3. Streets of Monaco – $1.1 billion
As the name hints, this floating extravagance project will be designed to replicate the city of Monaco, or to be more precise, a section of Monte Carlo. This vessel will be built by Yacht Island Design of Derbyshire County in England and is expected to reach a price over $1.1 Billion. The price will go this high due to its unconventional design, which will feature scaled-down replicas of famous landmarks from Monaco, such as the Monte Carlo Casino, racetrack, Hotel de Paris, La Rascasse, Loews Hotes and Cafe de Paris. Moreover, the Streets of Monaco boasts swimming pools, tennis courts, a cafè-bar with underwater sights, a mini waterfall, helicopters and a submarine.
