Development plan: Definition of attic

Hello forum!

We are considering buying a plot of land. We would like to build two full floors (ground floor: kitchen + bathroom + living room, upper floor: 4 bedrooms + bathroom) plus an attic (2 home offices). According to the development plan:
- Max 2 full floors, including 1 attic.
- FH 9m
- TH 4.5m
- Gable roof, roof pitch 25-48°
- Knee wall 1.5m
Are we allowed to build as we have planned with these specifications? What do you think?

Thank you in advance

No! Not if you want two full stories like in a city villa plus an expanded roof structure.

I initially wrote a "Yes" with a reason and a brief restriction here*

Then I read about a maximum eaves height of 4.50. In this regard, the second mentioned full story already refers to the roof (included). However, this can become a full story with a 150 cm knee wall and generous roof pitch - as stated. If there is still a small attic upstairs that could be converted, that is also allowed. Such things (so-called non-full stories) are not mentioned in [BPlänen].

*Is there a reason (e.g., slope) for this complicated construct in the development plan?

As you had planned, it will probably not work out. But you can also plan differently. So if the plot is otherwise suitable, I would not base the decision on the 3 floors, but on whether your space program is feasible.

Clearly no (the reason has already been correctly explained), I have marked the signal word for easy recognition in your quote. "TH" means eaves height, which, simply put, practically refers to the height of the knee wall from the ground floor slab. If the bedrooms are not supposed to be tiny rooms, the room layout seems to require an upper floor that even exceeds the ground floor in area. But the biggest mistake is probably having planned the house before finding the plot.

Sorry for the delay!!! And thank you for your response :)

No, there is no particular reason for this structure, it is simply how buildings are constructed in the area...

In your opinion, would the attic be practical or just a storage space?

Thanks!!

Basically, an attic is always practical if you have a good standing height. However, that depends on the DN and house dimensions.
