Construction tips Vetlandahus 1947

[Nordic74]

Hello!
Does anyone know where I can find blueprints for a Vetlandahus from 1947? We have replaced the roof trusses and added a floor. If you go up to the attic and jump, all the floors in the house shake. A load-bearing wall has been added on the middle floor, but there is uncertainty about how the attic's floor joists are attached on the long sides. The joists are freestanding, and the old roof trusses rested on a wall plate and a beam about 1 meter in and do the same today.

Hello.

A bit late with a response perhaps, but better late than never.
Myrsjöhus bought Vetlandahus in 1957. They might be able to help you with getting a drawing or something similar.
Good luck.
