At the request of 11ant, here is a post with the completed list ;-) Unfortunately, he still doesn’t have a crystal ball.
Providing all information possible/available at this point in time.

Development Plan / Restrictions

Plot size: 400 sqm (4300 sq ft)
Slope: No, and no means no!
Floor space index (FSI): 0.4
Floor area ratio (FAR): ?
Building envelope, building line and boundary: Yes, available.
Edge development: Possible with garage.
Number of parking spaces: at least 1, preferably 2
Number of storeys: 1-2
Roof type: Gable roof (pitch minimum 31°, maximum 45°)
Architectural style: ??
Orientation: Gable end facing
Maximum heights / limits: Roof ridge 6-7 m (20-23 ft), eaves 9-12 m (30-39 ft)
Other requirements: No brick facades allowed. Driveway or space in front of garage at least 6 m (20 ft). Red roof tiles mandatory, light facade.

Homeowners’ Requirements
Architectural style, roof type, building type: Gable roof, fixed
Basement, storeys: 2 full storeys without basement
Number of occupants, age: 4 people (2 toddlers)
Space requirements on ground floor and upper floor:
Office: Family use or home office? Office of approx. 12 sqm (130 sq ft) is a must.
Guest bedrooms per year: Few
Open or closed architecture: ? Whatever that means.
Conservative or modern construction style: rather modern construction.
Open kitchen, cooking island: Open kitchen, possibly with cooking island
Number of dining seats: 6
Fireplace: NO
Music / stereo wall: Not planned, TV location is quite important.
Balcony, roof terrace: NO
Garage, carport: Garage desired. Carport with storage box also conceivable.
Utility garden, greenhouse: NO
Further wishes / special features / daily routine, preferably with reasons for choices:
Laundry room on the upper floor. They want to do laundry where it is generated and where it must be returned clean. Anything else is a hassle, at least for us.

House Design
Who designed the plan: Architect

What do you particularly like? Why?
Everything we provided as basic information and what our daily life requires has been implemented.
We like the clear lines/structure.
The open space in the hallway.
The connection/proximity of all rooms on ground and upper floors that need water/sewage. So no funny business with the bathroom upstairs in one corner and the utility room diagonally opposite on the ground floor. Personally, I like that.
No bay windows or other awkward extensions.
Laundry room upstairs where the washer and dryer are planned.

What don’t you like? Why?
The living room might be a bit too exposed for us. It could also be a cozy nook with TV without direct view of the kitchen. Cooking and eating together openly is liked; the living room could be a bit more separate. Currently, the floor plan shows it like a narrow, rather shadowy corner.
The somewhat narrow bedroom upstairs is not a dealbreaker but not 100% pleasing.

Price estimate according to architect/planner:
-
Personal price limit for the house, including fixtures and fittings:
500-575k
Preferred heating system:
Predefined, ground source heat pump with collector. Cold local heating network.

If you have to give up, which details/extras
-can you do without:
The small additional room for the father upstairs.
Garage, as mentioned carport also conceivable.

-can you not do without:
Office.
Storage box at garage or carport.
Children’s rooms.

Why is the design the way it is now? e.g.
The design turned out this way because the architect implemented our wishes and requirements almost 1:1. This preliminary layout resulted in this first version.

What do you consider particularly good or bad?
See what we like and what not. We don’t find anything particularly bad. Rather, not entirely optimal.

What is the most important/basic question about the floor plan in 130 characters?

Position garage flush with house or set back?

43.5 sqm (468 sq ft) + 4 sqm (43 sq ft) pantry sufficient as “all-purpose room”?

Same floor plan possibly mirrored? Then office on south side, sun all day, blinds always down. Same issue upstairs with bedroom in summer at least. Entrance farther from parking space.

The building method will be timber frame construction with a local timber builder.

This is a first sketch after clarifying needs/wishes with the architect.

Does the "hobby room" serve as an additional space for both children's rooms for crafts, building Lego, etc.? If so, the size of the children's rooms is appropriate. Otherwise, I would omit the hobby room and add that space to the children's rooms.

Here is my idea.
With a different staircase, that is, a landing redesigned in some way, it wasn’t quite satisfactory for me. The fact is: long staircases create a lot of hallway space. I find hallways a waste of space, but it’s not my house.

Thanks for that.
Regarding the open-plan living area and office, I think it’s very good. The rest of the ground floor at least offers a solution.

Unfortunately, the upper floor doesn’t really suit us. Almost twice the space taken up by the hallway upstairs. Hmm.
Also, we would prefer the children’s rooms to face the garden. The bathroom size is fine and would work for us.
By the way, sometimes dad also does the laundry here. 😉 😀

The hobby room is basically not really a must-have. You could do without it if necessary.

It’s deceptive. I’m not sure if the software includes the staircase in the calculation, but in your case, it’s the void space that you can count as wasted hallway area, just like the oversized bedroom. In my design, you come upstairs and are greeted by windows and natural daylight.
As I said before: a long staircase results in large hallways.

In my case, they deliberately face south to maximize brightness. The bedroom deliberately takes the leftover space – I have already explained this in writing at some point.

That was also a running joke on

The small extra room for Dad on the upper floor.

I checked again: the stairwell opening is not being deducted in my plans. I wanted to make some more changes, including to the upper floor, but the staircase is simply an obstacle when it comes to door placements on the upper floor…

Here is another idea for the upper floor with the disadvantage that the children's bedrooms cannot have the wardrobes placed behind the doors.
