Wall cabinets have a quiet and important job description: Hold heavy glassware and ceramics up in the air. Do not peel away from the wall—just sit there and look pretty.
Don't forget to add the drywall thickness to the kitchen plan dimensions for an accurate framing layout. Kitchen plans indicate finished dimensions, not rough.
When bridging an opening in the base cabinets, don't rely on the wall to dictate cabinet placement. Use a straightedge to align the faces of the cabinets on either side.
