It also allows for seams and plates to move along the top. If we don't install these plates, when the rafter's point load is in the middle of a stud, the single top plate can be weak. While a double plate is strong, but even with the 16-on-center being closer, a single plate is very weak. This is why 24-on-center can be weaker than 16-on-center. For a California corner, you'll attach an L. This three-stud corner saves on material, but doesn't allow space for insulation. Or four-stud corner allows more thermal bridging inside and outside of house and gives no room for insulation. If we change for this three-stud corner, this gives space to stuff insulation behind your stud. And these will butt up in the corner. All you do is frame it like normal, but this 2 by 4 will sit on the deck. For wall openings, double-check your required rough opening size and you'll need to frame in jack studs and your required header size. Shorter openings can get headers that have less depth. Once this opening gets so wide, your header will need to be taller. Depending on snow load and roof span, you might be able to use a 2 by 6, but if your area gets a lot of snow and your roof span is
