Hello forum, we are buying the house shown on the plan (currently two separate halves) in Lower Saxony and would like to make some changes in the rear part: A breakthrough will be made in the partition wall between the two halves (made of drywall). A door in the right house will be 'closed off' to become a wall. In the middle room, a wall (with an additional door) will be built to create a passage – it is best if you compare both floor plans (old and new). I ask for your advice: The fundamental question about the floor plan: Please confirm that the structural integrity of the house is not affected by the renovation, nor is anything else affected (fire protection?, etc.) – I am not exactly sure what else needs to be considered. Please confirm that in this case, the modifications of walls and doors do not require approval. Many thanks in advance for the answers and attached below are the floor plan of the existing property and the plan for the conversion and the most important points in the text Development plan/restrictions Plot size: 2000 Slope: no Floor area ratio unknown, interior renovation only Plot ratio unknown, interior renovation only Building window, building line and boundary Edge development Number of parking spaces: 2 Number of floors: 1 Roof type: flat Style: modern Orientation: east Maximum heights/limits: unknown, interior renovation only Further requirements: none Requirements of the builders Style, roof type, building type Cellar, floors Number of people, age Space requirements on ground floor, upper floor Office: family use or home office? Overnight guests per year Closed architecture Modern construction Number of dining seats: 3 Fireplace: no Music/stereo wall: no Balcony, roof terrace: no Garage, carport: no Utility garden, greenhouse: no Further wishes/special features/daily routine, preferably also reasons why this or that should not be included: none House design Who designed the plan: Originally planner from a construction company, THE RENOVATION is do-it-yourself What do you particularly like? Why? Size of the house What don’t you like? Why? Nothing Price estimate according to architect/planner: Not applicable Personal price limit for the house, including equipment: unlimited Preferred heating technology: gas If you have to do without, on which details/extensions - can you do without: Not applicable - cannot do without: expansion of one half of the house Why did the design turn out as it is now? Standard design by the planner Which wishes were implemented by the architect? House as bought The fundamental 2 questions about the floor plan briefly: Approval required? Structurally okay?

I confirm nothing and should be surprised if anyone here is supposed to confirm your concern. Structural integrity cannot be changed from a distance, and the intended use of a property probably also needs approval; who knows better than the authorities? [emoji6]

When it comes to floor plan discussions, it is about whether a design makes sense or not considering the wishes of the builders.

It definitely is not about an assessment of structural integrity from afar. You are in the wrong place here. Without an architect, nothing should happen on your end!

I don't believe that.

Lower Saxony Building Code Annex Non-permit-requiring construction measures:
12.1 Walls, ceilings, supports, and stairs, except exterior walls, building partition walls, and roof structures, in completed residential buildings or completed apartments ...

Even if my belief is wrong and it is a non-load-bearing drywall, it still remains a building partition wall, so the exemption from approval is excluded. "Office" and "tea kitchen" suggest a commercial use, which also must be approved.
The way the questionnaire is answered gives the impression of great ignorance, so I strongly recommend visiting the local building advisory service.

But it is stated like that in its legend in the AS-BUILT plan (see right side).

What is not stated there is whether the stud framework is load-bearing. But I assume that it is. Therefore, just proceeding without a structural engineer is not an option.

There is also no discernible difference in the plan between new masonry and demolition, as well as an outer wall about 1.20 m protruding into the building setback on the right side, parked in the second row. To put it kindly: I don't take the drawing at face value.

Please, those who only want to vent polemics like 'it is so', 'I don't believe it' or 'I confirm nothing' better not respond at all, your posts do not help in a factual way. Independently of that, thanks to all factual contributions.

So the partition wall is not load-bearing and consists of the mentioned drywall panels. As a clarification: I am not concerned with evaluating the statics remotely, but rather with

1. better understanding the drawing and whether this allows conclusions about the statics: so far I conclude: no conclusion can be drawn from the plan. Please correct me if anyone thinks otherwise. 2. clarification whether approval is necessary, and from this post I conclude that no approval is required:
