it naive to think that one can renovate a bathroom for about 50,000 if you do a lot yourself, except for the moisture barrier..?
Best regards,
