Location of city villa or single-family house on 500 m2 plot - rectangular

As I wrote before, I am grateful for every opinion. I just have to keep in mind what it means if I decide for this or that. Critical opinions or warnings also help with that. At the same time, I am an adult and can decide for myself and also put the statements into context or perspective. I will actually ask what 50cm more in depth costs. That is another 5 m² more. The first 6 m² more had cost 6,500. If I extrapolate with the same rate, I would come to +5,500 (or +12,000 compared to the original offer). However, one would also have to weigh whether it would still be permissible based on the floor area. Interesting fact: 40m² / 5 = 8m² -> floor space requirement per person for offices according to occupational health and safety regulations. Which does not mean that I want to force my children to work.

I would not enlarge the whole house but extend the bay window in the dining room area and the children's room above it, as I also see more chances for an exemption if it gets tight with the floor area ratio.

Dining area

If I'm not mistaken, there is no dining area at all in the case of the L-shaped kitchen, right?

I wouldn’t enlarge the whole house but rather extend the neon bay window in the dining area and the children’s room above, since I see a better chance of an exemption there if the floor area ratio becomes tight.

Ok, I will take that up in the discussion with the architect as an alternative. Is such a bay window, which would also have to be deeper (2-3m?), cheaper than lowering the entire house by 0.5m?

There really isn’t a floor area ratio due to §34 anyway. I have to admit, I don’t know offhand whether there are many houses with bay windows in the neighborhood. The direct neighboring houses are rather very straightforward. Maybe I’ll take another look at it in the next few days.

If I’m not mistaken, there isn’t even a dining area in the case of the L-shaped kitchen, is there?

Well, it depends how you look at it. There is definitely a dining area, but you could say that kitchen and dining area are one since, due to the missing half-island, there is no real separation between kitchen and dining area. A bay window would of course create that separation again. But the bay window would have to be wide and deep enough. The 4m width from the children’s room is probably sufficient, but how deep does it have to be? And above all, then you really can’t walk through the dining area to get to the terrace when someone’s sitting there...

Here again as a reminder the custom design of the open plan living area with L-shaped kitchen:

Is it too tight? Factual? Where do you get this insight from?
Or would it be too tight for you?

Yes, I already said that. It would be too tight for me. That's what I mean by "own opinion." Or are you expecting a DIN standard for the space requirement of a family of five? (There probably is one.)

That’s the small but fine difference between objective and constructive criticism and purely subjective feeling.

I would claim that there was more constructive criticism from me in this thread than from you.
Sorry, but I do feel a bit offended when you discuss the pros and cons with the OP for days and then someone jumps in at the very end and tells you to please give constructive criticism instead of contributing your subjective opinion.

Anyway. I think the OP knows what I mean, and I also believe he knows that I am not trying to arrogantly criticize the lack of overall room size. The only debate here was whether to invest the money in more ceiling height or more square meters. I stick with the square meters.

I think the OP knows what I mean and I also believe he knows that I'm not trying to arrogantly bash the lack of spaciousness.

Yes, I do. I think we have now found our "modus discutandi"
I really appreciate your opinion and I will also oppose you if I feel offended.

Nevertheless, I am happy when other opinions come as well, so please everyone: No fighting!


Addendum:

Or do you expect a DIN standard for the space requirements of a family of five? (There surely is one.)

There actually is: just google:
"
Determination of residential space requirements according to VDI 6000 Part 1, DIN 18040-2
The appropriate floor area of an apartment or single-family house
"


There it says on a page for barrier-free construction:
Residential space requirements of a 5-person family:
126m² according to [IMG alt="Rollstuhlfahrer"]https://nullbarriere.de/images/wissenswert/Gesetze/rolli15.gif[/IMG]DIN 18040-2(R)*!!!

I’m building too big!!!

I would see the bay window here at about 125 (+/- 25) cm deep and as wide as the middle children's room. These 5 sqm will naturally be significantly more expensive than the normal square meters; even with - which I would recommend - a stepped roof (with a third gable the additional cost is out of the question). But as I said, in your self-planning variants I also do not see it demanded - just as little as adding additional square meters diffusely through more house depth to the total area. Don’t let yourself be unsettled: size is relative - "this much" of it close to the federal capital’s center will already make people in Stuttgart envious. And even in local comparison, you’ve hit the mark well - I recall from last year (and not yet really satisfactorily solved) a thread with a rear lot densification with a house-height-wise complex insertion by :
