Cutting out wall studs to make doorway.
Background info.The house is typical weatherboard with hardwood frame built in the 50's. 2.7 ceiling in the original house, 2.4 in the extension. No trusses in the roof, it is rafters. The picture is taken from inside extension that was done in the early 80's that I am now gutting and redoing.
I wish to put an opening in the wall starting from the right hand side of the picture which shows the wall from the old extension side (which used to be the back of the house with weatherboards on it).
I will not be touching the end studs or top wall plate. I would like to take out 4 studs, which is exactly the width of the timber cross brace fitted, so that would have to go as well as the bottom wall plate. The opening is to be 2030mm, and 2000 wide.
Would an F17 KDHW lintel 200mm wide placed over the opening and into the next two studs be sufficient, or 250mm?
The crossbrace I can place on the next section of wall to the left, Is this ok?
The bottom wallplate sits directly on top of the joist ends. Will I need to insert noggings between the overhang ends of bottom wall plate that will remain?
