first thoughts are that the house wasn't made with a load bearing wall there, it isn't necessary. You might top the walls with styrofoam, but ecologically that stuff isn' cool. but wouldn't the free floating single end of the internal wall studs make that wall a bit weak?You would put a rubber boot of sorts around each stud and connect them to the top and bottom via glue. The stuff is gastly expensive but goes by the name of zorbathane.
