I guess it’s because of much lower use of off-the-shelf materials. Partly that’s unavoidable. The hull has a unique shape, and that means you can’t just put standard kitchens, bathtubs, etc. in if you want your design to shout ‘luxury’. For yachts in this category, I guess even the door handles, flooring, etc. are custom designed. This ship also wil have huge carbon masts that are unique in the world. That adds up. I guess Apple’s spaceship office similarly is quite a bit more expensive per m² than your regular office building.
