Cost estimation per square meter of living area for a hillside house with basement and garage

Submit a preliminary building inquiry as a primary residence with the neighborhood as the justification. Let's see what happens.

That will definitely be rejected. They are quick with that.

That is the only thing I still believe in at the moment.

On the one hand, you confirm the 2500sqm, assumed by @hanghaus2023. A floor area ratio of 0.1 and your assumption of the floor area, however, suggest a 1170sqm plot.

I already explained that this does not necessarily represent a contradiction: excluded partial areas from construction are not included in the basis for calculating the floor area ratio.

When asked where the plot is located, you say something about Bielefeld. But Bielefeld is not in Lower Saxony.

Only Schrödinger experts can probably determine the exact location of a city that does not exist ;-)

Why and what should one want to achieve if the development plan, apart from the fact that it is a weekend property according to Par10 NVO, actually has many or common possibilities?
As a municipality, I wouldn’t want to change anything either, because 0.1 for an oversized plot should be sufficient. In addition, they just don’t want to clutter this edge section with oversized houses.

Here again a text markup concerning a note related to the development plan.

According to the development plan, a full storey is allowed. If you plan a , then you can also convert it. Building authorities are not interested in so-called "half storeys" because they do not exist under building law. So they cannot ban or prohibit them either.

This statement from the district office was clear that the existence of converting the attic is not approved. And so we did not consider it.

Since you are very sparse in communication here and do not communicate concretely (a plot ratio of 0.1 is made into 117 sqm of floor area), one must honestly assume that you perhaps asked the office the wrong questions and thus evaluate the answers wrongly for yourself.

On the one hand, you confirm the 2500 sqm, accepted by @hanghaus2023. A plot ratio of 0.1 and your assumption about the floor area however indicates a 1170 sqm plot.

New: the plot already has 2500 m2. The note regarding the development plan still exists. However, only about 1200 m2 are buildable due to the prohibited zones.

Are you afraid that someone here will buy your bargain plot out from under you? I assume no one here is interested in taking away the weekend property from a user who asks one or two questions here.
Have you ever thought about why the plot still hasn’t been sold?

That’s exactly the point. And it’s no bargain at all. I actually don’t need such unqualified comments. There must be a reason why I don’t throw cheerfulness along with all information around me. However, this does not belong here.

I am fully aware of the plot and the conditions! Period.

Why start planning without first calculating the house price based on the living area? Or questioning the development? It’s no secret that building is expensive?!

In my original calculation, we would have had enough financial means. However, the plot was significantly smaller and both original plots have now been sold.

What remains is the big secret of the building permit with a basement. And the clarification was the whole point.

We have now had it for quite some time. Only the plot negotiations are proving very tedious.

I probably underestimated the basement in total costs somewhat. That’s why my calculation worked out. Also, the incidental building costs were estimated somewhat lower overall.

But that’s exactly why I’m here, right? And I am also grateful for help.

Maybe something should be clarified: What the LK wishes for is initially irrelevant. Only what is stated in the development plan is binding. So if you submit a building application with a developed roof, the LK must provide a reason to reject it. Since there isn't one, it must be approved. Otherwise, it can be legally enforced. To live there temporarily, however, you must prove your primary residence. But you already know all that.

I would not know, for example, whether the municipality is obligated to provide waste disposal for such properties? It would also be interesting to find out about water disposal. It is not obligated to approve a KKA or keep the road passable for a disposal vehicle.

To temporarily live there, however, you must prove your primary residence. But you already know all that.

Exactly. All 10 houses have their primary residence there under the guise of tolerance.

For example, I wouldn’t know if the municipality is obliged to ensure waste disposal for such properties? It would also be interesting to find out about water disposal. It is not obliged to approve a KKA or to keep the road passable for a disposal vehicle.

All buildings are fully developed and accessible via the municipal road that has been fully expanded contrary to the development plan. I never understood the thing with the attic either. But the clerk at the district office explained it to us like that in the preliminary talks.
