The March 2007 issue of Architectural Digest contains a fascinating profile of Demi Moore and Ashton Kutcher's very private house at 9740 Oak Pass Road in Beverly Hills, Calif., which Moore bought in 2003 through her 4770 Trust for $3,150,000, according to public records.

The contemporary house, built in 1957, was the first of nine or 10 houses that Moore had looked at when she first started house-hunting in the Los Angeles area in 2003. "When we walked in," Moore told the magazine, "my kids whispered, 'This is the one.' It was ideal. It was right in the center of things, but it had such a serene quality. It was like being in a tree house."

Somewhat fittingly, then, public records show that Moore in 2006 changed the ownership of the house to the Tree House Trust--ostensibly a trust belonging both to her and Kutcher, whom she married in 2005. The seller of the house in 2003--a man named Herb Stewart, according to public records--had, 46 years earlier, built the secluded house on just under an acre on a canyon hillside in Beverly Hills, Architectural Digest reported. After taking possession of the house, Moore's biggest concern was fitting her three daughters' needs into the house's space--she told the magazine that "We had more kids than bedrooms"--and she and her then-boyfriend Kutcher set about expanding the house. They ultimately opted to build an addition containing two bedrooms, two baths and a children's den that would be cantilevered from the front so it would not interfere with the important views of oak and sycamore trees.

"My desire was to keep the integrity of what was already there," Moore told the magazine. "You feel the outside when you're inside. The house is part of nature, and nature rarely does it wrong. If we stick closely to it, we'll always be on the right track."

The addition was not insubstantial, according to public records. When Moore bought the house, it measured 4,515 square feet, according to the Los Angeles County Assessor's office. Today, the house measures 6,716 square feet.

The house has walls of windows, a two-story living room, and walls, floors and cabinets made of mahogany, teak and Brazilian rosewood, according to the magazine and listing information. Outside are a pool and deck and koi ponds, according to the magazine and listing information.

While the Architectural Digest article is not available online, an expired listing sheet from long ago is here, for a look at what the back of the house looks like.

So what happened to the house that Kutcher previously had occupied before moving in with Moore? Kutcher continues to own that house, which is at 9763 Suffolk Drive in Beverly Hills. Kutcher purchased the five-bedroom, 4,860-square-foot Suffolk Drive house, which was built in 1978, through his Vista Street Trust in May 2001 for $1,690,000. Kutcher leases that house out, according to news accounts. Kutcher called that trust the Vista Street Trust because his first L.A.-area house was a house at 1613 N. Vista Street in the Hollywood Hills, which he bought in 1999 for $560,000 and sold in 2001 for $620,000, according to public records.

The Suffolk Drive house also has the dubious distinction of having been the place where Kutcher has claimed that President Bush's twin daughters, Jenna and Barbara, had partied with him--and potentially had smoked marijuana--back in late 2001. The story must be taken with a grain of salt, given the prank-loving Kutcher's experiences on his TV show "Punk'd." But, the news media took very seriously Kutcher's recounting of his partying with the Bush twins, and the White House refused to comment. As the story goes, Kutcher met the Bush twins at a party in Los Angeles, and everyone ended up back at his house, with Kutcher asking Secret Service agents to stay outside. "The Bushes were underage-drinking at my house," Kutcher told the magazine. After stepping outside at one point to converse with the Secret Service agents, Kutcher said that "then I go upstairs to see another friend and I can smell the green wafting out under his door. I open the door, and there he is, smoking out the Bush twins on his hookah." Kutcher, who never retracted the story, told Rolling Stone that he believed that the Secret Service had tapped his phone ever since.

Moore also owns an estate in Hailey, Idaho. Probably the most well-known house she ever owned, however, was the 4,847-square-foot contemporary oceanfront house at 22470 Pacific Coast Highway in Malibu, Calif. that she owned with her ex-husband, Bruce Willis, until he sold it in 1999.
