Hi, my home had a one car carport that was enclosed and finished as a garage. Now that we are the homeowners we would like to raise the floor up to the rest of the house and finish it as another heated room. How do I begin to raise the concrete floor up to a wood floor? My main concern is that the concrete floor is now sloping from front to back. So I am unsure how to level the floor and raise it. I'm fairly new to home ownership but would like to do some of the work myself. Please advise.
