Sorry, I meant the children's bathroom on the left in the corner in the original floor plan. I'm totally confused. You redrew it as a bedroom in a line with the dressing room, through which you enter. I can't wrap my head around that. For me, this left room cannot be enlarged at all because of the stairs.
I also don't know if it really looks good with the stairs. The half railing on the stairs on the upper floor is blocked, if you know what I mean. Doesn't that look ugly then? Can the floor plan upstairs be saved in any other way? The bedroom should be big enough with a wall to watch TV. We could also do without a dressing room, but we want our own bathroom.
