Buckingham Palace – $2.9 Billion
Coming in at number one , and claiming the title of the most expensive house in the world, is Buckingham Palace.
The palace is owned by the British Royal family and is one of a number of lavish properties in their portfolio.
It is located in the city of Westminster, London, and comprises of 775 rooms, 78 bathrooms, 92 offices and 19 staterooms. It’s been the official residence of the monarchy since 1873.
In terms of size, the palace checks in at approximately 828,000 square feet and the garden alone is 40 acres.
However, despite its impressive size and taking the title of the most expensive house in the world, it’s still not the largest palace in the world.
It’s estimated that if the palace were to be put up for sale; it would be somewhere in the region of $2.9 billion, but it’s highly unlikely it will ever happen.
