Floor plan design for a passive single-family house ground floor

hm,
First of all:
With a floor area ratio of 0.1, you are allowed to build over 120 sqm and probably with you the second indirect floor area ratio counts, so you are allowed to seal this number again for outbuildings including paving of the driveway.
That means: house including terrace max. 120 sqm.
Outbuildings including driveway and paths 120 sqm.
One-story is very likely not given here, as the roof terrace counts proportionally. I’m not calculating anything now, I’m just going by gut feeling.
Then my question about the width of the plot because of the setback areas: I assume it doesn’t fit.

About the design itself: little living space on many sqm. The spatial proportions are missing here. Large storage 6 sqm... kitchen minimal 11, the space in front useless. Freezer huge, otherwise 40 sqm remain downstairs, rather uncharming.
Upstairs Kaho already mentioned.
Otherwise: stairs at the dirt entry area, no real closet area for a standard closet in the bedroom, child next to bedroom, ballroom as bathroom...

You should first look at model houses in your area to get an understanding of sizes. Then of course how passive houses are built. Whether the effort is even worth it.
Also the roof terrace? Who needs that, when there is a garden?
And a balcony, which can be used by both parents and child... you might as well just put a window between both rooms... saves the explanation. [emoji6]
Have you ever thought about how much you can and want to spend? The bank likes to have two debtors with bigger loans...

When I open the pdfs, completely different floor plans appear... Very strange

Try clearing the cache :)

If I read the BauNVO1962 correctly, in addition to the 0.1 for the house, I am allowed up to another 0.1 for garages and covered parking spaces, and everything that falls under "Nebenanlage" is not counted at all.

(5) In Kerngebieten, Gewerbegebieten und Industriegebieten können eingeschossige Garagen und überdachte Stellplätze ohne Anrechnung ihrer Grundflächen auf die zulässige Grundfläche zugelassen werden. In den übrigen Baugebieten werden solche Anlagen auf die zulässige Grundfläche nicht angerechnet, soweit sie 0,1 der Fläche des Baugrundstücks nicht überschreiten. Absatz 4 findet keine Anwendung.

Here, the second sentence applies to me, because WR, that is pure residential area.

(4) Auf die zulässige Grundfläche werden die Grundflächen von Nebenanlagen im Sinne des § 14 nicht angerechnet. Das Gleiche gilt für bauliche Anlagen, soweit sie nach Landesrecht im Bauwich oder in den Abstandsflächen zulässig sind oder zugelassen werden können.

(3) Balkone sowie bauliche Anlagen und Gebäudeteile, deren Grundflächen nach § 19 Abs. 4 und 5 nicht angerechnet werden, bleiben bei der Ermittlung der Geschossfläche unberücksichtigt.

I am happy to be corrected if my legal interpretation here is not correct. After all, I am only a layperson in this area.

That’s enough about building law for now...

I do not need the balcony, I can simply plan a roof surface here. I need the setback only for the recessed top floor. And I thought as a roof terrace / balcony it might still be somewhat reasonably usable..

Oh yes, regarding distances, if I have roughly calculated correctly, I have 3.5 m on the right and 5.5 m on the left to the property boundaries, that should fit....

There is a building use ordinance, which I believe is amended every year (but I could be wrong) and for Lower Saxony a state building code, the last one from 2012. Please excuse me if I do not check your stored quotes now, from what context they come.



Furthermore, you are only allowed to build up to 9 meters on one side of the property.... I don’t know now if you intended that on 23 meters.

Therefore, I can only advise you to follow my first advice in my first post here, furthermore just put your draft away forever - it is not necessarily thought through enough to achieve improvements with small changes. Here’s to a new start :)

I wonder where I should store things if I, for example, give up the storage room... There is no basement, no attic... If I imagine that I currently have a small basement in my apartment, about 10m², which is more or less full, starting from suitcases to drink crates to Christmas decorations...

In the bedroom, there is more than 2.5m of space behind the door for a wardrobe, that would be a 5-door Pax, for example. How much should I plan for here?

I still need to check the kitchen dimensions to see if they match what I have planned for the kitchen equipment; at the moment, I just can’t access the kitchen planning :D

Regarding the budget, I intend to do a lot myself, either fully renovate or maybe even as a kit... I have the plot, and it is debt-free. I think the house should cost around 25,000, a very rough estimate; I will handle the financing alone, but since I own the paid plot in the Hamburg metropolitan region and have a well-paid and secure job, I don’t think there will be major problems; at least, those were the first non-binding statements from several financing providers. The costs will, of course, vary depending on the extent of self-work and, of course, the construction method, etc.

There is a land use ordinance, which I believe is amended every year (but I could be wrong), and for Lower Saxony a state building code, the latest from 2012.
Please excuse me if I do not check your inserted quotes now regarding their context.

They come from the land use ordinance of 1962, because according to the building authority this one is valid, since the development plan came into force in 1964, and the one valid at that time still applies.

Furthermore, you are only allowed to build up to 9 meters on one side of the property.... I don’t know if you intended that with 23 meters.

I cannot confirm the 9 meters. The minimum distance according to §5(2) Lower Saxony Building Code is 0.5H and at least 3m. With a height of about 7m, the distance according to my calculation would be 3.5m.

Therefore, I can only advise you to take my first advice in my first post here, furthermore just to put your draft away forever – it is not necessarily so well thought out that minor changes would lead to improvements.
Here’s to a new start :)

:D Several people have already looked at my plans, but so far no one found them that bad :D I find that interesting.
