Single-family house with gable roof, without basement - Feedback desired

Have you ever drawn the desired furniture to scale in the floor plan?

Where is the wardrobe for 5 to 6 people?
I don’t see any space for shoes, jackets, and bags.

What is the utility room intended for? You wrote building services, laundry room under the roof.

Kitchen: I don’t want the door to the garage. Fire doors are either expensive and/or ugly.
I would have left out the kitchen/utility room corner and rather planned a proper pantry.

Do you really want such small and floor-to-ceiling windows?

Dressing room window opposite the door.

Bathroom: no bathtub
Only 1 sink?

What does the attic look like?

I am also missing furnishing sketches. Windows and doors are also noticeably often planned in the room corners.

Hello,

the utility room is too small, you lack storage space.
Getting from the garage to the kitchen is also not ideal, you bring garage air and dirt into the room where you want to prepare food.
In general, I would advise against entering the house through the garage; that would be too insecure for me. You will probably also have to install a T30 door, which are functional doors, and I don’t know if they come in nice designs.
Are you planning the roof as a cold roof or will it already be insulated? A cold roof is not necessarily good for the building services either.
You might face some structural challenges, as the ceiling would have to bear quite a load
(we also have three children and a 300 l water tank, but on the ground floor).
Do you really want to walk so far to do laundry?
With three children, there is a lot of laundry.

The utility room downstairs is intended for the house connections and is also used as a wardrobe. We want to keep the door in the kitchen and set up a storage room in this space. We will separate the room from the garage. The bathtub is planned immediately to the left behind the door in the bathroom. We are not yet completely satisfied with the windows.

Well then...

First of all: furnish the floor plan. To scale. That should be interesting in the kitchen and living area on the ground floor. Presumably, the kitchen is not so easy to furnish in terms of distances.

What is the utility room (HAR) intended for if the heating is to be installed in the attic? Could the recess in the kitchen possibly be omitted?

Where should the wardrobe for 5, possibly 6 people go?
What do you expect from the door from the garage to the kitchen? I imagine it as quite a dirt trap, and then you first have to go through the dining area with dirty shoes to get rid of them and the jackets.

Should there be an additional bathroom in the attic? With 6 people, I would rather do without the dressing room and instead plan a children's bathroom.

Child 3 is noticeably smaller than the other rooms, especially since the entrance area is actually non-existent – you really can’t place anything useful there. It would be noticeable if you had already drawn in furniture. Likewise, in the dressing room, there isn’t as much closet space due to the unfavorable window position – or is that meant to be a terrace door to a roof terrace?

I find the sizes of the children’s rooms too unbalanced. A corridor width of approx. 1.1 m is very narrow.

Why do you want to separate the toilet in that way? Also furnish the bathroom. It seems large, but where do the bathtub and a double washbasin AND additionally a cabinet or shelf for the stuff of 5-6 people have space (in case you decide against a second bathroom)?
How is the drainage supposed to work?

Just saw that there is supposed to be a partition between [Essen] and [Kochen]. That leaves about 3.2 m for the dining table, if I have deciphered it correctly? I think that is clearly too little space; if a 1-meter-wide table is fully occupied, it is almost impossible to walk behind the chairs.
