We have a ranch type house that has a sunken living room that we would like to raise to the level of our other floors. We intend to have hard wood flooring installed over it and the other rooms around it. Ceiling height is not a problem. The floor needs to come up about 5 3/4 inches. I figure that some ripped 2x6 's and some 3/4 inch tongue and groove OSB would do the trick. The big question is what way should the 2x6's be oriented and should construction adhesive or anything else be used between the old subfloor and the 2x6's that will be put down? The current floor joists run East/West and the new Hardwood flooring will be put down North/South. A contractor told me to just put the 2x6's down North/South to make hitting the current floor joists with nails easier. Will this pose problems with the hard wood flooring? Is there a better/proper way to do this?
Thank-you, thank-you very much.
