Hello everyone!

I'm considering enlarging a previous doorway to be open from floor to ceiling and wall to wall, but even though I've checked that no roof truss is "spliced" there, I'm still a bit concerned about how it looks.

The wall running along the left in the picture is load-bearing since the roof trusses are spliced there. Previously supported with a beam, hence the cut post.

I can understand the two vertical posts for the doorway and the horizontal one to attach the door, but what's the purpose of the extra post attached on the left side? It looks like this in several places in the house, specifically with an extra post above a doorway.

What is it for and can the posts be removed?
 
  • Wooden hallway under renovation, with plywood covering a door opening, a work light, and exposed wall studs. Construction tools and materials visible on the left.
  • Wooden interior with exposed beams and a partially covered doorway. White sheet hangs under ceiling, a board stands against the wall.
  • Wooden beams and joists at a ceiling corner with an unfinished appearance, showing overlapping wood construction and potential structural elements.
To clarify, it concerns the red-marked posts.
 
  • Blueprint showing a building layout with red-marked posts on interior and exterior walls.

How old is the house and has it been remodeled or expanded?
Do you have more construction drawings?

What do you mean by a spliced truss when it seems to be trusses?

It's me who doesn't really have a grasp of the terms! I mean that, based on the attached image, two lower arms overlap above the wall to the right of the marked posts, at the entrance.
This house's trusses don't quite look like the ones in the picture since there is also a longitudinal beam that the diagonal braces rest on, which in turn is supported by posts.

The house was built in 1946 but was quite extensively remodeled in 1986, among other things. For example, a new roof when a floor was removed.

When the house is so old that it was built before construction became standardized and has also undergone a significant renovation later, I recommend bringing in an experienced structural engineer who can examine everything on-site.

Yes, I'll have to think about whether it's worth the trouble for a larger opening!
But where do you even find an experienced structural engineer? Are these people self-employed consultants in building construction, or how do you find one?

I can say that rafters of the same dimension run across the living room after this wall, so it shouldn't be necessary unless extra support for the living room's rafters is needed.

I'm really only renovating to the extent that I'm leveling ceilings with slatted panels, etc., but in the living room, I know that the difference in the corners of the ceiling and in the middle was significant. In hindsight, this makes me wonder if these underarms are properly dimensioned. But at least the house is still standing.

Is he the one who offers to calculate portability for people? I know I've seen him in many threads during my searches!

Yes. He passed away a while ago. Rest in peace.
