Because what happens when you bring together an architect limited only by gravity and an owner with a bottomless wallet? You get a luxury house filled with bespoke features tailored exactly to your personality and taste.
And the sky’s the limit: that could mean an outdoor theatre overlooking the Mediterranean sea, an entirely circular building, or whole new levels of exciting tech.
These million dollar homes knew no limits when it came to furnishing or decorating. “Mega mansions” or “a million dollar house” doesn’t really cover it: the world’s biggest house comes with 240 bedrooms and 535 other rooms.
