How can a floor be raised to the level of the adjacent rooms?

My living room floor in my 1970's home is "sunken" -- about 6 inches lower than the floors in the adjacent rooms. What is the best way to raise the floor to the level of the other rooms?

    My son had the same problem- he built a wood frame the proper height and put a wood floor in-Matched the floor adjacent to the new one- looks very nice. He thought of adding concrete- but would have been too expensive-he used wood flooring from Costco.

    As long as the ceiling in the living room is the same height as the rest of the house, you could frame it up with 2x4s then put plywood over it, then the flooring that you want. If there's carpet in the living room, that will have to be removed. Keep in mind that any window will be lower and if there's a door, it will have to be taken out and raised.

  • We just went through that! Only our sunken living room was down about 16" and actually impeded on the basement room below it. The contractor had to totally remove the floor joists and reset them on built up rims. Here is a post with a bit of that detail mentioned Hopefully you don't need to take it out, but can just add a new deck over the existing one.

    We just leveled two of our main floor rooms with the rest of the main floor last week. This part of our house was built in the 1800’s and the floor was solid yet over time with settling and maybe kids or animals severely scratching into the old floor boards used as the subfloor we had to make our own shims. Doing this we built up the floors leveling them with the rest of the main floor. It took time and plenty of patience however it doesn’t just look better but walking through these rooms even feels better.

    Just remember when measuring to include the thickness of your new “sub”floor so you’re not making it higher than the other floors once it is laid in place.

    Keep an eye out for moisture ! You could end up building a mini sauna if the air flow ain't right
