Load-bearing wall?

[jansen]

Hello!

I wanted to make the opening between the living room and kitchen larger. It is currently 1800mm, and I would like to open it to 2400-2500mm at the minimum.

The house is a single-story Nordkalotthus type built in 1980 (in Norrland). It stands on plinths.

The wall is built with double 45x70 studs on cc 60. Span 8000mm.

Is the wall load-bearing, is what I'm wondering. And what dimension of laminated beam is needed to support it in that case?

The wall is guaranteed to be load-bearing. To be able to size a replacement beam, a dimensioned section is required. The columns on which the beam must rest cannot land just anywhere. Therefore, a drawing showing the foundation structure and the locations of the piers is also needed. Information about the snow zone is also required. It is not certain that the cost of this intervention corresponds to the benefit of it.

Thank you for the reply!

There were no detailed drawings available when purchasing the house. The snow zone is 3.

What could the cost be in the worst-case scenario? Are we talking 10'+ or 30'+?

Then you have to estimate on the high side. How wide is the house?

The material cost is a couple of thousand kronor. I don't dare to have any opinion on the other costs. They depend a lot on local conditions.

Ok, understandable. The house is 8 meters wide.

A 2.5 m long glulam beam with dimensions 90x315 mm is sufficient. It should rest on 90x90 mm glulam columns.

Ok, thank you very much for your help!

I will have a carpenter perform the work when it's time.
