Some of the world’s biggest homes, each making very different use of space. 

The tiny home movement has grown exponentially over the last few years. But have you ever wondered what the world’s biggest homes look like and where they are?


Personally, we’re comfortable in more modest dwellings – but for fun (and in no particular order), we take a look at 11 of the biggest homes.


Each one is architecturally unique and makes very different use of space.


Antilia, Mumbai, India

This towering 27-storey skyscraper has become a recognisable part of downtown Mumbai’s skyline. The US$2-billion building is currently the largest and most expensive private residence in the world.

Antilia is home to Mukesh Ambani, the richest person in India in 2018, and his extended family. His net worth in February 2020 was US$57 billion.


As far as homes go, Antilia is mind-bogglingly big, with a floor space of just over 37,000 square metres. The name comes from that of a mythical island in the Atlantic Ocean.


Taohuayuan, Suzhou, China

This stunning, traditional-style mansion covers over 6,700 square metres. It includes 32 bedrooms, a huge wine cellar and a lakeside swimming pool.


It’s the most expensive home ever sold in mainland China, at US$149 million.

The mansion and gardens were styled after the Classical Gardens of Suzhou, a UNESCO heritage site. The name Taohuayuan translates to utopia or peace blossom land. Taohuayuan is located on a private island in China’s largest lake, Dushi.

The Safra family is off limits to the curious, so not much is known about the interior. It’s said to include more than 130 rooms.


The building’s design features an interesting curved shape.


The One, Los Angeles, United States

The One was built in 2013 and has a living area of 9,290 square metres. Its master bedroom alone is more than 460 square metres.


The giga-mansion, as this type of mansion is becoming known, also features a bowling alley, walls made from jellyfish tanks, a 32-car garage and a private casino.

It was designed by architect Paul McClean and has been valued at US$500 million. If it’s sold, it’s likely to rank as the most expensive single family home in the United States.


Villa Leopolda, The French Riviera, France

Villa Leopolda was built by King Leopold II of Belgium more than 100 years ago.


The Villa was bought in 2008 for US$750 million by Lily Safra, of the Brazilian Safra family. This makes it one of the most expensive homes in the world.

The construction of Fairfield Pond was surrounded by controversy. Neighbours objected to the development and Rennert was accused of taking funds from his mining company to pay for it. Despite the rocky inception, the mansion was completed in the 1990s.


Witanhurst, London, United Kingdom

This classic mansion originally spanned 3,700 square metres. However, a modern renovation added two basements, more than doubling the square meterage.


The extension houses a pool, movie theatre, sauna, gym and additional parking spaces.
