"Rock House" still on the market

Maybe the biggest Craftsman-style home in Southern California, if not the U.S.

People on the other side of the canyon may not notice the house because of its paint job.

Current Owner: Coseo Family Trust

Bedrooms: 6

Baths: 11

Price: $11,250,000

The “Rock House” sits atop a hillside in northern Poway, constructed in 2008 on a parcel over eight acres in size. The 14,614-square-foot estate was named for the extensive use of decorative rocks on the home’s exterior walls, patios, and walkways.

“All the rock on the outside was actually mined from the site itself,” says Coronado Island Realty listing agent Cote Perkins. “The sellers mined twice with dynamite, which not only yielded the rock but is also how they got the subterranean wine cellar and theater.”

Rock House was designed with the help of Solana Beach–based architect John Jensen and interior designer Joe McCarter of Encinitas.

“McCarter specializes in lighting, so all of the lighting in there is custom, and there’s a lot of mica stone featured — a thin, shiny type of rock. It was all assembled on site and creates lighting features that are really unique to the property,” says Perkins.

The home was built in the American Craftsman style popular in the late 19th and early 20th Centuries. Interior features include a wood-paneled elevator, 2000-bottle wine cellar, a theater with eight recliners and a bar to seat another four, a billiards and game room, and a master suite with a 756-square-foot bedroom area (not including the walk-in closet or master bath) that has temperature-controlled flooring. Exposed wood beam and paneled-wood ceilings are on display throughout the interior.

“As far as I know it’s the biggest Craftsman-style home in Southern California, if not the U.S. — it took a full four years to build,” Perkins speculates.

“The house actually features over 15,000 board feet of mahogany wood, which is used in the wainscoting on the interior walls, in the elevator, and other locations. It actually created a mahogany shortage at the time the owner was building.”

Outdoors, the home features a “summer kitchen” with wood-burning pizza oven, lighted tennis court, and a fire pit in the outdoor living space alongside a disappearing-edge pool. Other design features include English slate tile roofing, a 6-car garage (which Perkins suggests could be expanded to fit up to 12 vehicles), and an indoor/outdoor viewing deck on the home’s third level above grade.

“What’s really interesting about the home is how it’s painted green on the outside — when you’re looking out at the view, to the people on the other side of the canyons looking at the home they can’t really make out that there’s a house there, which adds to the overall privacy,” Perkins adds.

Public records list the Coseo family trust as the Rock House’s current owner. Chris Coseo is the president of Coseo Properties, Inc., a real estate investment and development company with residential and commercial holdings around San Diego and across the country.

The home was first listed for sale in April 2013, but a buyer did not swoop in to pick it up for the asking price of $12,500,000. The listing was renewed this past April, with a price of $11,250,000, which remains unchanged to date.
