World's Most Expensive Home

DEER VALLEY, Utah, Jan. 30, 2007 — -- On a mountaintop ridge in a Park City, Utah, community known as Deer Valley, a new home, complete with its own miniature ski lift, has just been put up for sale.

The owners are asking nearly $27 million -- a lot of money, but it seems positively affordable when compared with the price of a megamanse that has just been designed in the ultra exclusive Yellowstone Club in Big Sky, Mont.

Appropriately named "The Pinnacle," it's yours for $155 million.

Forbes Magazine calls it "The World's Most Expensive Home." A quick check reveals "The Pinnacle" just eclipsed the $139 million "Updown Court" in Windlesham, England, which used to hold the title and far outpaces Donald Trump's renovated estate in Palm Beach, Fla., that's going for $125 million.

So what justifies the "most expensive" asking price?

To begin with, the 10-bedroom, 53,000-square-foot, yes -- 53,000-square-foot -- home will sit on the most coveted piece of property in the resort. The 160 acres ought to provide ample elbow room for someone who has it all.

The home, which includes four guest cottages, will be built in the center of the ski resort and commands dramatic views in all directions. Take that, Chet Huntley, the NBC anchorman who created Big Sky Ski Resort just around the corner.

Jerry Locati, the Bozeman, Mont., architect who heads up Locati Architects, spent the last year designing the home and gave ABCNEWS.com an exclusive interview about what he calls "an incredibly unique, one-of-a-kind house."

"It's an adult, well, actually family-oriented home, a sort of Disneyland scale home for someone who is not afraid to spend money," he begins as he searches for superlatives. "It will have the usual home theater but will also include a bowling alley, an indoor-outdoor pool and an amazing wine cellar."

The house, which has a rustic exterior crafted out of stone, hand-hewn beams and ample floor-to-ceiling glass, includes a huge underground garage.

"You'll be able to park 30 or 40 cars," Locati says. "Perfect for someone with a car collection and of course the ideal service entrance for caterers."
