House design

Why did the design turn out as it is now?
Standard design from the planner? Close adherence to production house (walls partly not moveable)
What makes it particularly good or bad in your eyes? very pragmatic/efficient, maximum area for living room, 3 equally sized children's rooms on upper floor. Maximum use of living space of the house with very restrictive development plan.

What is the most important/basic question about the floor plan summarized in 130 characters?
1. Are there any no-gos, things we might have overlooked?
2. How can we accommodate another office through modifications on the ground floor (upper floor)?
3. The hallway is quite small - problem?

Additionally: What is called "guest" on the ground floor is actually the office or the adults' bedroom. This was entered incorrectly. If it is the office, then the bedroom would have to be in the basement, which theoretically is no problem thanks to the underfloor heating. But the basement has only one light well per room. So hardly any light. -> This is our main problem with the floor plan. Thank you for your trained eye over the floor plan. The planning of the final floor plan should be completed by mid-March.

Where is the driveway??

Number of people, ages: 2 adults, 3 children

Office: home office

Overnight guests per year: once

What do you like especially? Why? Large children's rooms

3 children, 2 children's rooms, ... maybe you could write something about that? That probably doesn't make sense to anyone. Also the ages of the children please, if one doesn't get a room at all.

Where is the driveway?? 3 children, 2 children's rooms, ... maybe you could write something about it? Probably no one understands that. Also please include the age of the children if one of them doesn't get a room.

But there are 3 rooms upstairs. The parents' bedroom and office are supposed to be on the ground floor and in the basement.

3 children, 2 children's rooms

Thanks for asking. I had forgotten to write that instead of "Sleeping" above, it should actually say "Child 3." Great that you are paying such close attention!

Roof shape: gable roof 45 degrees, about 1.30 m knee wall

This combination results in a tower-high roof.

Standard design from the planner? Close adherence to a type house (walls partly not movable) What do you think makes it particularly good or bad? very pragmatic/efficient, maximum space for the living room, 3 equally sized children's rooms on the upper floor. [...] 1. Are there any no-gos included, things we might possibly have overlooked?

In my opinion, the no-go consists in the lackluster planning - was the conversation like that as well, i.e. did you signal too little serious interest? (if you have nothing to "blame" yourselves for in this regard, I would send the provider packing).
