For deep-pocketed travellers with a love of the high seas, an apartment on this luxury ocean liner might appeal.
The 971-foot long Utopia, which is currently under construction in South Korea, boasts 190 residential units, with the properties ranging from $4.4 million ($7 million) to $36 million ($54 million).
Artist renderings and showroom mock-ups reveal what the opulent vessel will look like, with the classically-styled apartments boasting ocean views, private hot tubs, sundecks, cinema rooms and walk-in closets.
The rooms will be finished with the finest fixtures and fittings, with one mock-up showing a kitchen decked out with thick marble counter tops and slick stainless steel appliances.
Another shows a bathroom so large that there is a plush armchair to recline in after having a wash. Again, the place is clad with slabs of marble and there is a TV set within a mahogany cabinet.
On decks 15 and 16, the Utopia website states, will be private members club, where residents can mingle.
This will house a luxury restaurant where guest preferences will be registered, so their favourite wines will be "decanted and ready to pour" and meals will be tailored to tastes.
Over in the ship's lounge, an array of beverages will be available, from "properly-shaken martinis" to cups of "fresh ginger tea".
Other communal amenities on the residential boat will include a medical centre, stores, a casino, nightclub, and a state-of-the-art gym, with a spread of fitness classes on offer.
For those who don't have a few million spare, the Utopia will also be home to a hotel.
There will be 206 guest rooms aboard the ship, with the categories including "suites", "luxury suites" and "grand suites".
The Utopia - which is a build project costing around $1 billion - was the brainchild of David Robb, a successful financier and Harvard business school graduate.
Talk of the liner emerged back in 2008 and there has been much excitement about the ship's delivery since.
ccording to an article in The Wall Street Journal, dated to 2013, nearly 80 clients had signed or were in the process of negotiating purchase contracts.
So that they could get a taste of what bang they were getting for their buck, a 3,000-square-foot showroom for potential buyers was set up on Rodeo Drive in Beverly Hills, California.
In a recent interview with Business Insider, Robb revealed most of the buyers so far are business people and philanthropically-minded individuals.
He also noted that the physical launch of the ship is still three-and-a-half years out.
There is no word on the ship's itinerary but Robb explained that it will travel to "remote parts of the world".
He concluded: "We describe it as the largest private yacht in the world. Cruise ships are built to last approximately 25 to 30 years.
"We're building Utopia to a 100-year specification. There's nothing like that in the world."
