    What's special

    Expansive workshopOriginal hardwood floorsPrivacy and peaceful setting
    Tucked along a quiet Castro Valley street, this inviting home offers the perfect balance of timeless character, everyday comfort, and exciting potential. From the moment you arrive, there's a sense that this is a home that's been thoughtfully cared for and is ready for its next chapter. Inside, hardwood floors add warmth throughout much of the home, while the functional four-bedroom, two-bath layout provides flexibility for growing families, remote work, or multigenerational living. Every space feels comfortable, welcoming, and filled with natural light. The heart of the home is the expanded dining room, where walls of windows frame views of the backyard and create an airy gathering space for everything from casual breakfasts to holiday celebrations. It's a room designed for connection and one that naturally draws everyone together. Outside, the property continues to impress with multiple outdoor spaces to relax, entertain, garden, or simply enjoy the peaceful surroundings. Above the backyard, the detached structure has been transformed into a versatile bonus room. Beneath it, a spacious workshop offers exceptional flexibility for hobbies, storage, creative studio, or the potential to explore an ADU conversion (buyer to verify). Whether you're looking for a home to enjoy immediately or one you can thoughtfully personalize over time, this property offers the rare combination of move-in-ready comfort, versatile spaces, and the opportunity to build lasting value in a desirable Castro Valley location.
