The garage is located in the north, the street side (correct, bottom of the plan) is east, the kitchen faces south and the terrace/garden faces west.
Then I understand the room layout even less than I already do. The study upstairs is in the sun in the afternoon – you just end up sitting in front of the closed blinds. The bedroom is in a classic living area spot with windows all around.
Could it be that you tried to somehow minimize the hallway spaces as much as possible? I miss light axes there.
Giving up the balcony is daring – they are not just balcony space but also brilliant shading: It is always flooded with light, even more in winter than in summer, but in summer no light shines on the window surfaces if planned correctly.
At least for a house of this size, giving up the guest room strikes me as unusual.
Is there a particular reason why a storage room in the basement is only accessible through another? Unfortunately, that’s the case with me, we tried to avoid it, it’s annoying every time and really shouldn’t be necessary in a house of this size. Unless, of course, the order is part of the usage concept, such as the back room actually being the sauna and the front room being the changing/shower area.
