That can definitely be well filled with life.
Hmm… if the entrance hall is a hall, so no longer just a foyer, then personally I don’t find it nice. It is bigger than a standard living room in a comfort apartment. It also has to be constantly frequented to go upstairs or to the toilet. What impresses me, however, is the air space above – if there is an amazing lamp hanging down there, it really makes an impression. However, even if you have the necessary money, you probably have to consider whether you want to distance yourself so far from an average standard of living with such a “size” or stop pushing the boundaries at some point in this “big size” thing.
Everything is eventually saturated and excessive: what use is a bouillabaisse if there’s so much premium fish in it that there’s no liquid left in the soup?
I don’t want to preach here, but since the house is not affordable or buildable like that anyway, maybe it’s worth considering that even half a hall, a generous foyer, can be much more valuable for the house than such a palace thing.
I would probably rather stick to built-in furniture that furnish the house or an expensive staircase, and save on cumbersome size.
