Explore bold, ‘refreshing,’ geometric home in Northern California wine country (2025)

“The House of Angles” in Northern California wine country is described as bold, refreshing and distinctive.

The three-bedroom, two-bathroom masterpiece in Santa Rosa spans 2,356 square feet and stands out for its geometric design, abundance of natural light, panoramic views and energy efficiency. Listed for $2.275 million, the Sonoma County gem sits on more than three acres with a half-acre of Chardonnay grapes.

The centerpiece elements of the residence are the light-filled double living areas with soaring ceilings framed by expansive walls of glass.

It’s safe to say nobody will ever call the home in the Loch Haven community boring or average.

“With statistics showing that tract homes make up 60 to 90% of cities, it’s always refreshing to have such thoughtful engineering and design put into something you will call home ... so it’s a rare offering in that regard,” Rachel Swann of Coldwell Banker Realty, said in an email. “Given the economic cost of building and carrying the cost to create a residence of this level of craftsmanship, it’s actually more attainable and affordable than ever to have a unique dream home in these types of rare offerings than it is to build it new.”

The house, 10045 Loch Haven Drive, was designed by architect Ken O’Connor and built in 1983.

The sellers have owned the home since 2014 and emphasize the property’s serenity and easy access to Santa Rosa and St. Helena’s shops and restaurants and to wineries in Sonoma and Napa counties.

Owner Jim Dugan pointed out a few of its unique design qualities.

“The engineer who had the residence built was very involved, especially in terms of placement for light,” Dugan said in an email. “Every window has an expansive view. Ken O’Connor‘s trademark was the circular window that he featured in all his properties, and that is always commented on by all who have come to visit.”

The home spotlights numerous private alcoves, including a hot tub level. Unobstructed views take in the property’s natural setting among trees, vines, pastures and hills.

The property uses solar energy from photovoltaic panels.

The chef’s kitchen overlooks the spacious living and formal dining areas.

The home’s sprawling decks overlook the vineyard of Chardonnay grapes and allows for indoor-outdoor entertaining.

The upper-level primary suite showcases a private, interior loft that is, in essence, an indoor balcony that mirrors the outdoor deck with both offering stunning views of the home’s natural setting.

The residence is near the equestrian and hiking trails of Safari West, a 400-acre wildlife preserve often referred to as the “Sonoma Serengeti.” It’s home to more than 1,000 animals and nearly 100 species.

“This amenity allows residents to explore its scenic trails and immerse themselves in the preserve’s natural beauty at their leisure,” a Coldwell Banker representative said in an email.
