Which one exactly is that now, meaning which #post number?
Yes, a guest WC with 2 sqm could go, but does that really make a difference?
If you remove a 2 sqm room somewhere, it can affect the entire overall design: sightlines, missing centimeters to properly place a dining table, suddenly you can create rooms where there was no possibility before (for example, you don't go from the living room directly into the toilet. Without the toilet, no problem anymore), you have one less door and thus more wall area and probably less hallway (i.e., you gain more than just an additional 2 sqm of usable space).
Long story short: Yes, that can make a huge difference! That’s why information like "could be removed" is extremely important.
By the way, the type of staircase makes an even bigger difference. The entire floor plan stands or falls with it.
If you now say: mini WC could go and the following staircase shapes are okay for us: x, y, z,... that makes
quite a bit of difference!
