Final stage floor plan: Is there still potential here?

I have been going back and forth drawing all this time because of all your suggestions. Crazy. And I actually thought in the last few days that we were basically done. Unfortunately, combining the bedroom and dressing room doesn’t work, because although we go to bed together, we always get up with about 1-1.5 hours difference. (I am an early riser )

Do you mean the sofa on the northern or the western exterior wall?

Your comment about the staircase is really great! We definitely have to clarify that.

What still bothers me a bit is that in Katja’s design so much space upstairs is taken up by the hallway.

I would definitely add a large window in the living room on the north side. Whether the sofa is then on the east or west side is surely a matter of taste. The existing door in the living room can also be made bigger. In the original floor plan, it is far too dark. You can really make much more out of it...

Combining bedroom and dressing room is unfortunately not possible, because although we go to bed together, we always get up with about 1-1.5 hours difference. (I am an early riser )

So before I get such a half-baked dressing room, I would first consider ypg's idea of getting the optimum out of it with suitable built-in wardrobes under the slant and then simply go the old-fashioned way: laying out clothes in the bathroom the night before. With all this dressing-room-must-have hype, people completely forget that this also works...

But then also every weekend already lays out the jogging pants. And then I want to tinker at the car and have taken out the wrong pants, or have to go to the city again. No, we currently have an unused children's room in the apartment, which is misused as a dressing room and that is simply divine. It is a decision we have made for ourselves. Every time someone is sick, the other one moves out of the bedroom and then sleeps for a few days in the children’s/dressing room. And with the clothes, it is a huge effort every time, because you just don't always remember to lay them out, or in the morning you realize "Oh, today you have something important, you have to wear a shirt."

What still bugs me a bit is that in Katja’s design so much space on the upper floor is taken up by the hallway.

Huh? That's 30 cm more depth (150 cm instead of the 120 cm you planned), and I would definitely keep it that way, otherwise you won't even have space to pass each other side by side upstairs.

But then you also have to lay out your jogging pants every weekend. And then I want to tinker on the car and have taken out the wrong pants, or have to go back to town. No, we currently have an unused children's room in the apartment that is being used as a dressing room, and that's simply divine. It's a decision we made for ourselves. Every time someone is sick, the other moves out of the bedroom and then sleeps in the children's/dressing room for a few days. And with the clothes, it's always a huge effort because you just don't always remember to lay things out, or you realize in the morning "Oh, today you have something important, so you have to wear a shirt"

Good planning is everything. Well, I can think 10 hours ahead. We currently have no dressing room and get up separately, works great. It's a matter of organization and discipline. Since I can hardly think clearly in the morning anyway, I'll probably already plan what to wear the evening before even with a dressing room. If I ride my bike to work, I pack the backpack with clothes in the evening anyway and lay out the cycling clothes. Of course, a locked dressing room is nice, but giving up living space used for other purposes doesn't make sense. And a well-built wardrobe can certainly serve as a room divider. Then just install a door instead of only a passage, but the wall is saved. And you don’t rampage when you dress or undress. And as long as you have no children or only one child, you can "misuse" a room as a dressing room, and if you have two toddlers, greetings to the girlfriend (and then probably wife): you can forget about sleeping in late at the latest then. Because dressing room or not, by half past five at the latest the dear kids are standing in front of the parents’ bed wanting to get up or at least come cuddle in bed.

P.s. I would combine the dressing room and bedroom and completely close it off under the slope with sliding doors. Then you have enough space behind for shelves and clothes rails. A seating area can then be created in the dormer.

So?
