I have a sunken living room that drops approximately 11 3/4" to the lower foundation. This is where the existing drywall stopped, and carpet was glued to the foundation wall and covered with trim where it meets the drywall. The existing drywall is not flush with the foundation but overhangs from 1/2" in some areas to almost flush with the foundation wall. I've pulled the floor carpet and the wall carpet off to install wood flooring. First Option is to install 1/4" drywall and mud up so it blends with existing drywall and and match texture. The flush areas would just be mud and texture. Second option is to install 1/2" plywood (cut to size) to foundation wall, and add trim where it meets existing drywall and add baseboard at the bottom. Concerns: I heard the mud may crack, is that certain? Will it be reliable? How would the wood be attached? Liquid Nails? Work will be contracted out. I hope this isnt confusing..

Thanks...

You don't want either material attached to the block wall. Any moisture can wick into the material.
This is an odd setup. Can you post photos?

You need to check if there's moisture emminating from the concrete before you decide on a solution.
Take some plastic sheeting and cut it into squares and tape the pieces to the concrete around the curb.
Seal the perimeter completely. Leave it for a few days and see if moisture condenses under the plastic. The results will dictate a posible course of action.

possible solution

for a seamless look (and depending on your style and decor), I would put up a bead-board wainscotting with a chair rail to top it off. that would blend the differences between drywall and lower concrete foundation wall over the height of the bead-board material (about 40-44"). bead-board is reasonable cheap and the MDF stuff is ready for paint.

No, no, no, Andy! Sunken floors are great for falling over in the night; I know, I have one because of a head room issue w/ an addition. If I could have avoided it, I would; just more damn stairs to deal with. To the OP: I sure makes transportation easier if you have one level, and may avoid some of the problems you are having. Any way to install a 2x floor joist system w/ a plywood top and maybe PEX pipe for heat while you are mucking around? Good luck. j

Sunken living rooms were very popular in the 60's and 70's and now have made a huge come back. It's one of our favorite features in the house. We love our living room and would never raise the floor. In addition, it would be impossible. We have doors leading outside that are the level of the room.
Thanks for the replies.
