Hello!
I would like to demolish 3 walls between the kitchen and the living room. The walls are about 8 cm wide and are not made of brick, concrete, or lightweight concrete. They are hollow. I have read about self-supporting trusses in the attic and that if so, the walls under the attic would not be load-bearing. I have been up in the attic and checked under the insulation and there is nothing resting on the walls, neither roof trusses nor anything else. Do you need to reinforce in any way if the walls contribute to the house's stability, or can you safely demolish them? I'm attaching pictures from the attic as well as blueprints. I would really appreciate any tips I can get.
Best regards, Christian
