KG: The entrance to the granny flat works for dynamic students. For older people, more space is needed, e.g., for walkers, also significantly more movement area and a good wardrobe. The closet space in the bedroom is too small; due to the room layout, the space between the bed and the wall is also too tight. The path to the other generations through the hallways without natural light is not very appealing.
EG: The entrance is dark; the rest feels like an inflated catalog floor plan.
DG: For 5 people, one bathroom on the floor is not enough; even with the bathroom on the ground floor, bottlenecks can occur. Considering the space consumption in the existing design, this is incomprehensible. Likewise, with this size, a parents' wing should be a matter of course; it is more relaxed for all involved.
outside: Maybe tidy up a bit more.
Overall, inefficiency should be reduced and functionality increased.
