For the sake of completeness and because asked again - here is the planner's draft, which we did not like that much. This is probably a standard draft from this general contractor. However, it has only 134 sqm, volume of 730 cbm. So theoretically it might still be possible to enlarge it a bit if that does not completely change the statics.
KN 1.5m, DN 38°
What we liked:
- spacious SPK option under the stairs
- separate accessible utility room on the upper floor, separated from the children's rooms by a hallway (noise)
What we did not like:
- dirty corridor is crossed when entering the shower room downstairs
- L-shape of the living area only hinted at
- living area very narrow (approx. 3.2 m)
- house technology in the south, guest room in the north
- little wardrobe space, but maybe the technical room can be used for this
- narrow children's rooms that are not easy to arrange
- one children's room in the north, bathroom in the south
- lot of hallway space on the upper floor in the south
Maybe the mentioned dislikes can be mostly resolved through slight modifications?
