You are planning the fireplace at the end of the stairs on the ground floor. Where is the chimney supposed to go then? Usually, it goes straight up.
How do you want to get into the bathroom? The door where planned is not even 2 meters high.
Combine the broom closet and the bathroom into the utility room.
Make the kitchen bigger.
Small bathroom next to the front door.
So, I have swapped the utility room and bathroom and enlarged the kitchen accordingly.
Oh dear, what am I supposed to do now with all the space in the kitchen? Now it might actually become interesting to swap the living area with the kitchen and add a pantry, right?
It feels like the utility room could still be 20 cm smaller.

I still have to find a place for the fireplace, though. I’ll continue tomorrow. See you then and thanks in advance.
