Building housing on existing land ownership - ideas wanted

H

I'm not the OP ;)

Should have added to whom my questions are addressed. Just wanted to point out that it is (almost) impossible to build outdoors.

If you are located in the outer area (one can almost assume that since it is an old farm), the likely answer to all options is: Not possible, as it cannot be approved.

You will get certainty by talking to the authorities or submitting a building preliminary request.

P.S. Why do you see saving potential in your options – costs will be identical? What is the difference in ongoing costs? Do you have higher flexibility now?

If the costs for all options are higher than buying a building plot + new build, of course it wouldn’t make much sense. But I assume it will be cheaper(?). In an apartment, you are relatively flexible if you change job/location or want to downsize/upsize.

Who is building there? Keyword "Altenteiler"

Read §35 of the Building Code, then you will know what is allowed and what is not. Is it also a §35 area or rather a §34? Have you already spoken to the building authority?

Is there a strict definition of outer area? The house borders a federal road and this in turn borders a very densely built main road (however that is already the neighboring municipality). On the other side, there are 3 neighboring houses directly next door and another 3 behind the house (in the direction a new building would go). The neighboring plot, however, was rezoned from meadow to building land about 15 years ago and then built on.

So it is not a core village area, but also not a lonely house on a lonely meadow.

In the area, you see many new buildings next to farms, but these are mostly these retirement houses that farmers can pass on to their children. There was such a case in the family as well.

What about the other 2 building parts of the farm (apart from the barn)? Are they inhabited?

The house is inhabited, the garage is used just as that.

But I assume that it will be cheaper(?)

Just tell me exactly why the new building next to the old building will be cheaper than building an identical building on another plot. I never said it would be more expensive.
Do you already own the yard or do you have to buy the plot like any other plot? Is the building site at the old building already developed (internal development) or does it still need to be developed like any other plot?

Is there a fixed definition of Außenbereich?

No, there isn’t. It’s easier to say that everything outside of "Innenbereich" counts as Außenbereich – meaning where there are development plans or where due to closed development it is a §34 area. The aim is to prevent scattered development, which is why there is Außenbereich where building on a plot is not allowed (privileged measures or except as per §35).

Please upload a plan of the plot including the surroundings.

The construction itself will not be cheaper, and in the case of the barn, possibly even more expensive. However, the land costs or possibly part of the development costs are eliminated (since it is owned, nothing has to be purchased).

The house is fully developed. I don’t know whether the barn can then simply be connected or needs to be newly developed (with full costs as with new construction).

I have a plan from BayernAtlas, is that sufficient? Otherwise, I can photograph the regular plan, but in my opinion it contains less information. I have marked the two possible plots (1 and 2) in yellow, whereby 1 is clearly preferable and 2 is already in the neighboring municipality. The extension would be in red and the barn in blue.

Based on the pictures, it looks like an outdoor area. In your municipality, there is no development plan for the area or no outdoor area statute. Call Siegfried at the building authority. Extension -21 and just ask. You won’t get better advice here at the current stage.

P.S. The barn and the new building will probably need a completely normal internal access, like any other house. You are only saving on the land.

I wanted to first approach the community with something more concrete. If, in the case of a new construction or expansion of the barn, you only save on the land, but not even a part of the development costs, in the end you save only a few thousand euros. Thus, the extension would actually be the cheaper option. But these are already good pieces of information.
