Foreboding 10-Acre California Estate Inspired by a Japanese Castle Is Listed for $8.2 Million—Complete With a Koi Pond

Wellness-focused dwellings have surged in popularity in recent years—but one rare gem in San Luis Obispo, CA, is offering a sanctuary of tranquility in which a buyer can enjoy not just a state of Zen, but also living spaces fit for royalty.

Inspired by a castle in Ishigaki, an island city located south of Japan, the extraordinary estate is the perfect blend of “Eastern tranquility and Western luxury,” having been designed as a “sanctuary” from the outside world.

Perched atop a hill overlooking the Edna Valley, the dwelling offers “commanding 360-degree views” of the land below, including a championship golf club, nearby vineyards, and even a glimpse of the Pacific Ocean.

The 10-acre property—which is on the market for $8.2 million—is anchored by a home built in 2008. However, its design was inspired by centuries-old architecture, which the owners fell in love with while spending time in Asia, according to listing agents Lindsey HarnColleen Clarke, and Rob Rose with Christie’s International Real Estate Sereno.

“The owners spent many years living in Asia, so there’s this Asian element,” Clarke tells Realtor.com®.

The castle-style design ensures wide open spaces filled with light—but Clarke hastens to note that the home still provides plenty of warmth

“It’s a very open, very spacious design with really high ceilings but doesn’t have the coldness that a modern architectural home might have, because of the use of stone and wood,” she adds.

Radiant floor heating is another cozy perk, and there’s a four-car garage.

The 6,971-square-foot, single-level home with six bedrooms and six baths also features custom woodwork, including walnut flooring, doors, cabinets, and trim.

In the kitchen are Sub-Zero, BlueStar, Miele, and Bosch appliances. The primary suite features a luxurious bath with a soaking tub, marble shower with 11 shower heads, and a six-person Finlandia sauna.

“It really feels approachable,” Harn explains. “You don’t feel like you’re walking into a castle or a palace. It feels cozy. You can do all of your main living on one level. It’s one of the highest points for a built home in the Edna Valley.”

 

 

 

 

 

There are other tie-ins with nature, too. For example, when a giant walnut tree fell nearby, the homeowners had it milled and used it in the art deco home theater’s paneling. The space also features a dome and hand-painted galaxy mural.

Outdoor amenities include an infinity pool and spa, which blend into the hillside; a koi pond; and three travertine patios.

The home is just a 10-minute drive from downtown San Luis Obispo and five minutes to the SLO County Airport.

“It’s hard to find something that has space and privacy that is so close to town,” Clarke says. “You’re so high you can see hawks flying beneath you when you look out the window, and yet it’s only a 2-minute drive up [the hill].”

Because there’s been only one owner, the condition is immaculate. “They’ve been super, super meticulous and maintained it to a level where it feels like it could have been built yesterday,” says Harn.
