Is the plot suitable for a narrow house for 5 people?

Talking to the building authority will not be necessary (since the plan is clear in this regard and does not require exemptions) and therefore makes little sense, as the neighbors will be the ones to talk to (and the building authority may only give them your contact details, but not the other way around). Network among yourselves, it’s not difficult.

With the usual suspects, this—hence why the models are so similar—is cleverly tried and tested. The best thing for the children, besides age-appropriate playmates on the same street, are above all parents who are not kept awake at night by capital service payments for a stylish Neuschwanstein. What Jürgen Rüttgers once bluntly called "children instead of Indians" essentially requires homeownership construction companies with offers for families that secure the wealth of retirees. An economy cannot live on a handful of Geissens. 140 sqm for a family of five is not "(a)social housing," but bread & butter architecture for everyone. Affordable housing costs and golden faucets are "natural enemies" of each other.

Great - thanks! That definitely makes the west property attractive - if it weren't for the 140k price difference.

I basically agree with you, but the access to the second bathroom and the designated storage space remind me of 1980s floor plans, when people only owned a third of the stuff they do today.

No, quite the opposite. Did I express myself incorrectly?

The floor area ratio refers to the living space of full stories. Attic conversions can be done, but if there is no full story, they do not count.
If you cleverly divide your 7 x 12, you can make a parent floor in the 30-degree roof. Note that the ridge direction is prescribed there. So the roof will be spanned over the 12 meters. I think you don’t necessarily need dormers since you have gables.

Well, there has to be a punishment, if only for the obviously extremely sloppy research: ... because it's precisely there that you find the exact model you need everywhere presented as a bestseller. Although as a classic non-detached semi-detached house, having one more window side is no harm. By the way, the usual suspects are mostly also GU, but in the projects suitable as models here, they are mostly (only) BT. I can easily imagine this seemingly detached semi-detached house, as it will probably only be a set-apart third twin to the semi-detached houses standing directly next to it (however, in the development plan excerpt I see neither contour lines nor clearly recognizable usage template allocations). I agree with the assumption that the garage is practically a twin clone of the neighbor's garage – and also that the roof pitches of the main roofs are to be adopted and thus coordinated with the neighbors of the semi-detached house next door. But with the projects of the usual suspects, this is usually the case as well, so you will be able to visit dozens of examples of concrete realizations. And now you probably have to read the Goalkeeper thread all the way through. I had hoped someone could finally pick out only the successful house design there. Sorry .

Funny enough, in the example in post #30 ( : where does this come from?) "Bathroom 2" is even equipped with a bidet – (not only) unusual for this class of house and in my opinion anything but junk.
