Me neither, and I didn't say that. It's simply that the symmetry-caused expansion of the areas described results in size dimensions into which a lot of money is sunk.
That's really how I see it too.
For example, you have a large bedroom. More than sufficient, only due to the symmetry. Since the symmetry here is shown on the south and west sides at the windows on the ground floor and upper floor, the large bedroom can hardly be fully utilized.
On the one hand, both windows will catch the heat of the sun (personally, for me, one window on the south is already enough for sweat outbreaks), on the other hand, the room would have enough space and room for that 3-meter wardrobe and dresser without the west window. The dressing room would then be left as an extra room.
The window in the dressing room takes away the sense of the room being cozy and allowing one to undress or change without prudery.
