Floor plan change single-family house 150 m² due to stairs

said it all. Ordered floor plan with few "errors" that can be corrected. (Even if it wouldn't be "my" house) I would also criticize the narrow wardrobe door: 60cm is too narrow for a pantry or wardrobe, meaning a utility room where bags or bulky items (sports bag) might be stored. A normal room door has the advantage that Manu can use the room secondarily. Here you would have to pass things to each other one after another. Or you might break the wardrobe doors with bulky items. I find the fireplace a bit lost. Besides, the door will be in front of it. The chimney is missing on the upper floor. I also find the dressing room access unsuccessful. Note: the 3D program or images are distorted and do not represent the human viewpoint.

Thank you for your opinions.

What I would change:
- Leave the stairs to the basement open, it gives more spaciousness to the hallway and the descent doesn't become such a dark hole.

I actually wanted to leave it open..... but my wife is "afraid" of the basement :)
And the entrance area we have from a show home, I don't think it's that dark, right.... Here is a picture of the entrance area

- Skip the pantry because you have a basement where you can store a lot. Climbing stairs prolongs life! ;)

Yes, that's exactly what we're thinking too but a pantry on the ground floor has something. We will have to discuss with the kitchen planner anyway whether the pantry can be used well without making the dining area and kitchen too tight. Otherwise, the pantry will be dropped.

Kitchen instead of 400 cm better 425 wide, then you get 7 tall cabinets of 60 cm side by side. That gives storage space without end.

I'll redraw it and try it out this weekend :)

The stairs then shift 25 cm to the left, bathroom becomes a bit smaller (110 cm for shower and toilet is enough). Also the bedroom becomes 25 cm smaller, but you have plenty of space there. The children's rooms gain the 25 cm.

Upstairs I also think the 25 cm would be manageable. If we shift 25 cm over, I only fear that the entrance area with the wardrobe will become too tight....

Is the wardrobe room supposed to be accessed through the closet?
Do you have exterior views? There are still some windows missing, e.g. in the bathroom and the child's room.

Entrance through the closet was an idea of mine. :)
Yes, windows are still missing, I'm always too lazy to draw them in :)

I would also criticize the narrow wardrobe door: 60cm is too narrow for a pantry or wardrobe, that is, a utility room where bags or bulky items (sports bag) are sometimes placed.

I would have thought more of 80-85 cm here.

I find the fireplace a bit lost.

Where else :) Yes, I forgot the chimney, sorry.

Yes, that’s extreme, a 90cm door looks like a 65cm one :)

Yes, that's exactly what we're thinking too, but a pantry on the ground floor has its advantages. We will have to discuss with the kitchen planner anyway whether the pantry can be used so well without making the dining area and kitchen too cramped. Otherwise, the pantry will be dropped.

Don't forget that this also affects the position of the windows! By the way, I live without a pantry but with a basement. However, I have a large kitchen with plenty of storage space.

Upstairs, I also think the 25cm would be manageable. If we shift 25 cm over, I am just afraid that the entrance area with the wardrobe will become too tight...

The WC and wardrobe can become narrower, and the front door and entrance area will also shift 25 cm over.

I actually wanted to leave it open..... but my wife is "afraid" of the basement

If I had to step into such a dark corridor, I would be afraid too :p

And we got the entrance area from a show home, I don’t think it’s that dark or.... Here’s a picture of the entrance area

…and if I tell you here that this hallway has been professionally fully lit from inside and outside by photographers and lighting technicians in order to advertise effectively? I can recognize that as a photographer. They even placed lights outside, suggesting sunlight in front of the entrance door. There is hardly any shadow casting, and if there is, it is illuminated. Take a look at your visualization: where is natural light supposed to come from? Opposite the door without a window is a solid wall. Your stairs are closed underneath, the room doors do not light the vestibule..
Your hallway and the pictured one are not the same, yours will be much, much darker.
You withheld the orientation from us: where would south be?

Yes, that’s exactly what we’re thinking too, but a pantry on the ground floor has its perks.

But not such a windowless tube ;)

This is the model house of Schwörerhaus which has been presented on YouTube by Hausbauhelden. There is enough light in the entrance area without any fakes.
