Hello forum, we are purchasing the house shown in the plan (currently two separate halves) in Lower Saxony and would like to make some changes at the back:

A breakthrough will be made in the partition wall between the two halves of the house (made of drywall). A door in the right house will be closed off to form a wall. In the middle room, a wall (with an additional door) will be built to create a passage – it’s best to compare both floor plans (old and new).

I kindly ask for your advice:
The fundamental question about the floor plan: Please confirm that the structural integrity of the house will not be affected by these changes, and that nothing else will be compromised (fire protection, etc.) – I’m not exactly sure what else needs to be considered. Please also confirm that this modification of walls and doors does not require a building permit / planning permission in this case.
Thank you in advance for your answers. Attached below are the existing property’s floor plan and the renovation plan, along with the key points summarized in the text.

The tone in a forum.

So the partition wall is non-load-bearing

Wrong assumption. The renovation requires a permit.
