World’s Most Expensive Apartment Sold to Unnamed Buyer

It boasts a penthouse view over Central London, a private wine-tasting facility and an underground passage to a Heston Blumenthal restaurant, reports DailyMail.co.uk.

Throw in security measures a James Bond villain would be proud of and a ‘panic room’ in case things go wrong, and you would expect to pay a high price.

But even estate agents could not contain their amazement yesterday as a London property was on the verge of being sold for £140million – making it the most expensive flat in the world.

The two-floor apartment in the One Hyde Park, Knightsbridge block has floor-to-ceiling windows, its own car park and access to a host of spas and squash courts.

Naturally enough the residence has security features including bullet-proof windows, SAS-trained security guards, an air purifier to frustrate poison gas attacks and a ‘panic room’ where the owners can retreat in safety should they be targeted by kidnappers or robbers.

The previous most expensive flat was valued at £115million in a rival Central London development at St James’s Square in 2008.

The identity of the new owner is shrouded in secrecy.

The property, designed by architect Lord (Richard) Rogers’s firm, Rogers Stirk Harbour and Partners, is being marketed by developer brothers Christian and Nick Candy.
