This time we're talking about the Odeon Tower in Monaco, a 49-story double skyscraper under construction in the most expensive real estate market on the planet. (Click here or on the image at right to see a slideshow on Yahoo! Homes.)
The Odeon is expected to have 70 luxury apartments, two "sky duplexes" of about 13,000 square feet -- and crowning it all, a five-floor, 35,500-square-foot "sky penthouse" with its own private swimming pool, according to press materials provided to Yahoo! Homes. (Related on Yahoo! Homes: A New York penthouse with a slide connecting two floors.)
The project won't even be finished before next year, but speculation is already rife over how much the penthouse will cost. $250 million? $280 million? $329 million? $387 million? The numbers seem impossible, even unreal. Yet a London estate agency did tell CNBC that sales are averaging about $7,700 per square foot, so if the penthouse keeps pace, that would mean a sale of more than $273 million.
Whatever the estimate, the consensus is that the home has a very real shot at the title of world's most expensive penthouse, currently held by London's One Hyde Park, where a penthouse reportedly sold for $212 million.
