Hello

I've just started decorating the upper floor of our newly built 1.5 story Älvsbyhus. I had a small thought about modifying a roof truss in the future children's room to fit a bed in what is usually an attic space. The roof truss has a support leg approximately 1.5 meters in from the eave, which will remain as it is. However, I would like to modify one of the diagonal braces that runs from the elevated wall head and then diagonally meets the support leg. In my view, its function is to support the wall head. The idea was to place a beam on each side of the diagonal brace according to the image (I've only attached a thin batten to demonstrate this) and then cut it off. Alternatively, do this and add an extra with a steeper angle (45 degrees). I searched a bit and found another forum user who did it this way but also cut the support leg, which we are not planning to do.

What do you knowledgeable people think about this?

Attached is an image of my idea, an image from an older thread, and a sectional drawing.
 
  • Wooden roof truss structure in an attic, showing diagonal beams and support with metal plates, illustrating modifications for placing a bed in eaves space.
  • Renovation project in a 1.5-story house attic, showing modified roof truss with diagonal brace and temporary batten suggested for a child's bedroom layout.
  • Cross-section diagram of a 1.5-story house roof structure showing dimensions and angles for potential modification of a diagonal brace in a future child's room.
I think it seems a bit silly to cut a newly manufactured roof truss without first checking with the structural engineer.

Hi

Yes, you're obviously right, we'll see if the manufacturer can be of assistance.
