By way of comparison, the closest competitor in the States is the beachfront cottage in Carpenteria, Calif., that we wrote about last fall. At $5.3 million for a snug 641 square feet, it comes out to a paltry $7,000 per square foot.
So what does $225 million get you?
When it comes to luxury real estate, the U.S. is a relative bargain. The average price per square foot in the States tops out at about $1,400 in Malibu, Calif.; in New York, it's around $1,300. Compare that with the world's most expensive city, Monte Carlo, where a luxury property will set you back almost $4,500 a square foot, and Moscow, where that deluxe dacha will cost nearly $2,000 a square foot.
But even One Hyde Park can't hold a candle to the world's most over-the-top urban digs--the billion-dollar house in Mumbai, India, that the fourth-richest man on Forbes's list of the world's wealthiest calls home. All 27 stories of it.
