The floor plan gives me the impression that the planner from the construction company tried to somehow fit in every single wish. In my opinion, it doesn’t make the home feel cozy.
It starts with the hallway. For me, the hallway is actually the business card of the house, but here it is unfortunately a dark and cramped place. When several guests arrive, they first have to be led one by one through the kitchen before everyone can be greeted. There is also no space for shoes here. The workaround is to store shoes in the carport in the future. Is that seriously going to be the shortcut for the rest of your life? What do you do when you have birthday parties? Make all the guests leave their shoes in the carport? Do you have slippers for everyone there, or do they have to walk back into the house on their socks through the dirt without shoes? I imagine that looks quite funny in snowy winter weather. The carport is probably not locked either and accessible to everyone (people and animals) at any time of day or night?
Next is the utility room. 6 sqm for heating, electrical, water, washing machine? That will be very tight, and in the end, due to lack of space, the washing machine will end up in the kitchen.
It gets tight with the stairs. We have 19 steps and 3.2m x 2.2m to comfortably reach the upper floor. I would like to see the planning of your stairs from the staircase builder.
On the upper floor, there was a forced attempt to cram in three children's rooms at all costs. I wouldn’t want to grow up in "Child 1." Due to the close proximity to the parents’ bed and the small room, you experience every lovemaking session of the parents up close. Additional frustration arises when the demands on the room increase with age. Try furnishing the room sensibly for a >= 12-year-old (desk with PC, TV, wardrobe, 1.60m bed).
Because of the three children’s rooms, the master bedroom is very cramped too. The spouse who is forced to sleep at the end of the bed is not to be envied. With a raw room width of 2.80m, there will be at most a passage of about 54 cm left (280 cm - 6 cm plaster - 220 cm bed). Probably even less. After the person has broken their toe on the bedpost for the second time, it would be kind to switch sides occasionally.
My tip: As some have already written, best start again from scratch and consider whether you might want to invest a little more money and enlarge the house a bit. With 10x10m, accommodation wishes such as a third children’s room or guest room on the ground floor are difficult to implement sensibly without impairing other rooms.
