Is the wall load-bearing?

[sprwl]

I am considering removing a wall between the kitchen and dining room so I can extend the entire kitchen.
I had a carpenter who went up and checked the attic and he considered the roof trusses to be self-supporting in that section.

Thanks in advance!

I believe the carpenter was right. There are no rafters resting on the wall in question.

Hi,

Thanks for the answer @justusandersson. I have a follow-up question. I'm considering connecting the bay windows on the upper floor, but I'm wondering if the beams need to be re-dimensioned in that case?




Thanks in advance!

I find it a bit difficult to assess this solely using this drawing. It's primarily the floors of the burspråk that are the question mark. Can you take a photo outdoors directly facing the burspråk?

Why take a chance. Depending on what you have under the floor, I think it's best to secure it.

Hi Byron,

Which question did you respond to and how do you think I should secure it? Not sure if I'm completely following.

@justusandersson: There was a bit of poor lighting when I took the pictures, let me know if you want pictures with better lighting:

The usual practice is that bay windows are supported by beams that are attached to the floor structure and extend beyond the façade line. I believe that's also the case here. It is not realistic to insert additional such beams between the two bay windows; instead, one must be able to utilize the existing ones in that case. If that is possible requires a calculation, which in turn requires better and more detailed drawings, preferably in plan.

I'm considering merging the bay windows on the upper floor, but I'm a bit unsure whether the beams need to be resized in that case?

Thanks in advance!

Not sure how you plan to merge the bay windows, but isn't it reasonable that the short wall between the bay windows is load-bearing and difficult to remove/relocate?

Hi Justus,

Not sure if I fully understand what you mean. I included the floor plan (K3) in a post above. There you can see that new "floor joists" have been placed across the regular floor structure to support the bay window.

Then on the K6 drawing above, it looks like they've placed two 5*200 beams at the far end of the bay window to support it?

I don't know if there's anything else you can see or if you have any tips on how I can proceed?

Thanks for all your help so far!

uncertain about how you intended to build the bay windows, but isn't it reasonable that the short wall between the bay windows is load-bearing and difficult to remove/move out?

Yes, that's kind of what I'm trying to figure out. At the same time, it's not that far that it needs to be moved out and relieved if necessary, I think. It's incredibly difficult to find a structural engineer willing to take on these kinds of tasks, so that's why I'm trying to sort out the basics first.

The floor joist drawing (K3) shows how the floor joists supporting the bay windows are positioned perpendicularly to the other floor joists and function as a cantilever construction. The absolute best would be if you can supplement with such joists in the space between the bay windows.
