Our floor plan - suggestions for improvement?

Hello,
at first glance, four remarks:

[*]I would leave out the pantry. Allocate the space to the utility room (you will need it there) and rather put a storage shelf there. In the kitchen, you can probably fit two tall cabinets, in which you can store almost more than in your 40cm narrow shelves in your pantry.
[*]I miss a proper coat rack (60cm depth).
[*]I don’t like it when the doors have different widths (88cm and 76cm). Our architect also planned a 76cm door in our guest toilet, which we enlarged to 88cm. Often people don’t think about it, hence the note.
[*]In my opinion, your bathroom is too narrow for a good T-solution. Search here in the forum for the L-solution for the bathroom (that’s what we have).

Will there be a sliding door between the hallway and dining area, or will it remain open?

You can put the coat rack in the hallway, right, or what do you mean?

I think if we install a bigger door in the guest toilet, it will get quite tight in terms of space, since it’s already so small, isn’t it?

I’ll have to look for this L-solution.

The hallway to the dining area will remain open.

You can put the wardrobe in the hallway, right, or what do you mean?

A reasonable wardrobe is 60cm deep and for 4 people at least 1.20m wide, I would say. With your hallway measuring 2.50m - 1m for the stairs and 60cm for the wardrobe, there remains 90cm of passage. That would be too little for me in the entrance area.

I think if we install a bigger door in the guest WC, it will get quite tight in terms of space since it is already so small, right?

That's true. But there is also a narrower door planned to the pantry (which I would paint anyway) and to the storage room on the upper floor. On second glance, I also notice that the door to the guest WC also opens into the hallway. That means your doors differ not only in width; for the guest WC the door leaf is on the hallway side and for the utility room on the room side. That is not acceptable to me. And since we are on the topic of the guest WC: Have you only planned a shower in the house?

I have to look for this L solution.

Take a look here:

Hall to the dining area remains open.

Have you considered the issues of sound transmission and drafts?

Keep in mind that you have drawn the outdoor unit of the heating system at the location of the garage.

Yes, we have, that will be changed in the final planning.

A reasonable wardrobe is 60 cm deep and at least 1.20 m wide for 4 people, I would say. With your hallway of 2.50 m – 1 m for the stairs and 60 cm for the wardrobe, there are 90 cm of passage left. That would be too little for me in the entrance area.

The plan was once to place the wardrobe under the stairs. They are open. I still have to check the measurements.

On second look, I also notice that the door to the guest WC also opens into the hallway. That means your doors not only differ in width; for the door to the guest WC the door leaf is on the hallway side and for the utility room on the room side. That doesn’t work for me at all.
And while we are on the guest WC. Have you only planned one shower in the house?

Yes, we still have to have that changed as well. Really not acceptable.
Only one shower is planned. Also because of the space.

Have you considered the issues of sound transmission and drafts?

Not really.
We have a ventilation system, if that even matters here.

Somehow, I find the dining area and living area a bit awkward. Both have a section at the bottom of the plan that cannot be used properly. That’s about 6 sqm in total. The bay window with an interior width of 251 cm is also not really usable for the table... you can already see it, otherwise you can’t get past the corners at all.

The TV distance is probably still a bit large for a current standard TV.

How is the transition between hallway and living room intended? Looks kind of open. If there is a wardrobe under the stairs... hmm.

For the children's rooms, I would probably prefer wider windows with a sill instead. In my opinion, they let the light into the room better, at least over a broader area.

I find it a bit risky for Child II. If they want to go to the toilet at night "half-asleep," they have to pass right by the top of the stairs. It wouldn't be suitable for me, unless there is a gate there.

For the children's rooms, I would probably prefer wider windows with a railing instead. In my opinion, they let light into the room better, definitely over a wider area.

My regular TV is 165 cm large.
The transition to the hallway was intended to be open.
I found floor-to-ceiling windows nicer.
My wife also preferred wider ones. But a French balcony is not an option for our house.
