Hong Kong remains the most expensive city in the world for billionaire trophy homes, a report by international property consultancy Savills says.
"Billionaire" properties in the city average £7,200 (HK$84,400) per square foot for an average home of 5,200 sq ft, it says.
The report calculated a price index of homes for the super rich in 10 top cities around the world at the end of last year.
Savills compared homes that members of an "executive unit" - a group of people who might start up or expand a global business in any country - would be likely to choose in each of the 10 cities.
Tokyo ranks second at £5,000 per sq ft for an average flat of 16,000 sq ft, and London third at £3,500 per sq ft for an average flat of 7,900 sq ft.
Paris, Moscow, New York, Shanghai, Singapore, Mumbai and Sydney round out the list.
