Your blood may not run blue, but with enough green you can still live near—and like—royalty. Updown Court is currently the most expensive residence in the world, costing about $50 million more than the priciest U.S. home. The brand-new property is totally over the top, with 103 rooms, five swimming pools and 24-carat-gold leafing on the study’s mosaic floor. There’s a squash court, bowling alley, tennis court, 50-seat screening room, heated marble driveway and helipad. All eight of your limousines will fit in the underground garage. Then there are the neighbors, who include the queen (at Windsor Castle) and Elton John. It is listed with Savills and Hamptons International.

Palatial homes and high property prices are common in New York’s favorite high-end resort area.

The 14 gardens include a crabapple allée; vegetable garden; lily walk; and rose, hydrangea and butterfly gardens. Of course, there are also the three ponds stocked with fish.

The triplex penthouse at the Pierre is the ne plus ultra of Manhattan apartment living—if one may prosaically call it that. The hotel’s top three floors, including the original Pierre ballroom with its 23-foot-high ceilings, offer 360-degree views of New York City from windows and terraces. The home features an opulent black marble staircase, 20-foot French windows, double reception rooms and a paneled library. Should the asking price seem too steep, the property is also available in two parts, at $11 million and $59 million. The latter, incidentally, would still make it onto our list. The listing brokers are Elizabeth Lee Sample and Brenda S. Powers at Brown Harris Stevens.

A large parcel of land is hard to come by in Malibu, a second home to movie stars and moguls.

The property includes a riding ring, gym, swimming pool, tennis court, guardhouse, and a private road to the beach. Jan Horn at Coldwell Banker has the listing.
