I am about to make quite substantial changes to the floor plan in the newly purchased house. In the picture below, I show three walls I want to remove, as well as a substantial section of the beam structure to build a staircase to the upper floor.
The three sections that need to be removed (310+225+140 cm) are, of course, part of load-bearing walls. The walls are the same as the other interior walls in the house, but there are base beams in the slab for just these interior walls. Additionally, the entire room marked with red lines should be removed, as the staircase to the upper floor is to go there. In the lower picture, I have drawn how I plan to replace the walls with a steel beam that is "hung" in cutouts in the existing walls.
I have no idea about the dimension of the beams, how much do they need to support? I have realized that these are load-bearing walls, and one cannot just start swinging a sledgehammer...
I would like some tips and comments; I understand that I need to contact a structural engineer to handle this, but it doesn't hurt to be well-informed before starting. If anyone has the name of a structural engineer in Skåne (preferably southwest Skåne) that they recommend, that would also be helpful.
Thankful for all the help!!
