I like that better. Of course, it needs some revision. I wouldn't place the sofa like that. I would also leave out the door to the living room... However, I would position the air space where it actually catches something [emoji2]

Do you think it's better to walk through the kitchen into the living room?

In the attached image, the air space is by the window. Unfortunately, I cannot display that from the software.

I can also manage with 2D [emoji846]

I wouldn’t make the airspace in line with the stairs. CH would possibly revise the upper floor and move the bathroom somewhere else. You don’t want a kids’ bathroom anyway, or did I misunderstand that?

I wouldn’t have a problem going into the living room over the kitchen, but that could also interfere when surprising with sweet treats. However, I don’t consider it a problem: the kids should all stay in their rooms on Christmas Eve until the bell rings.

Due to the missing thermal break element, I have decided to cancel the originally planned bay window.

Technically, this is absolutely sensible. Nevertheless, it also has the consequence that additional cubic meters of the overall structure now extend into the living space (and thus become somewhat more expensive than if they had remained open air above terrace slabs). You seem to be quite generous with the sliding lift-and-slide doors, and your modified stair sculpture is still far from a model for those with statutory health insurance. So I see good reasons to share the doubts about budget compliance. From my point of view, it remains that the budget increases to implement this plan will exceed the value of the floor slab torso – by my current estimate: by multiples! – This will be a Pyrrhic victory of nearly royal Bavarian proportions. Apart from the sensibility of such an undertaking: do you still have your financier on board, or are you now sailing alone with your draftsman friend and a bag of gummy bears? It seems to me that the time has come for you to weigh two alternatives: Path A) Planning a needs-based home for your family, significantly more affordable by “giving up” the integration of “gifted” unnecessary square meters, but with considerably more living value through a smarter layout. And with an event that no one from your circle of friends will top: namely a solemn Hilti burial of the floor slab, where other builders would only be able to offer a meager cornerstone ceremony. Path B) Selling the property, after the only pleasure of having discussed house plans with us. No matter how you look at it: sticking with this floor slab forces upon you, in my view, a house about one third too large – and even then, the extra size would not increase or at least be neutral for living quality. You will have to finish building the house of your predecessor and then hand it over to the next buyer, because unfortunately it has also become too expensive. One should not look a gift horse in the mouth – but on the other hand: if it’s dead, you shouldn’t ride it anymore.

I tried something again... please don't orient yourself to the wall thicknesses, with the program these 10cm are always preset

.

Edit: the bathroom has no window, I just noticed... then it has to be swapped again... this is about the stairs and the open space here

Here is the upper floor... Children's rooms are each 18 sqm, the air space is approximately 4 x 4 and is also marked on the ground floor.

Windows can be arranged on the ground floor and upper floor.
I have dedicated an entire wing to the parents.
