How do I build side support for a bench seat in a breakfast nook? I want to build a bench seat in a breakfast nook in my kitchen but I do not want the seat to come out the full length of the side walls. I want the front edge of the seat to come mid-length of the side wall. The side walls are drywall and there is studding at both corners. The side walls are just over two feet, but I want the seat of the bench to be about 18 front to back. I need support in the walls for the frame of the bench seat. Is there a way to build support mid-length in the side wall without tearing into the drywall and studding? Thanks.
