House design
Who created the design:
- Planner from a construction company: yes
- Architect: yes
What do you particularly like? It is already quite planned according to our ideas, but could be improved
What do you dislike? staircase, arrangement of bathroom upstairs
Preferred heating technology: still undecided air-water heat pump or gas (but needs balancing area for energy saving ordinance, right?); geothermal not allowed

Please provide improvement/optimization suggestions. Especially regarding the staircase I would like to hear your opinions. We probably would not leave the roof window above the dressing room but arrange it above the stairs, opinions?

Edit: The house will have about 152m² living space

The architect seems to be a fan of walk-through rooms...

That the office (and later, when fully occupied, i.e., with 2 children, probably also the guest room) can only be accessed through the living room I find, to put it politely, rather suboptimal...

If grandma should visit later and goes to bed earlier than you and then maybe needs to use the potty again, she walks across your living space in her nightgown. For those who like that...
Even if the room is only used as an office, the distances here would be too long for me. Suppose I am sitting in the office working and then the mail arrives and rings the doorbell. Well, we have already had a design here that contained a sophisticated fitness program in terms of layout. But I don't consider that well planned...

Furthermore, the hallway would be a bit too small and too twisted for me. With two children only that little bit of closet? What if you as a family come home together, maybe one child still in the stroller? How is that supposed to work?
I don't see any space for a stroller here at all. Can it stand in front of the door? Do you want that?

And upstairs: why can the storage room only be accessed from the bathroom? Was that your wish? Otherwise, I would put the door here from the hallway.
I also don't find the bathroom layout optimal, but that can be changed quickly:
Bathtub in the lower right corner in a N/S orientation, not E/W as it is now, window more in the middle (is that possible from the outside?), shower then where the toilet is now, then you can move the back wall a bit closer to the door, which creates a small niche opposite the door where a small cabinet fits perfectly, and the toilet on the north wall under the slope. Whoever wants can still put a partition wall between the tub and the toilet.
Why no light in the dressing room? I would keep it.

However, I see significantly more potential for improvement on the ground floor (although I don't have a brilliant idea off the top of my head).

And OG: why can the storage room only be accessed from the bathroom? Was that your wish? Otherwise, I would make the door from the hallway.

The washing machine and dryer are in there anyway. I find it practical that way, we have it too.

No door to the living room?

Otherwise, I see a bit too many corners ...

Oh, those are the washing machine and dryer; I didn't recognize them like that. To me, it was a room for cleaning supplies, vacuum cleaner, etc. I personally don't find it practical to have the washing machine and dryer in a separate room without a sink next to it and also windowless (it gets so hot with the dryer), but that's certainly one of those things where some see it one way, and others another.

I also like the room on the upper floor for laundry.

What I don't like about the floor plan:
- Children's room definitely too small in relation (>24 sqm for master bedroom, 13 for children -> does not fit at all)
- Staircase right at the entrance always has the dirt problem, that's not for me, a few meters between staircase and door would be enough to have a small dirty zone to take off shoes, but as it is, you have nothing. Especially with children, it's annoying.
- Walk-in closet rather impractical, but it could certainly be changed fairly easily
- Dining/living/kitchen area is perhaps a bit outdated (modern would probably be kitchen and dining room together and the living area separated), but if that's what is wanted, of course OK
- Comment already came: Feels like too many corners

Hi,

thanks for the tips and criticism. That's why I opened the topic

- The office/guest room only has the door through the living room because of the stairs. I think the stairs need to be arranged differently, any tips?
- I also don't see space for a stroller yet
- Well spotted - the washing machine will go upstairs and the controlled residential ventilation is planned there.
The dryer is not certain yet, at the moment we manage without one
- A door in the living room is currently not planned, to be honest I haven't thought about it at all
- I just don't know how to take away something from the bedroom and credit it to the children's room. We don't need a large bedroom, as we mostly just sleep there
- I wanted the kitchen to be separable from the living-dining area with a sliding door when needed

In the utility room you can also see the chimney flue, the masonry heater is supposed to go in the corner of the living room. Unfortunately it's not drawn in.
