Floor plan optimization city villa + fill consideration

In the 2D plans, the doll furniture can still be seen as a kind of post-it notes that merely mark the location of the real furniture – but in 3D it basically becomes a lie repeated under oath, since the client knows 3D from the world of Virtual Reality and does not expect to fall into a virtual falsehood.

I keep hearing about the doll furniture. It may be true that this is often the case. But if I adjust the dimensions of the furniture in my program to real measurements (existing or Ikea), then the proportions should be correct, right? Or do you also doubt that?
The same goes for the 3D "walk-through": in Sweethome3D there is always a "viewer figure" on the 2D plan. If I make sure that this is not standing in impossible positions, then that is probably not a fantasy view, is it?
This also led me to possibly go with 2 children’s rooms, since with full equipment (wardrobe, bed, and desk) 3 children’s rooms rather looked like closets. In the 3D view of sh3d.
On 2D I would have said the rooms are all 0.5 sqm larger than the current one, so that fits.

So the 3D model from Sh3d really helps me a lot.

Then it should at least be correct. But I seem to recall from the forum views on kitchen fronts that would have required a glass wall.

I have not seen reason to doubt that yet. Only with the "default furniture" do I get the impression that children's desks and fantasy-measure sofas are used - as well as kitchen tables that look like dinner tables but are more the size for peeling potatoes.

So the 3D model from Sh3d helps me a lot.

I am glad for everyone whom even a flawed tool helps forward. But there are also many cases where a 3D representation is believed more than it should be. Especially for those with difficulties in proportions and perspective, the representations of such programs are (false) certifications of what was already fudged in the 2D plan. Many amateur planners see 3D as a kind of "TÜV" for their designs. And in this sense, plans with gross errors often get a "seal," namely too steeply planned stairs and the like.

If someone enters the correct measurements, they are not dollhouse furniture. Unless a 2-seater for 5 people is planned.

2-D is enough for me, 3-D confuses me. I'm not sure if I even have anything in 3-D of our house.

It's good if these views help. The architect's recommendation was to equip the house as a model with real furniture. Then maybe you pull the chair out once and realize uh this is tight.

Do you find a guest toilet next to a living room wall disturbing? Can you always hear the flushing?

We have it like that and it doesn't bother at all, however the wall is 24 cm thick and the sanitary fixtures are installed in a pre-wall installation in front of it.

Best regards Sabine

the wall is actually 24 cm thick and the sanitary fixtures are installed in a pre-wall installation in front of it.

Was the wall deliberately built that thick? With what material? And can you really hear nothing there?
