Perched high on the hill above the Carquinez Strait, this distinctive 4-bedroom, 3-bathroom tri-level home offers a wonderful blend of flexible living space, privacy, and modern technology. Situated on a beautifully maintained corner lot, this move-in-ready property is a rare find. A charming front porch welcomes you inside to an impressive entry boasting soaring ceilings, large sun-drenched windows, and gleaming hardwood floors. The formal dining room flows effortlessly into a spacious, upgraded kitchen featuring custom high ceilings—an ideal layout for entertaining. Upstairs houses three of the bedrooms and two full bathrooms. The main bedroom features its own ensuite bathroom and direct access to a private deck with peaceful, peekaboo water views. A second upstairs bedroom boasts mountain vistas, making it perfect for a dedicated work-from-home office, alongside a versatile third upstairs bedroom. The lower level offers incredible flexibility, featuring a privacy door that creates a self-contained space for the 4th bedroom, the 3rd full bathroom, a large family den, and a complete kitchenette. This setup is ideal for an independent in-law unit, guest wing, or rental potential. A sliding door leads out to a covered patio and a peaceful, lush garden that wraps around to a low-maintenance front yard. Equipped with a recently installed Tesla Powerwall, you will enjoy ultimate peace of mind with a reliable backup system that seamlessly provides up to 11.5 kW of continuous power during grid outages to run heavy loads like air conditioners and appliances. Lovingly maintained inside and out, this hilltop haven is completely ready for its next owner.
