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

I'll take a look at the construction performance description...

So, that's all I found:

The ceiling on the ground floor is constructed in reinforced concrete (filigree ceiling with steel and concrete C25/30) according to the structural analysis and the ceiling joints are sealed and puttied (Q2). [...] A floor heating system with insulation is installed completely on the ground and upper floors. [...] All rooms on the ground and upper floors receive a floating screed (cement screed d=65-75 mm) including thermal and impact sound insulation according to the applicable thermal insulation and soundproofing regulations with perimeter edge insulation strips to avoid sound transmission and PE foil. Thermal conductivity class and insulation thickness result from the requirements of the Energy Saving Ordinance and the thermal insulation verification. In the case of barrier-free showers, the screed must be omitted and adjusted by the tiler (slope alignment).

I wanted to put tiles on the ground floor and vinyl on the upper floor. So unfortunately no very concrete details. However, as mentioned, in conversation we arrived at 2.5-2.55 m clear room height. Specifically, he calculated a floor construction of 20-25 cm on the ground floor. On the upper floor about 10 cm less, because insulation to the base slab is missing/unnecessary there).

The story height is, as far as I know (please correct me if I’m wrong), the height from the top edge of the base slab to the top edge of the ceiling.

Wow, that would be intense. I hadn’t understood it that way and the site manager hadn’t explained it that way when I specifically asked about the clear room height on the ground floor with a shell construction height of 2.75. I mean, the intermediate ceiling also sits on the outer walls, which in turn stand on the base slab. From my layperson’s thinking, it wouldn’t be logical to measure that height up to the top edge of the intermediate ceiling even with the shell construction height. Of course, for the staircase height, the upper edge of the finished intermediate ceiling plus floor covering must be taken into account. I will follow up on that, but maybe someone here can say something about what is generally usual? Because I wouldn’t want less than 2.50 m (+/- 2.5 cm) clear height on the ground floor. Best regards Tolentino

Asked for a raw construction height of 2.75.

Raw construction height is something different from story height.

There is story height:
The height from the raw floor of one story to the raw floor of the story above is referred to as story height. Story height thus includes the complete height of a floor including the entire ceiling height and floor structure.

Raw construction height and clear room height:
A distinction must be made between clear room height and raw construction height, which is defined as the distance between the top edge of the raw floor and the bottom edge of the raw ceiling – that is, without the floor structure and ceiling plaster. The final clear room height results after subtracting the height of the floor structure and the ceiling plaster.

And a staircase must always overcome the story height.

: Thank you very much for the clear explanation and the picture. Ok. So we never talked with the site manager about the story height. In my opinion, it was about the difference between the clear shell construction height and the finished room height. He stated 20-25cm here (floor construction in the ground floor). Is that realistic?

For people over 180 cm tall, walking down the stairs is uncomfortable.

Even without experience of bumping one's head, when seeing the edge approach (unconsciously, and thus the ideal beginning of a chronic ailment) one will duck the head. For the same reason, I generally advise against designing houses in such a way at certain spots that it just barely works out mathematically. By the way, Kerstin also reminded me at the spot I linked a few hours ago that a walking person is in motion, which gives their height a dynamic quality. A head height DIN of 2m therefore still has the 1.80m man in mind (which still often fits my generation, but only rarely those of the sons). The seemingly identical 2m of stair walking are thus not quite the same as when standing up from the toilet, which one rarely does in a vigorous jump.

Yes, I think so too. We are all root gnomes here, two fingers over 1.7m, but you also have guests sometimes and I didn’t want to put a yellow-black warning stripe on the edge. However, if kaho’s calculation is correct, then even 2.10m should be possible. And I think no one is that dynamic when climbing stairs. It is definitely important to pass this on to the site manager for the architect. By the way, did you actually reply the other day? I got an email but then couldn’t find the post...

Say, did you actually reply the other day? I received an email but then couldn't find the post...

Do you mean: You got an email notification that I had written a post, but it was a false alarm? - I think I deleted a post of mine immediately last week (but to my memory not in one of your threads) because my previous one was still within the editing time and I didn't need to start a new one, but could still add the supplement.
