Personal price limit for the house, including fittings: 450K
Preferred heating technology: air-to-water heat pump
If you had to give up, which details / additions

- Could not give up: home office, bedroom, children’s room
Why is the design the way it is now? For example,
The design is the result of:

On one hand, I find that very practical, but on the other hand, I’m concerned that we might have a noise insulation issue. The stairs transmit sound from sources like a washing machine much more than a wall would.

Try to replicate this with your current table and a chair. You should plan for at least 90cm (36 inches), preferably 100cm (39 inches), and then the other distance to the island will naturally become quite tight, especially when people are actually sitting at the table.

The bedroom would then be right next to the street. I would reconsider that if I were you. Yes, sigh, cobblestones can be quite tiring.

That should be enough. The T fitting also fits into an 11cm (4.3 inches) wall, so almost 1 meter (3.3 feet) in total. But 11cm (4.3 inches) wall thickness is actually closer to 11.5cm (4.5 inches). With plaster, the thickness is around 13–15cm (5.1–5.9 inches), and if tiled, it can be up to 18cm (7.1 inches). This also applies to the 90cm (35 inches) recesses for the toilet and shower. A bathtub will not be flush against the wall either. It can happen that the mason uses their tolerance and the stairwell shifts by 3cm (1.2 inches).
I wouldn’t plan everything (this applies to the entire design) down to the last centimeter so tightly that there’s hardly any room left.
You might have very limited options for placing light switches, for example in the cloakroom.
Regarding the bathroom, I would think carefully about the actual use of the shower stub.
Furthermore, the stairs are planned with dimensions that are not comfortable. Steps should ideally be 19cm/26cm (7.5 inches/10.2 inches). Even half a centimeter difference can be really uncomfortable. The stairwell is planned with a height of 210cm (6.9 feet). Again, plaster is applied on both sides here.
The door is too narrow for technical purposes and practical use: equipment and ladder should be able to pass through.
