Floor plan single-family house, 1.5 floors, 2 children's rooms, 2 offices - is area usage optimal?

Unfortunately, the garage (east) will probably be significantly (1m) lower than the house. That will be interesting with the 3m height limit in BW.

At least it concerns the same boundary where the neighbor apparently has already solved this.

That's true. Today the updated offer arrived. In total, we are now just under 500k€, however turnkey including excavation soil class 2-6 (without disposal, as we need to fill up properly). Ancillary costs such as construction site setup, surveying, etc. are already included. Some ancillary costs (soil survey, construction power, building application...) of course still come on top.

Don't forget that the innocent little word "ancillary costs" here does not correspond to something on the scale of a Christmas bonus, but rather to something like the difference between cold and warm rent, or gross and net salary.

Kitchen recess: niche for groceries (not walk-in, but a compromise instead of a storage room, since ours is in the basement)

Sort of yes and no, you can do it – but then it is cheaper not as a wall, but more like a built-in cabinet (since it is only practical in a limited height range, and below and above should then be better usable from the other side). Overall I consider it a borderline crazy idea as soon as the kitchen planning becomes concrete.

Living area as a passage room: wanted by us, since we don’t often go from the upper floor / hallway to the kitchen.

That is one of the most curious reasons I've ever read here – just as a side note.

Walking back and forth to and from the kitchen area is pretty much the core of every sitcom.

The upper floor itself is nicely tidy and well utilized.

I would almost have agreed if it weren’t almost 98 sqm of floor area.

In my opinion, the building mass is also unfortunately placed so that the garden is maximally chopped up. I would rather go wider instead of deeper.

I agree – but I assume that the gable width came about due to height restrictions combined with the knee wall request of 220. All in all, a typical general contractor’s design. However, there isn’t much room in width if the black frame is the plot and the open area on the left side of the plan no longer belongs to it.

The floor plan reminds me of a semi-detached house. That will surely work, but the floor plan is neither clever nor special. I don't like the open-plan room, neither the entrance situation, where you stand right by the sofa with your groceries, nor the cramped kitchen with the niche.

This will be exciting with the 3m height restriction in BW.

True. But the established level counts, right? However, if you have to overcome a few steps to the house entrance, I would also plan or mark that immediately. Possibly a slight shift of the garage or house could result.

Niche for groceries (not walk-in,

I don’t understand. Groceries fit in a kitchen cabinet. For supplies, you go to the basement. And not walk-in? How do you get to it? A vacuum cleaner or mop also wouldn’t fit there.

hbar, but a compromise instead of a storage room, since ours is in the basement)

Intended by us, since we don’t often go from the upper floor / hallway to the kitchen.

If necessary, projector with electric screen in front of the window

You already have two children? Then you should know that one or another household member also wants to park in peace sometimes, whether in front of the TV or just to have some peace. If visitors come who don’t visit all residents of the house, where is the retreat? If you plan openly, you have to consider such situations and the personal development of other family members in the planning. A living room that is centrally located, planned as a passage room and thus offers no quiet area is poorly planned. That causes discord and dissatisfaction in the long run.

…
Basically, it is a solid thing. Unfortunately, I still cannot warm up to it. The kitchen is too cramped for me, the living room not cozy, the furniture in the dining area looks suspiciously small, the hallway too dominant. Hopefully, the bathroom upstairs will also be nice, and I don’t find the corner in the hallway very elegant either. None of that are deal-breakers, but somehow the spark of a modern house is missing for me.

I feel the same.

In my opinion, the building mass is also unfortunately positioned so that the garden is maximally chopped up. I would go more in width instead of depth.

I don’t think so. Each side of a plot gives a garden the chance for individual spaces (in the garden). The alternative would only be another boring townhouse. But as I also confirm: somehow the pep is missing now. Some don’t need it either. But then you can at least make sure it is optimal.

That's true. But what counts is the established level, right?

In BW, it is probably the changed level as an exception.

Don't forget that the innocent little word "Nebenkosten" here does not correspond in scale to something like a Christmas bonus,

Well, the large amounts are included. The small ones come on top. A small five-figure amount.
Still, even €500,000 is not enough.

in combination with the knee wall request 220

Right, there was something — namely the two-story structure, which is not allowed.

That's right, there was something – namely the two-story structure, which is not allowed.

I haven't read anything about that. You can't take the 1.5 from #1 seriously. If the general contractor plans a 2.20m knee wall, I assume there are 2 floors, as long as the original poster doesn't provide credible information.
