Floor plan optimization: Single-family house with 220m²

No, it was not ignored, I just couldn’t keep up with answering. For example, I come to the total using the Sparka construction cost calculator without land, but the topic of financing does not play a role for the floor plan at first.

However, it will play a role if you put together a floor plan that absolutely does not fit your budget. Just a note.

I take note, really. In that regard, however, we are well informed and do not approach the matter naively.

I wonder if noise is transmitted through the laundry chute and if it is therefore poorly placed in the bedroom? I imagine that sounds from the utility room can then be heard in the bedroom. Should the children then go through the bedroom to throw the laundry down?

Where is your building services installed?

Personal price limit for the house, including equipment:
€400,000, shell and interior construction will mostly be done by ourselves

Doing it yourself also costs money, namely the not to be underestimated material costs, tools, etc.

2. I’ve already racked my brains about this topic, can’t make the room look nice without changing the arrangement of the windows which would make it look less harmonious from the outside.

Oh yes... the windows are for the people WHO live IN the house and even though I understand that it shouldn't look completely odd from the outside, windows should always be placed according to the interior rooms!

5. Next to the WB there is a bidet planned, my wife insists on one

If it’s such a strong wish of your wife’s -> why don’t you have the bidet (plus the bathtub) in the master bathroom, but in the "children’s bathroom" or shared bathroom?! That just doesn’t make sense to me.

And the master bathroom is smaller than the guest toilet?!

- Laundry chute in the master bedroom leading to the utility room with washing machine/dryer.

Laundry chute in the master bathroom is only 1/3 of your laundry. And only the way down. And what about the kids’ clothes? And the clean laundry? Then you have to go around the corner through the kitchen into the dining room, along the whole staircase and upstairs?! Upper floor utility room or utility room entrance near the stairway would be possible solutions.

Further suggestions/criticism are welcome.

Upper floor looks tidier. Idea: remove master bathroom so that bedroom/dressing room can be a bit smaller, in favor of moving the bedroom/K1 wall downwards and the K2/K1 wall to the left = K2 becomes bigger.

Plus a window in the dressing room. But I think that was already mentioned once.

Apart from the electrical distributor, nothing else goes into the utility room.

I would now put a coat rack set in the niche which I think should be fully sufficient, I also find it quite practical that the toilet is right next door because there’s always someone who needs to go to the bathroom before leaving.

And the heating? possibly controlled residential ventilation?

Do the 4 children already exist or are they just planned?
Because it feels like the picture of the coat rack would not even be enough for me and my husband alone, let alone 4 (!) additional children.

In the utility room as drawn, we do without controlled residential ventilation, heat recovery, etc.

The bidet should go in the family bathroom because it is not needed in the parents' bathroom.
Is there a rule that the guest toilet must be smaller than other bathrooms?

The laundry chute in the parents' bathroom is only a third of your laundry. And just the way down. And the kids' clothes? And the clean laundry? You would have to go through the kitchen around the corner into the dining room, along the whole staircase and back up?! The upstairs utility room or a utility room entrance near the stairway would be possible solutions.

Why shouldn't one be able to transport three-thirds of the laundry through the chute?
I understand that the detour via the kitchen is not ideal, but we can live with it.

Because it feels like the image of the wardrobe would not even be enough just for me and my husband, let alone 4 (!) more children.

That was an example; I can well imagine simply building in a 2m bench with hooks for jackets, after all, one usually only puts on shoes and jackets there.
