Floor plan spacious house, barrier-free

Well... plans should always be set up according to how the furnishing is intended. And, having the bed with the headboard on the right-side wall is even worse, since one head always lies in the passage area to the wellness room.

And honestly, sayings like

Unnötig groß = Ansichtssache

I just find totally stupid if it’s not explained what one thought with their arrangement... sorry if I'm this direct, but your information regarding your project is designed in a way that you won’t accept any other answers anyway and are just "fishing for approval."

It is not barrier-free, but also not strictly required. If barrier-free becomes necessary in a few years, then the necessary adjustments, such as a stair lift, should be feasible without major effort.

You have assigned a position for the stair lift, but if it is in use, the passage from the hallway to the living area... well, I would say, no longer barrier-free.
And installations like the bathroom, etc., should at least be designed with the idea (main topic)

Generous house, low barrier

at least at the area level to be low-barrier and barrier-free in concept.

3 cars and the airspace simply results from the roof shape.

3 cars for 2 people, why is that? And a recognizable site plan with street access, garden area, or similar? By the way: Does the floor area ratio actually allow for so much built-up property? Just the house and garage are almost 250 sqm out of 660, plus terrace, access path, etc.

I don’t need and don’t want approval. Everyone can think it’s nonsense.

Do you have to justify yourself nowadays if you have more than one car? Does it calm you that 2 of them are electric? By the way, everything is approved as is...

Yes, so what is your goal now with this floor plan discussion? You have shortened the linked list of questions from this forum section by removing everything that helps to understand a plan and the people behind it.

And no, basically no one has to justify themselves, but anyone who publicly puts themselves up for discussion must also be able to take questions, and if you really want to gain something for yourself, you must also answer questions, including questions about missing information. And not just with selected points.

I find the kitchen extremely impractical and ugly. Is there already a plan for it?

The upper floor is, in my opinion, a disaster. Unnecessary walk-through rooms drive you crazy.

The desire for so much space in old age is rather unusual. At that level, however, I would at least expect the room for the housekeeper / caregiver as an option.

If the elevator is necessary, the house has narrow spots. The bathroom upstairs only works if you have two healthy legs and need no assistance.

Entry hall ground floor, WC, wardrobe do not fit with the elevator - and limited mobility.

Since money is probably available - I would plan a room with a small bathroom for a caregiver/household help. Age, illnesses may make this necessary.

The floor plan is not mine. The kitchen is kept slim, the passage to the pantry is narrow, beside the sofa you can hear the heat pump.
The bedroom feels like a loveless ballroom equipped with a bed and wardrobe.

What is supposed to go in the wellness room? No access to a terrace desired?

It can be smaller and better.
