We plan to take down an interior wall and combine two rooms. We're hiring out the work but it's good to know whether the wall is load-bearing or not for permits, etc. I made a peephole and can confirm that every 60 cm there are two studs (one against each wall) measuring 70x40mm (see image). Does this mean the wall is load-bearing or are the studs only there to support the wall itself?
We live in a 1.5-story Sidensjö wooden house from 1992.
