The dining area is too tight.
A minimum of 80 cm (31.5 inches) between the table edge and the wall is recommended. For the kitchen unit, I would plan at least 1.20 m (47 inches) from the table edge. There should be enough space for someone to walk past even when the area is occupied.

Thanks, I’ll think about it some more.

Are you referring to where the refrigerator should go? Or are you making a schedule for when the dishwasher will be opened so others don’t bump into it? I would already find that challenging with two people, but with three children, no way.

Everything should go into the large garage ;-)

Are you supposed to keep going back and forth to the garage constantly? In my 5-hour afternoon shift, I’m in the utility room and storage room about 10 times a day... and I don’t even have three kids. Is the garage heated? Many things need to be stored inside the house. Laundry in the garage? What you’re planning is unrealistic and, sorry, out of touch with reality. Having an office in the hallway between the kids’ bedrooms was also mentioned... The house just won’t work.

Oh, stairs: if the 20 refers to the height, then the staircase will be steeper than the standard of 19. One centimeter (0.4 inches) may seem small, but for some people, it can make the stairs a bit more tiring to climb.

The "Inspiration" has nothing to do with Bauhaus either.
Storing everything in the garage, as @ypg already mentioned, is not really practical.
Especially since the garage is not that large. With three children, there are also bicycles and other items to consider.

I can only agree. The staircase would be way too steep for me, there is very little space around the dining table, and an open office is not an option for me (working from home for the last 3 months).

I would also miss storage space. Besides many everyday items, hobbies also require room.

The office will move to one of the children’s bedrooms in the medium term; our eldest is already 21.

I am considering adding a door from the utility room to the garage and possibly enlarging the garage further.
The overall size of the house must not increase any further, firstly for cost reasons and secondly because the building coverage ratio of the neighboring buildings must be adhered to.
