Repossessed flat with one of world's most exclusive addresses London's One Hyde Park development is offering up a repossessed one-bedroom apartment, for a cool $9 million. Photo: Simon Dawson What does $9 million buy one in London these days? An "entry level" one-bedroom flat - albeit with a seriously exclusive address: One Hyde Park. The 92 square metre apartment in London's most expensive residential complex - indeed, one of the world's most expensive - has been put back on the market after it was repossessed earlier this year. The ambitious project made headlines when it was first announced, and now stands as the most expensive apartment complex ever constructed in London. And it is truly a case of buyer beware - listed with an eye-watering price tag of £5.25 million ($9 million), the apartment is being described as "entry level," with just one bedroom, one bathroom and a reception room, as well as a very small kitchen tucked away behind a sliding door, replete with temperature-controlled wine storage system.

Location, location - after all, not many homeowners have as their local shops none other than Harrods and Harvey Nichols. High-end property agency Strutt & Parker said they had been appointed by receivers to arrange a quick sale of the repossessed flat - no details were given as to the identity of the previous owner or the reason for repossession. One Hyde Park was built by brothers Christian and Nick Candy (the latter is the husband of Australian pop star and Neighbours graduate Holly Valance), in conjunction with property developer Waterknights (owned by the Prime Minister of Qatar). Property developing brothers Christian, right, and Nick Candy launch One Hyde Park in 2011. Apartments at One Hyde Park were sold for almost double the price of other properties in the area, although real estate analysts have labelled it one of the "worst investments" in London. It is estimated One Hyde Park cost $1.1 billion to build. Residents at One Hyde Park reportedly include Ukraine's richest man, Rinat Akhmetov, the Kazakh singer Anar Aitzhanova and Naomi Campbell's boyfriend Vladislav Doronin. The luxury complex , which boasts only 86 apartments in the four-tower complex, sits in a narrow strip between Hyde Park and Knightsbridge. The block's high-security features include iris recognition in the lifts, panic rooms and bomb-proof windows, and all postal deliveries are X-rayed. Other features include a private spa, swimming pool, squash court, cinema, gym, golf simulator and a wine cellar. In addition to a concierge and valet, residents can access room service, which is delivered via a tunnel from the five-star Mandarin Oriental hotel next door.
