Hi, I also want to support the Wall plate, with no loss of height. It was an outside toilet, with washroom, that has got integrated into the house, and I want to put window/doors in. I have just spoken to Catnic, and as said, they need bricks above them for integrity. I have also spoken to steel suppliers, who were encouraging, that an 'L' shaped angle cupping the wall plate should be ok. This needs to pass the building inspector, is there a way of getting calculations, that would help? Or any advice please C
