The world’s most expensive house is located in London, England.

Buckingham Palace, the official London residence of the king, is widely considered the most expensive house in the world, valued at around $4.9 billion. 

Buckingham Palace is far from a traditional house with 775 rooms and 50,000 people visiting each year for receptions, dinners, state banquets and other events, according to the royal family website.

This, of course, is outside the half million tourists who visit the destination each year. In 2023-2024, about 530,000 tourists visited Buckingham Palace, according to Statista. 

In addition to viewing the breathtaking palace, visitors often watch the famous Changing of the Guard ceremony.

For those who want a look inside Buckingham Palace, guests can view the state rooms in the summer as well as on select dates in the winter and spring when small guided tours are available, according to the Royal Collection Trust website.

Another home ranked as one of the most expensive is Antilia in Mumbai, India. 

Antilia holds the Guinness World Record for the “most expensive private house in the world.” 

The mansion is estimated to be worth between $1 billion and $2 billion, according to Architectural Digest India. 

It is owned by business magnate Mukesh Ambani, chairman and managing director of Reliance Industries.

The property also includes 168 parking spaces and three helipads. 

UN health agency says its decision is ‘based on the rising number and continuing geographic spread of cases’.

The World Health Organization (WHO) says it will keep its alert for mpox at the highest level amid a surge in cases.

A WHO committee made up of about a dozen independent experts made the decision at a meeting in Geneva on Friday, three months after the WHO first declared a public health emergency of global concern in August.

The WHO said its decision was “based on the rising number and continuing geographic spread of cases, operational challenges in the field, and the need to mount and sustain a cohesive response across countries and partners”.

There has been a surge in mpox cases this year, predominantly focused in the Democratic Republic of the Congo (DRC) and neighbouring countries.

A first batch of vaccines was rolled out last month and appears to have had an impact on containing cases of the highly contagious disease, but the United Nations agency has been waiting for substantial proof to discuss the impact of vaccinations.

The African Union’s health watchdog warned at the end of October that the mpox outbreak was still not under control and called for more resources to avoid a pandemic that it said could potentially be worse than COVID-19.

The virus is usually mild, but it can be fatal in rare cases.

Mpox is believed to have killed hundreds of people in the DRC and elsewhere last year as it also spread to Burundi, Kenya, Rwanda, Nigeria and Uganda, causing a continent-wide emergency.

The disease can be spread through close contact with an infected person, sexual activity or breathing in infectious particles. The virus then replicates and spreads to the lymph nodes, leading them to swell before further spreading and causing rashes or lesions.
