Really makes me wonder what drives him. For many people it's the money, but with him it doesn't seem that way. But I haven't read too much about him, so if anyone has insight I'd love to hear about it.
For some people, money is not for buying things, but just for keeping score. That can make it rewarding and addictive to accumulate money, even if you don't buy anything (like a giant house) with it.
The score keeping aspect makes it interesting, just like playing tennis while keeping score is more interesting than just hitting a ball back and forth across the net without counting.
I can recommend the Acquired (podcast) 3 part series on Berkshire.
There was a cool fact in there that he sees every price tag as the opportunity cost with compounding interest.
Homes and physical community are a pretty personal thing.
Also, given that he is a billionaire, I do kind of assume that he has paid money to upgrade his home at some point, probably also owns additional homes elsewhere, maybe has done other things with his vast amount of money that normal people don't do, that are still consistent with living at the same address as when he was 28.
Read his biography - "The Snowball: Warren Buffett and the Business of Life". It's quite long but pretty accurate picture of the man and what drives him. His answer was always that he just loves what he does and he does it with people he loves (Charlie). One can hardly ask for more in life.
