I have a step down living room. How can I make it level with the rest?

How good are you at construction? Depending on where you live, you might need to pull a permit as you will be making structural changes. What is the flooring in the area now?

Honestly, this is something I would call a licensed contractor in to do for you. Don't forget, your family, friends, kids, pets will be walking on this constantly. It must be completed safely and to current building codes.

Honestly this is not a diy you will need to hire a contractor,in the mean time is it worth it

Photos would help. How much lower is it than the rest of the floors? How big is the living room? Are the ceiling heights the same? It is a major undertaking. Involves some construction, but nothing structural so permits will not be needed. Laid out as the existing floor, it would meet building codes. I have raised floors in homes, garages, enclosed porches, and had no problems.

William is totally correct. It is a major job for construction people but can be done to bring the floors level with each other. Call for some estimates and suggestions. Flooring companies in your area can assist with estimates, suggestions, etc. Someone will have to build your old floor up with 2 x 6's or whatever to bring them up, then put new flooring on top of plywood underlayment. It will be quite a job. Call professionals for this one.

Are you sure you want to do this? I'm remembering a friend of mine who lived in a beautiful home with a dropped-down living room - it was lovely and set it apart from the other subdivision homes on the street. Perhaps, it is a hazard (??) for a visually impaired resident currently living in your home? In which case, I understand. If it isn't, I'd never think of changing it!
