its absolutely gigantic but the individual rooms themselves are kinda meh for the price and what you would expect for a typical home. So what you are buy is a huge load of middle class living space with amenities.
I watched the entire video-it was fun to watch it, but it would not be fun living in such a huge house. I’m thinking because of the sheer size of the place, it might serve better as a medical treatment center, health spa, even a high class restaurant and nightclub. The possibilities are endless.
But NOT a home, especially for an egomaniac.
