A well-connected Luxist follower has written in to inform us of the identity of the buyer of the record-shattering $308 million Monaco penthouse (above) we just reported on. The new owner of the world's most expensive apartment we're told is Greek billionaire Constantine Alexander-Goulandris, a close friend and business associate of Russian oligarch Roman Abramovich. According to Wikipedia, the American-born Alexander-Goulandris, 47, who's based in Monaco, is an influential adviser to the Saudi royal family and the emirs of Qatar and Kuwait, as well as the leaders of the UAE and many of the world's largest oil companies.
In addition to Abramovich he's also close to Russian prime minister Vladimir Putin. Though not on Forbes' list of the world's richest people, he's said to be worth an estimated $15 billion thanks to investments in petroleum and energy shipping and real estate, including the Olympic Tower building in NYC. In addition to Monaco Alexander-Goulandris reportedly maintains residences in Paris, London, Antibes, New York and Hawaii. He also owns one of the largest yachts in the world, the Dubai-registered, 279-ft. Delma, and jets around on a Boeing 767 and two Gulfstream G550s.
UPDATE: The buyer was in fact a member of Dubai's royal family; Alexander-Goulandris acted as an adviser - read more here.
