1. Private Submarines

Why settle for a yacht when you can explore the depths of the ocean in your own private submarine? Billionaires are investing in personal submersibles to navigate underwater worlds in complete privacy. These high-tech submarines come equipped with:

360-degree panoramic windows for breathtaking views
Custom interiors with plush seating and entertainment systems

Private submarines are not just for deep-sea adventures; some are even designed for luxury travel between private islands. Companies like Triton Submarines specialize in crafting bespoke personal submarines for the ultra-rich.

A single luxury submarine can cost anywhere between $2 million and $80 million, depending on customization. These vessels offer billionaires the ability to explore the ocean in absolute comfort, a privilege few will ever experience.

Owning a penthouse isn’t enough for some billionaires. Instead, they’re building entire skyscrapers for their personal use. These luxury towers often include:

Multi-floor residences with private elevators
Indoor swimming pools and personal wellness centers
Helipads for instant city-to-city travel

A prime example of this trend is the Antilia in Mumbai, a 27-story private residence owned by billionaire Mukesh Ambani. The residence is valued at over $2 billion, making it one of the most expensive homes in the world.

For billionaires who prefer city living, personal skyscrapers offer unparalleled privacy, security, and convenience. Some even include private airports on the top floors for seamless global travel.

3. Custom-Built Superyachts with Underwater Lounges

A regular yacht isn’t enough for billionaires. The newest trend is superyachts featuring underwater lounges and onboard submarines. These floating palaces include:

The superyacht Azzam, owned by the Emir of Abu Dhabi, is valued at $600 million and is one of the longest yachts in the world at 590 feet. For an idea of extreme luxury, check out Lürssen’s custom superyacht designs.

Owning a superyacht is not just about luxury; it’s about mobility. Some billionaires live onboard their yachts year-round, traveling between private islands, avoiding taxes, and experiencing ultimate freedom on the open sea.

For car enthusiasts with a fleet of exotic vehicles, an underground automated garage is the ultimate indulgence. These high-tech garages include:
