Install a walkable ceiling, thickness of the rafter wood

yo,

I understand that it was meant seriously. from me too, I'll put the old beams back on or smear them again and that's it :)

regards

Hi,

I have the same question. I also want to convert a timber-framed house. We also want to make the ceiling load-bearing and also convert it. Different laws apply here than in NRW.

Therefore, I will hire a carpenter and a structural engineer. They should calculate it and tell me what needs to be done.
