Penthouse floor plan - Is it that practical?

Hello ,

thank you very much for your assessment.
Regarding the entrance area - good point! I don't think it's that bad, but you're right, it's not really solved happily. Maybe the door can be shifted a bit to the left if we make the WC smaller. Smaller because I think we only use the shower downstairs about 3 times a year and for that, on the one hand, it's quite an expensive pleasure and on the other hand, you constantly have to remember to run the water - Legionella issue?
So smaller WC, thus the entrance door further to the left. But that also means more square meters for the hallway.
Pushing it together in width is a tricky thing. The living area is planned so that our current U-shaped sofa fits in and the surround speakers still find space in the back left and right.
The dining area should stay that big because otherwise it will be too tight at Christmas, birthdays, etc.
The kitchen: there is actually still a (cooking) island planned. If we leave that out and reconsider how much space we actually need in the kitchen, we might be able to cut about half a meter here.
But for this half meter, I find at most some leeway in the office on the other side. Because if I make the utility room smaller (which actually does need space due to smart home), the staircase shifts and then I'll have the chimney standing in the middle of the room upstairs afterwards.

I have now first shrunk the upper floor by about 10 m².

I have removed the rear offset. Unfortunately, the huge wardrobe no longer fits because of that, but instead there is a quasi walk-in wardrobe behind the bed. The nightstands had to give way for that, but there's currently only a phone on them anyway.
Additionally, I have taken half a meter from the children's rooms and moved the wall to the bedroom slightly to the right in children's room 2.

Regarding the bathroom: of course the "T" takes up space, but because of the stairs we have to extend the bathroom anyway (in width), and the length is also reduced to a minimum (the door has to go somewhere). Extending the outer wall further toward the stairs probably makes little sense cost-wise, because then the statics would require increased demands on the intermediate ceiling, right? (because then the upper floor no longer rests on the lower outer wall)

2.85m raw construction width in the bedroom? And then with "space" behind the bed. Who is supposed to squeeze in there?

Ground floor, entrance:

There are easily 2-3 meters of cabinet space missing for jackets, shoes, bags, umbrellas, hats, keys & co....

True. Maybe rotate the bed again and move it quite close to the door. Then move the partition wall upwards so that a larger passage to the dressing area is created at the bottom?

Jackets are supposed to hang on the back wall of the WC. A large wardrobe fits opposite the entrance door and a wardrobe should also be integrated into the stairs. Winter jackets can be stored elsewhere in summer. Don’t you think that’s enough?

Otherwise, is everything perfect?

Topic ceiling height. I would now assume a clear height of 2.60 m.
But I thought about lowering the ceilings everywhere by 20 cm to be flexible in the future. So basically a clear room height of 2.80 m from the builder, and when he is finished, I will come by and lower the ceiling everywhere so that in the end there is a clear room height of 2.60 m. Or might that possibly feel oppressive in the large dining/living area?

Food for thought for the kitchen: With so much dance floor space, extra deep countertops and cabinets (>=80cm) are recommended. The island trend will fade - space for working, even if the toaster is on it, remains.
