Help needed - Real division of a narrow plot

Stop, I can't edit the post above (pretty badly done here). There is no development plan, there is apparently only that one rule in the documents.

One full floor.

The house as I imagined it has:

Ground floor approx. 78m²
Length of the building: 13.5
Width of the building: 6.5

Can we then build the upper floor with 2/3 of the ground/full floor in the same width and height but adjusted length? So then with 52m²?

Many thanks and best regards

In the outdoor area (i.e., without a development plan) you must/can adhere to the existing buildings, always clarify details with an architect. In principle, your idea should be feasible, but in these areas it is always an individual permit.

I have read 2/3 or 3/4 here in the OG. According to my research, it is 3/4, am I correct? That would be a few square meters more, after all. :)

Hello ,

unfortunately, I don’t have telescopic eyes to look from here to NDS to assess the neighboring buildings. Above all, no one can reliably say what the caseworker who is supposed to approve the building permit will say about it. And you have to get past him – if necessary, even with a lawsuit. Yes, 3/4 may be possible. But if other criteria are violated, all of that is irrelevant, and there are at least some of those points.

So for the 10th time:

1. You need an architect. No architect, no building application. No building application, no house.
2. You need a surveyor. Without a surveyor, no subdivision and building survey, (possibly) no staking out during the construction phase. Without subdivision, no separation of encumbrances/loans and thus at least a problematic property and loan situation, which should always be avoided as much as possible. If the (parents-in-law) do not cooperate, you won’t get a loan without subdivision either. Therefore, the question of 3/4 or not is also clearly irrelevant.

Architect and surveyor together can explain to you on the spot within 30 minutes what is possible and what is not. No one here in the forum can do that – unless you commission a specialist planner from the forum to look at the situation on site. The costs for that are exorbitant depending on the travel – local specialist planners might even do it without extra costs. I can put you in touch regionally if you want.

Otherwise, you won’t get an inch further in your case.

Thank you

I am asking here "in between" to also prepare myself. We have an appointment with the architects on Wednesday. I have already spoken to the publicly appointed surveyor by phone but have not yet invited him to the property. We want to do that after the visit to the architect. If you can recommend someone to me.

Best regards

Hello everyone,

we were at the architects yesterday and they also have a surveyor who would work for us. This is now arranged, we will also obtain a second and possibly a third offer.

In yesterday's conversation, we received the information that the wall thickness is about 40 cm and then pipes etc. can/may be laid inside. This looks better and was recommended compared to thin 25 cm exterior walls. However, with our narrow house, the wall thickness plays a big role. The thicker I choose it, the less space I have inside. That means with 40 cm on each side, only 5.7 m remain from the 6.5 m width. Sure, a few more centimeters will be added, so I will probably have to subtract 1 m!?

Can the experts here possibly recommend massive construction methods that would work in our favor? The last solution for me would be to increase the house width from 6.5 m to 7 m.

Best regards & thanks.
