No, I didn’t do that! So, I didn’t just attach a room onto the building...

And sorry, but what am I supposed to make of the last sentence as the person asking the question...?

Not the entire room, but only the additional floor area of the extra room that exceeded the total. But even that isn’t exactly a groundbreaking design technique, mersteselber, right?

Since you mentioned in the other thread that there are few concrete suggestions for improvement, I have made some slight adjustments to your floor plan. Overall, I like your second version much better, but I’m still bothered by that projection (even though it is now on the south side) and the lack of space at the top of the dressing room.

What did I do? I aligned the ground floor and upper floor on the south side exactly in the middle. This means the ground floor became smaller, and the upper floor correspondingly larger. The total area remains the same, so it stays cost-neutral with your builder. To reduce the area on the ground floor, I simply removed the space-consuming wardrobe there and moved the bathroom and utility room closer to the entrance. There was hardly enough room to move in front of the wardrobe cabinets anyway. The utility room is now somewhat larger, but narrower. The bathroom is also a bit bigger. There is now a large wardrobe. Possible windows on the ground floor are indicated in blue. The hallway looks narrow on the plan, but it will feel different in reality because of the staircase. You could still add a storage room under the stairs. On the upper floor, I simply used the space for a larger bedroom and a bigger dressing room.

Looks good. I like it, although I would personally move a few things (door to the utility room or dressing room), but those are just personal preferences. The window placement isn’t much of an issue here either – everything should fit well, including balance and harmony.

@Würfel*: thank you very much for your thoughts and adjustments to the floor plan. This version definitely looks better to us.

Last night we spent a long time reviewing the floor plans again and found a major drawback to this version: when you enter the open kitchen/dining/living area, you immediately "walk into" the dining table/kitchen island. It feels a bit chaotic.

So we went back to the other floor plan and slightly adjusted the exterior dimensions. It would be great if you could share your thoughts on this one as well.
For us, the biggest downside right now is the relatively small walk-in closet.

Sorry, I don’t see that at all.

To me, @Würfel*’s suggestion is by far more balanced, harmonious, and functional.

I don’t understand the idea of running towards the dining table/kitchen island at all. First of all, look at the dimensions—there is clearly enough space. You’re putting the guest toilet back in the center of the house.

But it’s your house, so if you like it better that way... The ground floor is basically the starting draft anyway...
