I am working to remove a load bearing wall between my living room and my kitchen. I removed the sheetrock and the top of the wall has 2x4 top and double plates that is perpendicular to the ceiling joists (load bearing give away). The opening will be approx 9 feet tall and 11 feet wide.
At either end of the opening, I am looking at 1 king stud and 2 jack studs and adding a lally stud under the floor in the crawl space under each jack stud location.
Living room is a vaulted ceiling and the room above the kitchen is a bedroom and closet. I am I looking at using 2x10x12 (2ea) with a 1/2' shim in between to brace the span.
Will this be sufficient for a header?
