Now, honestly... a residential basement floor is nothing more than a residential ground floor without a hillside location. And nobody argues that it would be fundamentally too dark or that the neighbor could plant a 4m hedge (which, by the way, is not that easy in BW). Dark rooms can be solved with large windows
Why you would run downstairs for every bottle of water is beyond me. The house access is from the north, the living areas would sensibly of course face the valley, that is, to the south. Ergo, you would at most carry the crates down, never up. In the worst case, you could also have some kind of dumbwaiter installed to transport the groceries downstairs. Or – cheaper and anyway sensible – you plan a path down that can also be used with a hand truck.
