I have followed the further discussion in the green forum. Only there I don’t like to publish my own suggestions. So here ;)
Kitchen now also with east window ... very nice on a sunny summer morning like right now.
Pantry/storage room as a walk-through room with 2x120 cm storage space. The rest can then disappear in the basement.
Kitchen with sunny east seating area and a nice view to the south.
Fireplace now on the exterior wall.
Hallway with niche for the wardrobe, bathroom designed so that the shower also has space. Identical bathroom, by the way, on the upper floor.
Partition wall in the living area for a possible sleeping area could be done at 360 cm, as on the upper floor. Then a fireplace can at least continue to be used. Living area then rather shrinks to 2 comfortable armchairs.
On the upper floor, the master bedroom was also placed on the west side. This allows better positioning of the bathroom and dressing room (really a dressing room) with 600 cm of closet.
Maybe there are some ideas for you.
Oh, by the way, I positioned the house about 50 cm further south because of the staircase windows :oops:
P.S: The program is glitching right now .. it labeled everything as Room 1 ;)
