World's Most Expensive Homes

$125 million

Beverly Hills, Calif.

The latest addition to the $100 million-plus club, Suzanne Saperstein's gem is aptly called the Fleur de Lys. Modeled after Louis XIV's palace at Versailles, the 45,000-square-foot home took five years to build following Saperstein's accumulation of five acres in Holmby Hills during the 1990s. Should strolling the grounds bore you, there is a 50-seat screening room and a library filled with first-edition books. Auto collectors will salivate over the nine-car garage.

$125 million

Greenwich, Conn.

On 40 acres of rolling hills, with lawns and meadows broken by tree lines that provide privacy, this Jacobean manor has 21,897 square feet, 14 bedrooms and 13 bathrooms. Vaulted ceilings, travertine marble floors, bay windows, limestone walls and wood paneling are notable interior features of Dunnellen Hall, as is a 52-foot-long indoor swimming pool

$110 million

Windlesham, Surrey

Larger than either Buckingham or Hampton Court palace, this 103-room home has 58 acres of gardens and woodlands, making it the idyllic English country home for those flush with cash. Several ballrooms and grand entrance ways punctuate Updown Court, which has a panic room, an indoor squash court, bowling alley, 50-seat cinema, helipads, space for eight limousines and a heated marble driveway. Marble bathrooms are nice, but some would say indoor spas, Jacuzzis and pools with views of the grounds are better.

$100 million

Lake Tahoe, Nev.

Conveniently on the tax-free Nevada side of Lake Tahoe, this 210-acre property--Tranquility--is owned by Joel Horowitz, the co-founder of Tommy Hilfiger, who built the property from scratch. The main house has 20,000 square feet of living space, is modeled after a northern European mountain home and has a 3,500-bottle wine cellar. An indoor swimming pool and atrium, as well as a 19-seat movie theater, ensure constant entertainment, even if snowed in.

$100 million

Moscow, Russia

This sizable property consists of an 11,700-square-foot manor house, two 4,000-square-foot guest houses and a 91,000-square-foot recreation center that has a pool, Turkish and Russian baths, a gym, sauna and lounges. The estate--Eurasia--is 15 miles from the Moscow city center.

$95 million

Stamford, Conn.

With its stone construction, hedged gardens, grass tennis court, manicured gardens and distinctive chimneys, Hillandale has all the markings of an English country manor. The 20,000-square-foot residence has eight bedrooms and 10 bathrooms. It's so big that the property straddles the New York-Connecticut border. The grounds also include four guest and staff residences and two barns, all connected by five miles of private roads.

$88 million

Pagosa Springs, Colo.

We included the BootJack Ranch on our list because, while the price includes 3,100 acres of land, it's a luxury property more than a working ranch. The main house is 13,800 square feet and has four bedrooms and four bathrooms. Outlying guest cabins and lodges can host up to 50 people and bring the total interior space up to 77,000 square feet. In addition, there's a 12,000-square-foot spa and aquatic center.

$88 million

Côte d'Azur

On the French Riviera, this 11-bedroom, 14-bathroom mansion has 29,000 square feet of interior space that open to manicured lawns and a swimming pool. The spiraling outdoor staircases and plentiful balconies and terraces have views across the water and of the surrounding hillsides. Working fireplaces, a sauna, outdoor kitchen and pool house are other features at Villa Leopolda.

$85 million

Bel Air, Calif.

One of the last homes designed by famed California architect Wallace Neff, this estate rests on seven acres of land in the Holmby Hills area of Bel Air. Lawns, walking paths and gardens surround the 12-bedroom, 10-bathroom main house, and there's also a tennis court and pool. Inside, the home bends around a giant central atrium with curving hallways and overlooks.

$80 million

Southampton, N.Y.

The interior space of 13,500 square feet across four stories contains nine bedrooms, 11 bathrooms, four powder rooms and a movie theater. That's enough to catch anyone's eye, but what's really unique about this property is the waterfront. The home is situated between a pond and the ocean, and there is 1,000 feet of shore front and 1,000 feet of pond front.
