Great, then I wish you good luck.

Thank you as well. I think you could manage with your budget. The heating/plumbing item is estimated quite high. I see potential for savings there. I find the house style very appealing, but the ground floor layout wouldn’t suit me. The idea of having cooking, dining, and living all in a row feels uncomfortable to me. But of course, that’s a matter of personal taste. Here is the layout of our ground floor at the final stage. The orientation is pretty much the same, but we also have a basement.

I really like your project. Thumbs up!

How am I supposed to understand this

Yes, you can clearly see some differences there. However, I mentioned your house more as an example of a house design that I consider a practical approximation of the original poster’s current plans, aiming for a less impactful integration into their building area. I also deliberately did not link, for example, post 9858 https://www.hausbau-forum.de/threads/haus-bilderthread-zeigt-her-eure-hausbilder.14011/page-1643#post-453294, but started with your thread to allow following the development. Not least because your house was, at first, not my favorite project and still isn’t, but it has evolved.

Also expect a rejection from the authorities; it doesn’t fit into the area.

Maybe combine it with a very flat shed roof. That would probably make the approval process easier.

Perhaps the color scheme, which does somewhat resemble a roof, could help.

Reconsidering a gable roof should be planned.

Regarding the so-called Bauhaus-style in a §34 zone from the 1970s with exclusively gable roofs so far, I can only say that we got approval without any inquiry. So it’s not impossible. Nothing ventured, nothing gained.

The municipality doesn’t enforce this rule just for fun.

and more (just as an example, please don’t take it personally)

I’m posting this in every thread now so that everyone finally understands 😉

The roof shape has NO (!!!) relevance to the §34 integration requirement! Please don’t keep confusing people. Because of statements like these here and elsewhere online, we had sleepless nights before the council meeting. It’s just completely unnecessary.

The unfortunately no longer active @Escroda, an absolute expert and professional specialist on this topic, explained it to me (too late for my sleepless nights) and actually to many others here time and again. And yes, that was also the case in the council meeting. The building height is usually the main criterion for decision-makers, followed by other factors. Just quote the full § or refer to court rulings, for example:

"...primarily offer the (absolute) size of the buildings according to ground area, floor area, number of floors, and height and, in the case of open development, also their ratio to the surrounding open space as a reference to determine the permissible extent of structural use"

So yes, judging by the pictures provided by the OP, the city/municipality could reject the application, but not because of the roof shape...

The inactivity of @Escroda and @kahoo is detrimental to the forum

@Nemesis For us, the roof design was definitely an important consideration. But I guess that’s supposed to be irrelevant if it supposedly doesn’t matter.
