What the property is

Buckingham Palace is the official residence of the British monarch and is treated in rankings as a residential palace, even though it is not privately owned. It is located in central London and is used for state functions, ceremonies, and as the administrative headquarters of the monarchy.

Value and scale

Recent 2024–2025 lists of the world’s most expensive homes consistently estimate Buckingham Palace’s value at about 4.9 billion dollars, placing it first ahead of properties like Antilia in Mumbai (about 2 billion dollars). The palace has hundreds of rooms, including state rooms, staff quarters, and guest suites, plus extensive grounds, which contributes to its extremely high valuation.
