Who doesn’t dream of living in a mansion with every breathtaking extravagance and luxury known to man?

I mean, be honest: we’d all LOVE to have that football field-sized swimming pool, in-room hot tub, swim-up bar, enormous picture windows, spectacular views, high-end furnishings, and cutting-edge smart home tech.

Some very select few people are simply fortunate enough to actually own and live in real-to-life mansions!

Below, we’ve collected a list of the 20 best modern mansions that are so luxurious and expensive they’ll make your eyes water, and guaranteed to make you dream about living in them.

While some of the mansions on this list were built many decades (even centuries!) ago, they’re still popular today and filled with all the most modern features and luxuries that make them truly timeless.

Beverly House, Beverly Hills, USA

You can’t have a list of the most modern and luxurious mansions in the world without featuring Beverly Hills—and this six-acre estate absolutely deserves a place of honor!

Designed by Gordon Kaufmann and built by Milton Getz, this gorgeous mansion combines Spanish and Italian influences, while offering tons of space, including a 50-foot entry hall, a large library that bookworms will love, a billiard room, an outer terrace that can accommodate 400 people, and even an art deco nightclub and wine cellar! Throw in the two projection rooms and a spa, and you’ll never have a reason to leave your home.

But that’s not all. Also on the property are a range of smaller homes that carry over the opulence and luxury from the main house, offering guests the once-in-a-lifetime overnight stay of their dreams.

Think this mansion looks familiar? You’ve probably seen it before—it was featured in both The Bodyguard and The Godfather.

Antilla, South Mumbai, India

Antilla South Mumbai India

This $1.4 billion mansion, which is owned by billionaire businessman Mukesh Ambani, is more like an apartment building than a house. It looks like something you’d see in an action movie, almost too amazing to be real.

It has 27 floors (complete with nine high-speed elevators), a multi-storey garage that can accommodate up to 168 cars (perfect for car collectors or anyone with tons of friends), a theater, ballroom, spa, temple, multiple terraced gardens, and – wait for it – three helipads!

And if that’s not enough to wrap your head around, Ambani and his family also have a snow room in the home. This is a room they use when the heat outside is too uncomfortable as the walls keep them cool by releasing man-made snowflakes. Seriously!

The Manor, Los Angeles, USA

The Manor is famous for being the largest home in Los Angeles and one of the dreamiest mansions you could ever call home.

56,000 square feet in size, with 123 rooms (14 of which are bedrooms), it’s filled with amenities such as a nightclub, barber shop, beauty salon, and bowling alley. It almost sounds like more of a full-sized shopping mall than a home!

Outside, the garden on the property offers five acres of space and features a tennis court, koi pond, citrus orchard, and multiple rose gardens.

This $160 million mansion has been remodeled over the years and it has some extra features that take its luxuriousness to the next level: a limestone exterior, a bathroom that includes both an LED screen and daybed, and a “closet” that looks more like an expensive and luxurious clothing shop than a wardrobe.

Middle Gap Road Mansion, Hong Kong, China

Sometimes what really makes a mansion luxurious isn’t just what’s inside it, but what surrounds the property.

This Hong Kong estate is surrounded by country park greenery which makes it super private–even in one of the busiest cities in the world!

Though not overly immense (it has just four bedrooms and four bathrooms), it’s located in one of the most popular gated communities in the city. The master suite has its own living area, a walk-in closet, an ensuite bathroom, a study room, a sunken bathtub, and a separate shower. The house also boasts a swimming pool from which you can enjoy views of the city.

It’s been described by some people as a “modest mansion”, thanks to its lack of over-the-top features, but it still costs you approximately $440.8 million to purchase thanks to its location on 6,000-odd square feet of prime urban Hong Kong real estate.

Odeon Tower Penthouse, Avenue de l’Annonciade, Monaco

Inside the penthouse, you’ll enjoy a kitchen on all floors (you know, to deal with those late-night cravings that crop up after water sliding), and six bedrooms. Living in this penthouse will feel like you’re at a five-star hotel – you get a caterer, 24-hour concierge service, a health club, and private chauffeur, all of which are features to make your life so much more comfortable.

This penthouse overlooks the French Riviera and Mediterranean ocean, and it offers awe-inspiring 360-degree views of the water that can be enjoyed by the home’s rooftop balcony and other outdoor spaces.
