Tucked away on a private cul-de-sac off the highly desired Alameda Diablo, this residence offers a sophisticated take on farmhouse elegance within the prestigious Diablo Country Club community. A welcoming covered porch sets the tone for a home that perfectly balances great style with an inviting, lived-in feel. Inside, the grand entry gives way to wide white oak plank hardwood floors and a layout designed for effortless flow. The heart of the home is a crisp white chef’s kitchen, complete with a center island, window seat, a walk-in pantry, and a spacious eating area for casual morning coffee. For those who love to host, don't miss the beautiful formal living and dining rooms and the spacious great room featuring a built-in wet bar and wine refrigerator, all overlooking the inviting back porch and yard. With four fireplaces scattered throughout the home, there is a consistent sense of warmth and refinement. The primary suite is conveniently located on the first floor for ultimate privacy. Upstairs, accessible via both front and back staircases, you’ll find four additional bedrooms. Three of these include ensuite baths, while the fifth bedroom offers incredible versatility—perfectly suited as a spacious bonus room or a private au pair suite. The expansive grassy backyard provides a serene backdrop for outdoor living, with ample room to design a custom pool. This is a rare opportunity to enjoy a modern, thoughtfully designed home in a location defined by its heritage oaks and timeless character. Just steps or a golf cart ride away from the historic clubhouse, championship golf, and the unique, tight-knit spirit that defines life in Diablo. This isn’t just a home; it’s a chance to immerse yourself in a legacy in this wonderful community.
Mount Diablo Estate Park, located between Mount Diablo State Park and the Diablo Country Club, is a residential and park-adjacent Diablo neighborhood with oak-studded hillsides and winding private lanes. Character concentrates at the Diablo Road and Green Valley Road junction, where a quiet, equestrian-leaning atmosphere replaces storefront bustle. Architecture trends toward large, custom homes with long driveways, stone accents, and views framed by mature trees. Trailheads and open-space edges shape daily routines, with quick transitions from pavement to ridge-line paths. The Diablo Country Club clubhouse and grounds act as a central social landmark. The nearby Acalanes Ridge Open Space and Mount Diablo’s foothill corridors keep the setting distinctly outdoors-first.
