ok thanks. That helps me to work with and think about it. I am happy to explain how it came about:
The three "stripes" emerged during the planning process:
Somewhere in the entrance area there should be a wardrobe, somewhere there has to be a staircase, and the hallway resulted not least because of the statics: In an earlier plan the staircase was integrated into the living area, meaning the wall between living and entrance, as it is planned now, did not exist then. Then there were two problems: If there is no wall in the living area, where do we put the TV? and secondly the statics, which according to the architect required a certain type of load-bearing element (wall/columns etc.).
You can see the area "that you can’t do anything with" like that, but isn’t it always like that with a wardrobe or a hallway? The wardrobe is 1.65 m wide, which corresponds to about 65 cm + 1 m of movement space in front. That should actually be usual.
The front door is exactly on the left wall for the reason you described: So that you don’t run into the stairs. You can certainly move the door a few cm to the right so that it can open further. Is that the problem you have with it? Or what else bothers you about it being on the left?
An alternative would ultimately be to make the hallway area wider if the door on the one hand is not supposed to lead to the stairs and at the same time should not be so far to the left. But then you lose even more space to the hallway. Or do you have another arrangement in mind?
In the bathroom – shame on me – I actually forgot to transfer the bathtub when tracing. It is located on the "upside down T"/the wall to the shower and toilet.
With the dressing room and the utility room you are probably bothered by the "tube-like" character?! I can’t really disagree with you there. Especially in the utility room, as mentioned in some previous posts, I am considering whether we should design it L-shaped by moving the wall and turning the stairwell 90° to the left. Currently we think that in the utility room wall space is more important than floor space when you want to place the usual suspects (washing machine, dryer, heat pump, inverter, electricity/water/internet connection, network distributor, control cabinet, fuse box)... in the end surely both are needed of course. And therefore we wouldn’t have the biggest concerns about the current "tube" either.
In an earlier plan we had a more square room in the dressing room with closet space on both sides for a while. Because of the floor plan and the position of the stairs, the current room shape and position resulted. The space is certainly not used very efficiently; no question.
And yes, if it were possible, my husband would have already long since changed the architect. He gets mad every time something new is presented to us and changes are made that were never agreed upon. Unfortunately, we are tied to the architect through the general contractor if we want the plot.
