Buckingham Palace tops the list as the priciest property at £4.9bn, followed by Istana Nurul Iman which is the official residence of Hassanal Bolkiah, the Sultan of Brunei which would be worth £3.01bn on the market today.
Calculating the cost per square metre, we estimate that the overall floor plan of Buckingham Palace is around 77,000m², which makes the cost per metre square a staggering £64,831. That’s almost 5000% more than the average price per square metre in Central London, which comes in at £11,523.
However, the £3bn Istana Nurul Iman residence is much better value for money. At 204,387m², it’s almost three times as big as Buckingham Palace and that results in a much lower price per square metre; £14,756.
Measuring in at just 5,310m², The Blue House, home to Moon Jae-In, the President of South Korea, has the highest land value at £276,635 per square metre.
Number 10 Downing Street comes next, with a land value of £175,274m², but keeping in mind this is for just 353m² of property.
