Located in one of Sacramento's most prestigious and established communities, 400 Crocker Road is a rare single-story estate offering the kind of scale, privacy, and timeless character that rarely becomes available in Sierra Oaks.Set on a beautifully curated 0.65-acre parcel, this custom ranch-style residence spans approximately 3,372 square feet of thoughtfully designed living space. A long private driveway welcomes you into a serene estate setting framed by mature landscaping originally conceived by renowned landscape designer Michael Glassman. Multiple fountains, intentionally designed seating areas, and a collection of mature citrus and fruit trees create an atmosphere that feels genuinely private and deeply personal from the moment you arrive.The single-story layout flows with architectural ease, featuring refinished neutral-toned hardwood flooring paired with an elegant selection of natural stone surfaces throughout, including marble, travertine, granite, and limestone. Plantation shutters and custom window treatments enhance every room, while the formal living and dining areas are anchored by a dramatic floor-to-ceiling fireplace surround that commands the space as a striking architectural focal point.The expansive family room offers its own dedicated fireplace, a built-in wet bar, and direct backyard access through a nearby full bathroom, creating a natural hub for poolside entertaining and relaxed everyday living. The gourmet gallery kitchen is a serious culinary environment appointed with Steel Grey granite countertops and a premier lineup of professional-grade appliances: a 36-inch Russell range with six 15,000 BTU burners, dual built-in Gaggenau ovens, a Miele stainless steel dishwasher, a 48-inch Sub-Zero built-in refrigerator and freezer with custom cabinet panels, and a U-Line beverage and wine refrigerator.The primary suite is in a category of its own. Designed with the vision of Dennis Haworth, this retreat is wrapped in timeless neutral-palette wallpaper and framed by large windows and glass doors on all sides that bring panoramic garden views directly into the room. The effect is quiet, restorative, and genuinely beautiful. A large walk-in closet features a fully custom built-in organizer system and an integrated built-in safe, offering both function and peace of mind. The spa-caliber primary bathroom is equally considered, with a jetted soaking tub, a beautifully skylit shower where natural light pours in through an overhead moon window, skylights throughout the space, dual sinks, and a refined vanity. Every detail reflects the kind of care that distinguishes a well-lived-in luxury home from one that simply looks the part.Two additional bedrooms feature abundant custom built-in cabinetry and exceptional storage throughout. All three full bathrooms showcase the same refined finishes and designer attention found consistently across the home.Outside, the resort-inspired backyard is designed for both everyday enjoyment and large-scale entertaining. A covered patio is ideal for al fresco dining, while raised planter beds with smart automatic irrigation, a built-in pool with discreetly positioned and shielded pool equipment, and multiple serene seating areas round out an outdoor living experience that is truly exceptional. The detached two-car garage includes additional workshop space suited for storage, hobbies, or creative projects. A newer air conditioning system delivers modern comfort and energy efficiency year-round.No HOA fees. No Mello-Roos. No restrictive community regulations. Ideally situated near the American River Parkway, downtown Sacramento, premier dining, top-tier shopping, and major commuter routes.Estates of this caliber in Sierra Oaks are genuinely rare. If you are looking for a single-story legacy home where design, privacy, and lifestyle converge at the highest level, 400 Crocker Road deserves your immediate attention.
