Optimize new single-family house floor plan

I would reconsider the staircase, the hallway is way too big and yet there is no proper cloakroom. Upstairs in the corridor, too much space is lost. The children's rooms have already been mentioned, not really well laid out. The living area is not exactly spacious for 5 people either.

That is really a great design, you have made me very happy with it: pencil drawing instead of Maggi Fix for Traumhaus 3D # planned with round decimeters instead of believing in half centimeters and further target=actual false assumptions would be seriously feasible # walls all initially planned as load-bearing instead of rooms becoming 6 cm narrower afterwards # walls placed on top of each other (but probably still the upper floor built on the ground floor, an excusable amateur mistake). And of course because you are asking now and not only when the idiot is already planning in detail

I would now of course like to see the original model for comparison. The upper floor requires a high knee wall or would have to be straight-walled up to the ceiling right away. But you will have to go “back to square one” anyway: behind the staircase I paint a question mark regarding its dimensions – and because its position is not quite right either, the shot in the foot is not so bad. It only works with larger lengths at the cost of bottlenecks in the hallway. What kind of element is that supposed to be as a living room entrance: a door flanked by side panels, but with wall sections in between?

That's quite a great design, you've really made me happy with this: pencil drawing instead of Maggi Fix for Traumhaus 3D # planned with round decimeters instead of assuming half centimeters and other Soll=Ist misassumptions that would be seriously feasible # walls initially planned as all load-bearing instead of rooms becoming 6 cm narrower later on # walls stacked on top of each other (but probably the upper floor is still built on the ground floor, an excusable layman's mistake). And of course with the fact that you ask now and not only when the clown is already in detailed planning

I would now of course like to see the original model for comparison. The upper floor requires a high knee wall or would have to be straight and room-height right away. But you will have to "go back to start" anyway: I put a question mark behind the staircase regarding its dimensions – and because its position is also not quite right, the shot in the dark isn't so bad. With greater lengths, it only works at the cost of bottlenecks in the hallway. What is that element supposed to be as the living room entrance: a door flanked by side panels, but with wall sections in between?

The base for this was ARGE-HAUS "Stadtvilla 3". That also explains the large hallway with the staircase inside and the shape of the 3 children's rooms.
The fact that 3 children's rooms were already included and some other rooms were easily modifiable for us was a reason for choosing this base.

Living room entrance = glass door in glass wall. So that the hallway is filled with light.

Room height in the ground floor and upper floor should each be 2.55 m, i.e. flat roof. So far, we have found no reason for higher room height.

In ARGE, exterior walls are always 36.5 cm and interior (load-bearing) 17.5 cm standard. We have initially adopted this everywhere.

OK, so the staircase needs to be considered more carefully ...

but I would gladly pay for the few reinforcing bars if Child 3 grows bigger, Child 2 has one corner less in the room (corners also cost money), and Child 2 then enlarges at the expense of Child 1...

We have played this through and currently see it as follows:
For Child 1, the room would then be too narrow.
For Child 2, the wall would be without a corner, but this is the wall to which the door opens. The missing corner would therefore have no advantage, but would even be a disadvantage, since a piece of furniture could start behind the corner (e.g. a cupboard) and without the corner one would be more likely to bump into it or feel cramped.

The basis for this was ARGE-HAUS "Stadtvilla 3".

I could not identify the model on their website.
