Thank you for the many responses!
I always find narrow, hose-like entrances terrible. Imagine 3 people want to go in and 2 out, maybe visitors in between. Horrible. A lot of space is lost for the hallway, which then isn’t even spacious.
Otherwise, the hallway downstairs would be too narrow, too long, and too dark for me.
The narrow, long entrance is not my favorite, but the best/only solution if we want the entrance on the side (and that is more important to us). Otherwise, we would have to cover a long, narrow part on the front side of the house, which also looks bad...
The utility room is very small. What exactly should go in there? We also have geothermal heating. The device alone takes about 1.50m². Then there is electricity, water, and for you also a washing machine and pantry. Good luck!
The utility room could be bigger in my opinion, but how? Regarding the heating: you built in 2013/14, if I see that correctly. The devices nowadays supposedly only need 1m².
I would make the children's rooms upstairs bigger and the hallway, bathroom, and master bedroom smaller.
How? Turn the stairs around and then make the hallway only as wide as the stairs? The bedroom can’t get much smaller due to the closet, and the bathroom not much smaller because of the stairs either.
I find the passage behind the bed a bit tight. A mattress is already 2m long, plus the headboard and bed frame, and the bed is not right against the wall, so you quickly need about 2.20m of space. The masons don’t build exactly to the centimeter, and you have to plan for 3cm of plaster. So you only have about 56cm of space behind the bed, which is quite tight. You will surely bump into the bed or wall more often. Otherwise, the hallway downstairs would be too narrow, too long, and too dark for me.
The bedroom feels cramped – I hope you can get in the mood there. I would be frustrated because I’d constantly have to stare at the oppressive wall way too close in front of me.
We actually see the bedroom the way does, it doesn’t have to be big:
You only walk through the bedroom twice a day, I think that’s completely fine. There’s no closet or anything you have to get to. I think it’s nicely solved.
Hmm ... if the area is to be furnished as currently planned, then although it’s open, with the fireplace, etc., it’s unfortunately no longer spacious.
Home office, if seriously done from home and with 3 kids around, actually shouldn’t be in the family room. Playing children, running kitchen appliances, and the like don’t go well with phone calls/conferences, etc.
Stairs ... you plan a space of 177x210 cm, that will be cramped and quite steep, I even claim it will be impossible. Take a look at such stairs in person. In the “First Reading” post in this forum section, there is also a stair overview that recommends about 230x230 cm for this type of stairs if the stairs are to be comfortable and if you also want to transport something larger there. And with that, the room plan would fail.
How would you otherwise furnish the living room?
The children will just have to play in their own rooms until everyone is done working. Or if it really doesn’t work, one can retreat to the guest room where a home office workspace could be set up. I don’t see it as a problem; it works quite well for us at the moment (we are just doing exactly that).
Regarding the stairs, I have to say we never really thought of that and just trusted the planner. The room height is also "only" 2.40m (same as now). I was always a fan of large, cozy stairs. But ideally, you only move 1-2 times, so I don’t want to sacrifice living space for that. But we really should check it out in real life.
