modern Bauhaus, lots of glass, 170 sqm ground floor/upper floor, currently in phase 3

If the building authority doesn’t want to approve it – and there would be plenty of reasons for that – tough.

No, I’m afraid the building authority won’t buy that the OP is appealing to his own decency in moderation.

This house (whatever style you may call it) definitely upgrades the residential area. By the way, every new house does that.

In my opinion, this house would be a precedent here in that sense, as it would provoke without giving anything back in terms of upgrading. I emphasize that I see this completely separate from the question of whether someone can distinguish between Bauhaus and Hornbach or even spell Stiehl correctly. Someone here wants to put my namesake into a china shop; the silly geese shouldn’t be so xenophobic, the fox is so cute. Even if it were a pure Bauhaus – it would not fit better into this residential area than a McMansion Hell (because in ensemble with the surroundings it still forms one).

what’s lecturing about it? As always and so often, it’s a matter of taste and that taste varies completely within some decades, that should be clear.

You’re right, "lecturing" is the wrong word for such a demonstration of the most brutal possible contrast. Your house, by contrast, is a modern interpretation in white of what your neighbors built five decades earlier in yellow-gray. That’s why it’s not an alien body, even with not precisely symmetrically parted trash cans :)

This house (whatever style one may call it) definitely enhances the residential area. By the way, every new house does.

That may certainly be true, that here and there a new and modern house enhances a residential area. But unfortunately, quite often the opposite is also true, namely that the surroundings can devalue a new house.

I think there's really no need to argue here: either it gets approved or it doesn't! End of story.
Personally, I also find the upper floor in the exterior view quite well adapted in color to [Satteldachhäuser] - that could be the right path for approval and above all the adaptation to [Satteldächer].
Nonetheless, you live inside and don't build a house model that looks great from the outside (in the eye of the beholder) but barely offers corresponding functionality inside.
It's simply lacking in utility rooms -> storage, storeroom, utility room... and if you have stuff for 5 people (we don't know how old the others are), I would voluntarily choose the [Satteldach] variant.
However, the OP seems quite resistant to advice when it comes to functionality.

This house(.....) definitely upgrades the residential area. By the way, every new house does that.

So every homebuilder can feel like a missionary who has painted over the previous misery in mouse gray....? Aha - I guess I still have to train myself to have that kind of self-confidence. I have traveled a lot, for years mostly in the East, where in the 70s-90s there was no money or no value was placed on certain things. But now when I drive around here or in my former homeland, I am no longer sure whether this type of building has actually meant an upgrade for a region. When I see these areas that have neither seen excavators nor style-hungry homeowners with better salaries, then I am happy about it..... until I turn the corner and see the same again. I have never come up with the idea that my house could upgrade the area. On the contrary, there was usually a meadow before where now hundreds of L-shaped stones, trampolines, and metal fences stand. That strikes me especially....... the desire for a fence!

oh come on guys, here it's partly acted as if the only reason for the house is to really show the neighbors :-) And not because someone likes the style. The OP hasn't responded anymore either. As mentioned, I assume that the preliminary building inquiry has been submitted and it will be approved. But maybe I'm wrong and the family will fail :-) I'm afraid we won't find out anymore

come on guys, here it is sometimes acted as if the only reason for the house is to really show the neighbors :)

Well, if that were actually the driving force behind building your own house, then it probably couldn't be solved with medication anymore.

Nevertheless, you live in a community and therefore should not only maximize your own advantage or even force it......that was what was discussed here
