...We don't know how the neighbor on the left side is building. If we had now placed the garage on the right, we would be closer to the neighbor and possibly fully in the house's shadow. That's why the garage is on the left.
You really have to read and enjoy this twice: building on a 0% probability out of ignorance before considering the 50/50 rule.
Unless there is an Alpine or Baltic Sea view to the north, clearly open the house to the south.
Garage can be at the bottom right of the plan. Then also the entrance there, shuffle the rooms once and you have full sun in the living area as well as the terrace in the southwest.
Otherwise, the design is nicely tidy. I think too tidy, for example, to the detriment of closet space in the bedroom. The large and symmetrical windows are not pleasing.
I don't like the living area at all. Not even this northwest window side. Why this compulsion for symmetry? It doesn't fit the house and doesn't exist upstairs either. Then you don't have to go all in on the narrow side.
The corridor between garage and house is too narrow at 1.25... we have 2 meters, and I definitely wouldn't recommend less. The garage casts a shadow over the terrace in the evening.
All the secondary rooms are on your chocolate/sunny side... [emoji20]
.......> My suggestion:
Garage east, stairs in the northeast, entrance southeast, etc.
Children's rooms in the southeast/southwest, etc...
Then nothing stands in the way of a sunny garden and sunny terrace in the southwest.
