Floor plan of a single-family house, 2 floors with basement, approx. 190 m², plot approx. 440 m²

P.S.: just now I actually forgot to express my amazement at the bitten-off northeast corner of the ground floor. The design reminds me a little of a template from the Massivhaus Mittelrhein program.

: you have to find a place for the outdoor stairs somewhere. And I've seen that a few times in real life and actually find it quite cool, as an entrance canopy. No, it's not from a template of this general contractor. In fact, I exchanged a few emails with the apparently sales manager and spoke with him on the phone, but when it came to arranging an appointment, there was no response to my emails or calls... When multiple callback requests go unanswered, then they haven't earned our money.......

Be glad that it is still early enough to dissuade you from this folly. Besides, waiving an architect and a preference "pro GU" are two completely different things. https://www.hausbau-forum.de/threads/Abstandsfläche-rlp-bei-einem-34baugb-grenzbebauung.39892/#post-512520 By the way, private border development agreements have already been discussed there, which, in my opinion, are somewhat interpreted by the building authority as a kind of salvatory adoption of setback areas. Possibly, it also plays a role in the background that Niederbieber was not yet a district in 1962.

The nice gentleman from the building authority clearly said at the appointment that this border development agreement from 1962 is a private contract that we have nothing to do with and which also has nothing to do with building law. Therefore, the current facts must be taken. He built on the border, we must keep a 6m distance with a residential building. Period. If he says so, we accept it as it is. He will later put the stamp on the building application. Or not. So we plan exactly as the gentleman from the building authority specifies. Garage to the right next to the neighbor’s house. By the way, we have meanwhile spoken to the neighbor. For him, the window is not important because it is in a corner of the living room, and he has a large glass front at the back. Therefore, our garage will definitely go there.

One of the general contractors explained the price to me as follows:
He said that for the bricklayers it doesn't matter whether they are building 2 or 3 floors. The interior finishing is the same with the upper floors. The price of 342,000 is a fixed price. Without the extras already mentioned in previous posts. They have a contractually agreed construction start, fixed price guarantee, contractually agreed construction period, all usual insurances... Maybe ytong is just so cheap and quick to build and that's why the costs are low?

But as I said, we will also get other offers. Let's see where we stand.

The nice gentleman from the building authority clearly stated at the appointment that this boundary construction agreement from 1962 is a private law contract, which we have nothing to do with and which also has nothing to do with building law. Therefore, the current facts must be taken. He built on the boundary, we must keep a 6m distance with a residential building. Period. If he says so, we accept it as is.

Well, he really has to decide a bit whether the contract is also effective vis-à-vis the authority or not. At the time of the neighbor's building permit (incidentally from the exact same authority, which used to be located in Niederbieber) it was apparently accepted that the neighbors jointly agreed on a (later / time-shifted) duplex construction. By the way, I am currently unsure whether you received my email reply from September 7.

Well, he really has to decide a bit whether the contract is also effective towards the office or not. Back then, with the neighbor's building permit (by the way from the exact same office, which used to be located in Niederbieber), it was apparently accepted that the neighbors agreed on a (later / time-shifted) semi-detached house construction together. By the way, I’m currently unsure whether you received my email response from September 7th.

: yes, we could also extend. But we do not want to extend. So, extend or 6m distance. Why should I start discussing this?? He said it like that and we accept it and plan accordingly. To be honest, I do not understand the problem.

: yes, I got the mail. But as I said, it is out of the question for us. The site is quite interesting.
