A building inquiry before purchase?

I can’t contribute anything to the question itself. I would call the building authority myself or show up quickly. Of course, it can’t be more than a feeler. In any case, I wouldn’t trust a realtor.

I would call the building authority of the respective municipality and additionally the higher building authority in the respective district office.

I would try on Monday and see if I get a solid answer.

Btw: I don’t really consider the plot in Kirchseeon to be attractive in terms of location. There is quite a bit going on both on the train line and on the B304; it’s definitely not quiet there.

It is not very quiet because of the train, but I think there is some shielding since the train noise is very low compared to other places along the railway line.
B304 is far away and has no impact whatsoever. I stayed there for about an hour to assess the noise. When no train is running, it is completely quiet.

From experience, I can tell you that it doesn't matter what time of day you drive along there – it’s a drama! If you want to drive from there to Munich in the morning, you’re stuck in traffic, the same applies for going home at rush hour, and even outside rush hours it’s often stop-and-go. Eglharting and Kirchseeon are bottlenecks.

Yes, I agree. It’s always congested. I have a friend who lives there and you’re supposed to always use the S-Bahn for the daily commute to the office.
On weekends or after rush hour (from about 6:30 or 7:00 pm) it’s completely normal.

Of course, the answers vary depending on the individual property. Kirchseeon: it depends on which third party is meant: compared to Wust, it might be possible; compared to the island, I see the building envelope as supporting a semi-detached house in the sense of the project. I see 1236/3 in Gröbenzell as well buildable with a semi-detached house.

Thank you very much for taking a close look at the exact property.

For Kirchseeon, I am attaching the exact property. We have approximately ~13m width and ~17m depth within the building lines. I am not quite sure what the dashed rectangles represent?

Do you agree with the real estate agent for Gröbenzell? Could I really have a living space of at least 135 m2 per semi-detached house unit?

Is an oral confirmation from the building authority sufficient? Or should I always get an official confirmation or even consult an architect?

These are house symbols, and here probably to be read as (in my opinion, indefinite) indication of house axes or ridge directions parallel to the street.

270 in total for both, to be divided as you please. Even agents cannot manage to talk only nonsense 24/7.

May I also understand why you think 13*17 is not good enough for 2 semi-detached houses?

270 in total for both, to be divided according to free preference. Even realtors can’t always talk only about metal 24/7.

But is it correct that BGFl. corresponds to living area? I have read somewhere that BGFl. also includes basement, attic, terrace & garage (as in this attached graphic, all red, green and blue areas are included).

Where did I say that?

Ah, I understand now. At first I thought you meant that the building envelope on this property was not suitable.

I see the building envelope as speaking against a duplex in the sense of the project
