Demolishing partition wall - soil pressure a problem?

[Thomas Vxo]

I have a smaller (95 sqm) single-story house from -69 with a basement. We want to move the stairs to the basement to get more space in the kitchen. The ideal spot for the stairs, however, is just above a non-load-bearing transverse wall in the basement. It is the only transverse wall on that side of the heart wall.
Could it be risky considering the earth pressure to remove it? Is there any standard distance that partition walls should be at to withstand the earth pressure? The basement is almost completely underground. Can the problem be avoided by making a new one with lecablock or something similar?

Currently in the process of draining - if that makes any difference.

Any wise insights? /Thomas

Without knowing how the basement wall is constructed, it's hardly possible to answer in any sensible way.
If you google for the lättbetonghandboken, you might get some answers there.

OK. Thanks for the tip. The outer walls of the basement are not made of lightweight concrete. According to the construction drawings, they are made of concrete hollow blocks. We had two non-load-bearing interior walls in the basement that were made of lightweight concrete (blue concrete) which we removed.
