The first step has been taken today

I'll just throw in a few questions here without any judgment.

What are you doing with the space behind the shower?
Is a walk-in shower planned? Then your drains would come out in the kitchen.
In general, the wastewater pipes from the bathroom will certainly come down somewhere in the kitchen.
Have you taken that into account in the kitchen planning?

Separating the dressing room from the bedroom was surely your wish.

Have you thought about where shoes, jackets, etc. will go in the hallway? There is certainly some space under the stairs and between the utility room and the living room door, but is that enough for you?

Is the exterior door in the utility room planned like that, or should it rather lead under the carport? For the house view, of course, an additional window would then be necessary.

Where is the TV supposed to stand? Does the small balcony door maybe take up the space for it?

If the dark spot is supposed to be a wood-burning stove, don’t underestimate the space required for a stove.
Generally take another look at the sizes of the furniture items. I find a sofa with 60-70 cm seat depth a bit too narrow.

Can you all manage to get ready early in one bathroom, or would a second shower in the guest WC make sense?

Do the views from the gable sides fit?

I find a nice double-leaf entrance door beautiful. But if the staircase then starts directly at the fixed side of the entrance door, it looks like there wasn’t enough space. That's just my personal opinion, since it’s like that in many model houses.

What are you doing with the space behind the shower? Is a floor-to-ceiling shower planned? Then you would come out with the drains in the kitchen. Generally, the wastewater pipes from the bathroom will certainly come down somewhere in the kitchen. Have you taken this into account in the kitchen planning?

What exactly do you mean – that the corresponding "pipes" can be seen in the kitchen? At least the builder did not mention that.

Separating the dressing room from the bedroom was certainly your wish. But it is not quite the final plan – there is an access from the bedroom.

Have you thought about where shoes, jackets, etc. will go in the hallway? There is certainly some space under the stairs and between the utility room and the living room door, but is that enough for you? Good point – we hope that we can rather move shoes towards the utility room – but the hallway is certainly not very generous in favor of the living/dining area.

Is the exterior door planned in the utility room, or should it rather go under the carport? For the house view, an additional window would then of course be necessary. It should be like that.

Where should the TV be placed? Does the small balcony door perhaps take up the space there? The TV should be on the wall – the question is whether it "looks reasonable" if you place a couch in front of a floor-to-ceiling window (which is no longer supposed to be a patio door).

If the dark spot is supposed to be a wood-burning stove, then don’t underestimate the space requirements of a wood stove. Take another look at the sizes of the furnishings in general. I find a sofa with 60-70 cm seat depth a bit too narrow. We will do that; I also have some doubts about whether a plasma TV near the stove might be "too much."

Can you all manage to get through one bathroom early enough, or would a second shower in the guest WC still be useful? – We will probably manage that quite well – but certainly an important point.

Do the views from the gable sides fit?

I find a nice double-leaf front door beautiful. But if the stairway then starts directly at the solid side of the front door, it looks as though there wasn’t enough space. But that is just my personal opinion, because that is how it is in many show houses.

Thank you again – oh, by the way, the items, seating groups, etc. that were drawn in were simply included by the builder for illustration.

Shower
According to our construction company and site supervisor, the connections for the floor-to-ceiling shower come out in the room underneath the floor-to-ceiling shower directly at the spot where the floor-to-ceiling shower is located. These would then have to be routed along the ceiling to the edge and then downwards with the normal pipes. Such a boxing in the middle of the room looks stupid. Dropping the entire ceiling or just a part where, for example, spotlights are installed would be another alternative. In normal showers, the drain already goes through the cladding walls in the bathroom into the sewage shaft.
The question for you would be, where does the shaft go down through the kitchen? As a layperson, I would say that the connections from the tub, the toilet, and the shower are bundled in the cladding wall and then routed down through the kitchen in the corner behind the shower.
Therefore the note regarding kitchen planning.

Living room
Personally, I don’t like floor-to-ceiling windows because you can’t place anything in front of them. Or you place something in front of them and it looks stupid. We want to have nice wide double-leaf windows. Maybe that would be an alternative. For design reasons, this would of course have to be done in the dining area as well.
I don’t know how big the plasma is and how big the fireplace should be, but I think about 4m of wall space should be enough.

Hallway/Utility room
Maybe one more idea regarding the coatroom.
Insert a room of the same size above the guest toilet as a coatroom and have the further passage to the utility room inside there. Or swap the coatroom and guest toilet.

Drawn-in objects
In many brochures and sample floor plans, objects are included. Often, however, the objects are drawn smaller so that it looks nicely spacious. In the end, you have to sit on the bed to be able to open the wardrobe doors of the bedroom closet or have to buy a wardrobe with sliding doors.
